problem running scalac from maven-scala-plugin for project with many java classes

[Peter Lopen]

hello,

I have a following problem, while using scala-maven-plugin for project with many java source files:

lopen@LOPEN /d/devel/eai/migration
$ mvn -e -Dmaven.scala.displayCmd=true -Dmaven.test.skip=true clean install

When I've removed list of *.java files, command for compilation runs correctly. Is there any other possibility to define java source files for scala compiler using scala-maven-plugin?

Thanks.

Peter,

I have a fix that should work for you.  You need to do the following:

1) Pull down the maven-scala-plugin source (git clone git://github.com/davidB/maven-scala-plugin.git )
2) Run [mvn install] on the maven-scala-plugin.
3) Add a <fork>false</fork>   element in the maven-scala-plugin configuration section.
4) You may need to increase the memory given to the maven process.  I believe the command is something like [set MAVEN_OPTS="-Xmx512M"]
5) You may also need to specify 2.10-SNAPSHOT as the version of your maven-scala-plugin, but you should not have to.


I was able to duplicate the error you saw by attempting to build 514 source files.   Using the above fixes, I had no issues compiling on Windows XP.   If you need me to up the number of source files I test trying to compile, I can.   I'd like to make sure it's high enough that we ensure there are no issues, but low enough that development of the plugin doesn't bog down.


davidB -

Would you mind making a release of the plugin as soon as you have the time?  I'm going to attempt to release a snapshot version so others can at least use this fix if needed.

Thanks,
-Josh

I deployed the 2.10-SNAPSHOTS on http://scala-tools.org/repo-snapshots/

Awesome! I need to remember you have Hudson building all this!

I'm hoping we can get arnaud's scala packaging/lifecycle into the 2.10
release. Do you have anything else you'd like to see in there?
