Cross compiling Scala jars with

[Mark Butler]

Hi,

I want to cross compile a Scala jar using the Scala Maven plugin. I am following the instructions here:

https://groups.google.com/forum/#!searchin/maven-and-scala/cross/maven-and-scala/qpqBVuDg4Gk/hIWKKbtM5dIJ

However it does not make the artifact id correctly - if I take this approach:

   <artifactId>myjar_${scalaVersion}</artifactId>

Then if scalaVersion is defined in pom.xml - for example if I give it an initial value then override it with the profile - it takes the initial value, not the version supplied at the command line via:

     mvn -DscalaVersion=2.11

My initial value was 2.10 so I keep getting error messages like this when I try to use the jar:

   > inconsistent module metadata found. 

   Descriptor: myorg:myjar_2.10:0.1-SNAPSHOT 

   Errors: bad module name: expected='myjar_2.11' found='myjar_2.10'

If I don't give it an initial value then this happens:

   > inconsistent module metadata found. 

   Descriptor: myorg:myjar_${scalaVersion}:0.1-SNAPSHOT 

   Errors: bad module name: expected='myjar_2.11' found='myjar_${scalaVersion}'

Maybe something changed in Maven since David wrote his FAQ?

Does anybody know any way around this? I tried searching Github but I couldn't find any example of using Maven to cross compile for Scala.

Thanks!

Mark

Hi,

Can you share a sample project on github/bitbucket, then we can iterate on an uptodate solution ?

Which version of maven do you use ?
