Extract and set version in module fixing process

[sormuras]

The modulefixer should extract the (raw) version string from the plain JAR it processes and set the extracted version into the generated module.

Sources of version strings:

• Extract META-INF manifest attribute Implementation-Version value, if available.
• JAR file name convention used by Maven: <groupId>:<artifactId>[:<extension>[:<classifier>]]:<version>

I believe the former is doable but the later requires to have the Maven information inside the jar There is no from the repository at the time the module-fixer is executed because the jar is downloaded by the resolver before. But maybe, you are thinking about a specific file which is inserted into the jar if it is built with Maven ?

Mh, no. There's none I know of.

For me (JUnit) it would suffice if a manifest attribute like Implementation-Version is extracted and used by the fixer.
