[scala-tools] Enforcing Scala version with Maven

[bearfeeder]

Folks,

Is there any way we can use Maven to enforce Scala versions such that libraries compiled with a certain version of Scala can only be used with the same version of Scala?

Thanks,

David

Yes, there is a configuration parameter to do this.  Unfortunately, a lot of libraries have scala-library listed as a "provided" dependency, which does not get enforced.

I believe Heiko already sent the configuration parameter you can use.

Josh,

The parameter will *not* make the build fail but only log with a leading "error" instead of a leading "warning". The Mojo should additionally throw an Exception. I did this locally and it worked. If you give me access to the repo I will patch it.

I fixed it in ScalaMojoSupport.checkArtifactForScalaVersion().

Even before the fix I could not build successfully (see below). Hence I had to remove the maven-invoker-plugin from the POM. Then I could successfully test my fix with ScalaModules.

I pushed the fix as a new branch wip-scala-versions. If you merge it, please take care of my temporary change in the POM.

The build error:

[ERROR] The following builds failed:

[ERROR] *  testLotsofJavaFiles/pom.xml

[ERROR] *  testLotsofJavaFilesNoFork/pom.xml

[ERROR] *  vscaladocOnMultiModules/pom.xml

[INFO] ---------------------------------------

[INFO] ------------------------------------------------------------------------

[ERROR] BUILD FAILURE

[INFO] ------------------------------------------------------------------------

[INFO] : org.apache.maven.plugin.invoker.InvokerMojo@cbb3fa

3 builds failed.

Cheers
