Build outputs

It appears that when restoring the Gradle User Home directory, certain empty
directories are being identified by Node as broken symlinks. This results in
`Error: ENOENT: No such file or directory` when attempting to resolve a Glob pattern.

By using the default behaviour of Globber (followSymbolicLinks && ignoreBrokenLinks),
these bad files no longer cause errors when saving the Gradle User Home to cache.

Fixes #408

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

 # Execute Gradle builds in GitHub Actions workflows
 
-This GitHub Action can be used to execute a Gradle build on any platform supported by GitHub Actions.
+This GitHub Action can be used to configure Gradle and optionally execute a Gradle build on any platform supported by GitHub Actions.
 
-**Note:** The following documentation is for `gradle/gradle-build-action@v2`, currently in Beta release.
-You can view the documentation for the latest stable release (v1.5.1) [on the GitHub Marketplace](https://github.com/marketplace/actions/gradle-build-action?version=v1.5.1). 
+## Use the action to setup Gradle
 
-## Usage
+If you have an existing workflow invoking Gradle, you can add an initial "Setup Gradle" Step to benefit from caching, 
+build-scan capture and other features of the gradle-build-action.
 
-The following workflow will run `./gradlew build` on ubuntu, macos and windows. 
-The only prerequisite is to have Java installed: you define the version of Java you need to run the build using the `actions/setup-java` action.
+All subsequent Gradle invocations will benefit from this initial setup, via `init` scripts added to the Gradle User Home.

+```
+
+## Why use the `gradle-build-action`?
+
+It is possible to directly invoke Gradle in your workflow, and the `actions/setup-java@v3` action provides a simple way to cache Gradle dependencies. 
+
+However, the `gradle-build-action` offers a number of advantages over this approach:
+
+- Easily [run the build with different versions of Gradle](#download-install-and-use-a-specific-gradle-version) using the `gradle-version` parameter. Gradle distributions are automatically downloaded and cached. 
+- More sophisticated and more efficient caching of Gradle User Home between invocations, compared to `setup-java` and most custom configurations using `actions/cache`. [More details below](#caching).
+- Detailed reporting of cache usage and cache configuration options allow you to [optimize the use of the GitHub actions cache](#optimizing-cache-effectiveness).
+- [Automatic capture of build scan links](#build-scans) from the build, making these easier to locate for workflow run.
+
+The `gradle-build-action` is designed to provide these benefits with minimal configuration. 
+These features work both when Gradle is executed via the `gradle-build-action` and for any Gradle execution in subsequent steps.
+
+When using `gradle-build-action` we recommend that you _not_ use `actions/cache` or `actions/setup-java@v3` to explicitly cache the Gradle User Home. Doing so may interfere with the caching provided by this action.
+
+## Use a specific Gradle version
+
+The `gradle-build-action` can download and install a specified Gradle version, adding this installed version to the PATH.
+Downloaded Gradle versions are stored in the GitHub Actions cache, to avoid requiring downloading again later.
+
+```yaml
+ - uses: gradle/gradle-build-action@v2
+   with:
+     gradle-version: 6.5
+```
+
+The `gradle-version` parameter can be set to any valid Gradle version.
+
+Moreover, you can use the following aliases:
+
+| Alias | Selects |
+| --- |---|
+| `wrapper`           | The Gradle wrapper's version (default, useful for matrix builds) |
+| `current`           | The current [stable release](https://gradle.org/install/) |
+| `release-candidate` | The current [release candidate](https://gradle.org/release-candidate/) if any, otherwise fallback to `current` |
+| `nightly`           | The latest [nightly](https://gradle.org/nightly/), fails if none. |
+| `release-nightly`   | The latest [release nightly](https://gradle.org/release-nightly/), fails if none.      |
+
+This can be handy to automatically verify your build works with the latest release candidate of Gradle:
+
+```yaml
+name: Test latest Gradle RC

+  schedule:
+    - cron: 0 0 * * * # daily

 ```
 
+## Gradle Execution
+
+If the action is configured with an `arguments` input, then Gradle will execute a Gradle build with the arguments provided.
+
+If no `arguments` are provided, the action will not execute Gradle, but will still cache Gradle state and configure build-scan capture for all subsequent Gradle executions.

+Distributions downloaded to satisfy a `gradle-version` parameter are stored outside of Gradle User Home and cached separately. The cache key is unique to the downloaded distribution and will not change over time.

 ### Using the caches read-only
 
-Cache storage space is limited for GitHub actions, and writing new cache entries can trigger the deletion of exising entries.
-In some circumstances, it makes sense for a Gradle invocation to read any existing cache entries but not to write changes back.
-For example, you may want to write cache entries for builds on your `main` branch, but not for any PR build invocations.
+By default, the `gradle-build-action` will only write to the cache from Jobs on the default (`main`/`master`) branch.
+Jobs on other branches will read entries from the cache but will not write updated entries. 
+See [Optimizing cache effectiveness](#optimizing-cache-effectiveness) for a more detailed explanation.
 
-You can enable read-only caching for any of the caches as follows:
+In some circumstances it makes sense to change this default, and to configure a workflow Job to read existing cache entries but not to write changes back.
+
+You can configure read-only caching for the `gradle-build-action` as follows:
 
 ```yaml
-cache-read-only: true
+# Only write to the cache for builds on the 'main' and 'release' branches. (Default is 'main' only.)
+# Builds on other branches will only read existing entries from the cache.
+cache-read-only: ${{ github.ref != 'refs/heads/main' && github.ref != 'refs/heads/release' }}
 ```
 
-### Cache debugging
+### Stopping the Gradle daemon
 
-It is possible to enable additional debug logging for cache operations. You do via the `CACHE_DEBUG_ENABLED` environment variable:
+By default, the action will stop all running Gradle daemons in the post-action step, prior to saving the Gradle User Home state. 
+This allows for any Gradle User Home cleanup to occur, and avoid file-locking issues on Windows.
+
+If caching is unavailable or the cache is in read-only mode, the daemon will not be stopped and will continue running after the job is completed.
+
+### Gradle User Home cache tuning
+
+As well as any wrapper distributions, the action will attempt to save and restore the `caches` and `notifications` directories from Gradle User Home.
+
+The contents to be cached can be fine tuned by including and excluding certain paths with Gradle User Home.
+
+```yaml
+# Cache downloaded JDKs in addition to the default directories.
+gradle-home-cache-includes: |
+    caches
+    notifications
+    jdks
+# Exclude the local build-cache from the directories cached.
+gradle-home-cache-excludes: |
+    caches/build-cache-1
+```
+
+You can specify any number of fixed paths or patterns to include or exclude. 
+File pattern support is documented at https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#patterns-to-match-file-paths.
+
+### Cache debugging and analysis
+
+Gradle User Home state will be restored from the cache during the first `gradle-build-action` step for any workflow job. 
+This state will be saved back to the cache at the end of the job, after all Gradle executions have completed.
+A report of all cache entries restored and saved is printed to the Job Summary when saving the cache entries. 
+This report can provide valuable insignt into how much cache space is being used.
+
+It is possible to enable additional debug logging for cache operations. You do via the `GRADLE_BUILD_ACTION_CACHE_DEBUG_ENABLED` environment variable:
 
 ```yaml
 env:
-  CACHE_DEBUG_ENABLED: true
+  GRADLE_BUILD_ACTION_CACHE_DEBUG_ENABLED: true
 ```
 
 Note that this setting will also prevent certain cache operations from running in parallel, further assisting with debugging.
 
+### Optimizing cache effectiveness
+
+Cache storage space for GitHub actions is limited, and writing new cache entries can trigger the deletion of existing entries.
+Eviction of shared cache entries can reduce cache effectiveness, slowing down your `gradle-build-action` steps.
+
+There are a number of actions you can take if your cache use is less effective due to entry eviction.
+
+#### Select branches that should write to the cache
+
+GitHub cache entries are not shared between builds on different branches. 
+This means that each PR branch will have it's own Gradle User Home cache, and will not benefit from cache entries written by other PR branches.
+An exception to this is that cache entries written in parent and upstream branches are visible to child branches, and cache entries for the default (`master`/`main`) branch can be read by actions invoked for any other branch.
+
+By default, the `gradle-build-action` will only _write_ to the cache for builds run on the default (`master`/`main`) branch. 
+Jobs run on other branches will only read from the cache. In most cases, this is the desired behaviour, 
+because Jobs run against other branches will benefit from the cache Gradle User Home from `main`, 
+without writing private cache entries that could lead to evicting shared entries.
+
+If you have other long-lived development branches that would benefit from writing to the cache, 
+you can configure these by overriding the `cache-read-only` action parameter. 
+See [Using the caches read-only](#using-the-caches-read-only) for more details.
+
+Similarly, you could use `cache-read-only` for certain jobs in the workflow, and instead have these jobs reuse the cache content from upstream jobs.
+
+#### Exclude content from Gradle User Home cache
+
+Each build is different, and some builds produce more Gradle User Home content than others.
+[Cache debugging ](#cache-debugging-and-analysis) can provide insight into which cache entries are the largest,
+and you can selectively [exclude content using `gradle-home-cache-exclude`](#gradle-user-home-cache-tuning).
+
+## Saving build outputs
+
+By default, a GitHub Actions workflow using `gradle-build-action` will record the log output and any Build Scan links for your build,
+but any output files generated by the build will not be saved.
+
+To save selected files from your build execution, you can use the core [Upload-Artifact](https://github.com/actions/upload-artifact) action.
+For example:
+
+```yaml
+jobs:   
+  gradle:
+    runs-on: ubuntu-latest
+    steps:
+    - name: Checkout project sources
+      uses: actions/checkout@v3
+    - name: Setup Gradle
+      uses: gradle/gradle-build-action@v2
+    - name: Run build with Gradle wrapper
+      run: ./gradlew build --scan
+    - name: Upload build reports
+      uses: actions/upload-artifact@v3
+      with:
+        name: build-reports
+        path: build/reports/
+```
+
 ## Build scans
 
 If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-build-action` action will:
 - Add a notice with the link to the GitHub Actions user interface
-- Emit the link to the published build scan as an output named `build-scan-url`.
+- For each step that executes Gradle, adds the link to the published build scan as a Step output named `build-scan-url`.
 
 You can then use that link in subsequent actions of your workflow. For example:

+## Support for GitHub Enterprise Server (GHES)
+
+You can use the `gradle-build-action` on GitHub Enterprise Server, and benefit from the improved integration with Gradle. Depending on the version of GHES you are running, certain features may be limited:
+- Build scan links are captured and displayed in the GitHub Actions UI
+- Easily run your build with different versions of Gradle
+- Save/restore of Gradle User Home (requires GHES v3.5+ : GitHub Actions cache was introduced in GHES 3.5)
+- Support for GitHub Actions Job Summary is not yet available in any version of GHES. Instead of producing a Job Summary, the build-results summary and caching report will be written to the workflow log, as part of the post-action step.
