             Summary: Compiler is crashing while setting module version
                 Key: MCOMPILER-446
                 URL: https://issues.apache.org/jira/browse/MCOMPILER-446
             Project: Maven Compiler Plugin
          Issue Type: Bug
    Affects Versions: 3.8.1
            Reporter: Bruno Medeiros


I have upgraded maven compiler plugin to 3.8.1 and I started getting this error:
{code:java}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project common: Fatal error compiling: error: bad value for --module-version option: 'local-SNAPSHOT' -> [Help 1]{code}
Because we set versions in pom to local-SNAPHOT (and use maven-version-plugin when we actually realease to set a proper version), all our builds are failing locally.

It seems javac does not like versions that do not have just alpha characters, like ours local-SNAPHOT.

I thought about a few ways to fix that:
 * Allow the use of --module-version to be optional through config
 * Allow the version itself to be configurable
 * Validate if the version is a valid version for --module-version and not set it in case it is not

Let me know what you guys think, I can try to provide a PR with the given solution.
