"invalid target release: 14"

[ZeeD]

I have enabled the codeql analysis on https://github.com/ZeeD/springbootplusdbunit
the project itself it's just a simple personal demo of integration. The pom is almost the same from https://start.spring.io/
unfortunately the autobuild step ended with error, and the cause is the title of the message.

I suspect the problem is just that it's not installed / used the latest jdk version, because I see Java version: 1.8.0_252, vendor: AdoptOpenJDK, runtime: /usr/lib/jvm/adoptopenjdk-8-hotspot-amd64/jre in the autobuild logs while java 14 is in GA.

It's possible to update the java version to the latest stable one?

It looks like the default JDK version in an Actions VM is 8. For reference: https://github.com/actions/virtual-environments/blob/master/images/linux/scripts/installers/java-tools.sh#L26

I'd recommend using the actions/setup-java Action to select the Java version to use.

the actions/setup-java Action did the trick, thanks.
maybe it would be useful to put

    - name: Setup Java JDK
      uses: actions/setup-java@v1.3.0
      with:
        java-version: 14

with java-version commented out or autoinferred from the .pom properties in the automatically generated .yaml file

Glad that got it working for you. I'm going to close this issue as the original point has been satisfied. I'll create an issue internally for the feature improvement of autogenerating a setup-java step if the repo has a pom file.
