Issue targeting JDK with JAVA_HOME

[justinwb]

Getting the following when specifying JDK11 per the instructions in the README. When nothing is specified for JAVA_HOME it defaults to the latest JDK as expected, which generally works but I have one configuration with a dependency configuration that doesn't play well with latest.

Run qcastel/github-actions-maven-cmd@master
  with:
    maven-args: clean install -Ddockerfile.skip -DdockerCompose.skip -Djib.skip
