## Apache Maven with a settings path
When using an Actions self-hosted runner with multiple shared runners the default `$HOME` directory can be shared by a number runners at the same time which could overwrite existing settings file. Setting the `settings-path` variable allows you to choose a unique location for your settings file.
```yaml
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Set up JDK 11 for Shared Runner
uses: actions/setup-java@v2
with:
distribution: '<distribution>'

## Hosted Tool Cache
GitHub Hosted Runners have a tool cache that comes with some Java versions pre-installed. This tool cache helps speed up runs and tool setup by not requiring any new downloads. There is an environment variable called `RUNNER_TOOL_CACHE` on each runner that describes the location of this tools cache and this is where you can find the pre-installed versions of Java. `setup-java` works by taking a specific version of Java in this tool cache and adding it to PATH if the version, architecture and distribution match.

Currently, LTS versions of Adopt OpenJDK (`adopt`) are cached on the GitHub Hosted Runners.
The tools cache gets updated on a weekly basis. For information regarding locally cached versions of Java on GitHub hosted runners, check out [GitHub Actions Virtual Environments](https://github.com/actions/virtual-environments).
