### Using Microsoft distribution on GHES

`setup-java` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading the Microsoft Build of OpenJDK distribution, `setup-java` makes a request to `actions/setup-java` to get available versions on github.com (outside of the appliance). These calls to `actions/setup-java` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If more requests are made within the time frame, then you will start to see rate-limit errors during downloading that looks like: `##[error]API rate limit exceeded for...`.

To get a higher rate limit, you can [generate a personal access token on github.com](https://github.com/settings/tokens/new) and pass it as the `token` input for the action:

```yaml
uses: actions/setup-java@v3
with:
token: ${{ secrets.GH_DOTCOM_TOKEN }}
distribution: 'microsoft'
java-version: '11'
```

If the runner is not able to access github.com, any Java versions requested during a workflow run must come from the runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)" for more information.
