Ok, some progress:
If I remove the Scala plugin and instead add
configurations {
scalaTools
}
in the beginning and
task compile {
ant.taskdef(resource: 'scala/tools/ant/antlib.xml', classpath:
configurations.scalaTools.asPath)
ant.mkdir(dir: "build/classes/main")
ant.scalac(srcdir: "src/main/scala/", destdir: "build/classes/main",
classpath: configurations.compile.asPath)
}
in the end, everything works as expected!
So I'm wondering how the Scala plugin calls the ant task and what has
changed between Scala 2.7.7 and 2.8.0??
Any hints as how to proceed?
