Truncate Gradle args when constructing cache key (#71)

Cache keys have a hard limit of 512 characters, so we need to ensure that we don't generate a key longer than this.

- Remove excess whitespace
- Truncate to 400 characters

Fixes #70

-# Build scans
+## Caching
 
-If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-command-action` action will emit the link to the published build scan as an output named `build-scan-url`.
+This action provides 3 levels of caching to help speed up your GitHub Actions:
+
+- `distributions` caches any downloaded Gradle zips, including any downloaded [wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html) versions, saving time downloading Gradle distributions ;
+- `dependencies` caches the [dependencies](https://docs.gradle.org/current/userguide/dependency_resolution.html#sub:cache_copy), saving time downloading dependencies ;
+- `configuration` caches the [build configuration](https://docs.gradle.org/nightly/userguide/configuration_cache.html), saving time configuring the build.
+
+Only the first one, caching downloaded distributions, is enabled by default.
+Future versions of this action will enable all caching by default.
+
+You can control which level is enabled as follows:
+
+```yaml
+distributions-cache-enabled: true
+dependencies-cache-enabled: true
+configuration-cache-enabled: true
+```
+
+NOTE: The `wrapper-cache-enabled` flag has been deprecated, replaced by `distributions-cache-enabled` which enables caching for all downloaded distributions, including Gradle wrapper downloads.
+
+The distributions cache is simple and can't be configured further.
+
+The dependencies and configuration cache will compute a cache key in a best effort manner.
+Keep reading to learn how to better control how they work.
+
+Note that enabling configuration cache without the dependencies cache is not permitted, since a hit in the configuration cache assumes that dependencies are already present in the local dependencies cache.
+
+### Configuring the dependencies and configuration caches
+
+Both the dependencies and configuration caches use the same default configuration:
+
+They use the following inputs to calculate the cache key:
+
+```text
+**/*.gradle
+**/*.gradle.kts
+**/gradle.properties
+gradle/**
+```
+
+This is a good enough approximation.
+They restore cached state even if there isn't an exact match.
+
+If the defaults don't suit your needs you can override them with the following inputs:
+
+```yaml
+dependencies-cache-key: |
+  **/gradle.properties
+  gradle/dependency-locks/**
+dependencies-cache-exact: true
+configuration-cache-key: |
+  **/gradle.properties
+  gradle/dependency-locks/**
+configuration-cache-exact: true
+```
+
+Coming up with a good cache key isn't trivial and depends on your build.
+The above example isn't realistic.
+Stick to the defaults unless you know what you are doing.
+
+If you happen to use Gradle [dependency locking](https://docs.gradle.org/current/userguide/dependency_locking.html) you can make the dependencies cache more precise with the following configuration:
+
+```yaml
+dependencies-cache-enabled: true
+dependencies-cache-key: gradle/dependency-locks/**
+dependencies-cache-exact: true
+```
+
+### 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 use any existing cache entries but not to write and changes back.
+For example, you may want to write cache entries for builds on your `main` branch, but not for any PR build invocations.
+
+Use the following configuration to avoid writing cache entries for the action invocation:
+
+```yaml
+cache-read-only: true
+```
+
+## Build scans
+
+If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-build-action` action will emit the link to the published build scan as an output named `build-scan-url`.
 
 You can then use that link in subsequent actions of your workflow.
