GitHub Action
Setup AdoptOpenJDK
This action sets up a Java development environment with the OpenJDK distribution from AdoptOpenJDK for use in actions by:
- Downloading and caching a version of the OpenJDK by version and adding to
PATH
. Downloads from AdoptOpenJDK. - Registering problem matchers for error output.
The action is based on actions/setup-java and is using the AdoptOpenJDK API for fetching the JDK binaries.
See action.yml

The two settings.xml
files created from the above example look like the following.
settings.xml
file created for the first deploy to GitHub Packages
<servers>
<server>
<id>github</id>
<username>${env.GITHUB_ACTOR}</username>
<password>${env.GITHUB_TOKEN}</password>
</server>
</servers>
settings.xml
file created for the second deploy to Apache Maven Central
<servers>
<server>
<id>maven</id>
<username>${env.MAVEN_USERNAME}</username>
<password>${env.MAVEN_CENTRAL_TOKEN}</password>
</server>
</servers>
NOTE: The settings.xml
file is created in the Actions $HOME directory. If you have an existing settings.xml
file at that location, it will be overwritten. See below for using the settings-path
to change your settings.xml
file location.
If you don't want to overwrite the settings.xml
file, you can set overwrite-settings: false
.
See the help docs on Publishing a Package for more information on the pom.xml
file.

NOTE: The USERNAME

need to correspond to the credentials environment variables used in the publishing section of your build.gradle
.
See the help docs on Publishing a Package with Gradle for more information on the build.gradle
configuration file.
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.
