@joschi -- what about, as quick & dirty work-around that will stay forever, repackaging the .tar.gz downloaded from java.net to conform the expectations of actions/setup-java?

[Jochen Schalanda]

That would certainly be possible, but I'm not sure that you would want to maintain this.

There's a new type of action: https://docs.github.com/en/free-pro-team@latest/actions/creating-actions/creating-a-composite-run-steps-action

Composite run steps actions
A composite run steps action allows you to combine multiple workflow run steps within one action. For example, you can use this feature to bundle together multiple run commands into an action, and then have a workflow that executes the bundled commands a single step using that action.

As this action type is supported on all platforms, I consider porting this action from JavaScript to "composite-run-steps".

        if [ "$RUNNER_OS" == "macOS" ]; then
          JDK_EXTRACTED=${HOME}/downloaded-jdk-${{ inputs.feature }}
          mkdir ${JDK_EXTRACTED}
          tar --extract --file ${JDK_FILE} -C ${JDK_EXTRACTED} --strip-components 4
          rm ${JDK_FILE}
          tar --create --file ${JDK_FILE} -C ${HOME} downloaded-jdk-${{ inputs.feature }}          
        fi

Almost!

On Mac OS and Java 9..13 the setup-java actions errors with:

Error: no such file or directory: /Users/runner/work/_temp/temp_241785471/downloaded-jdk-13/libjli.dylib
