Question

How could I configure a Grails application in a way that run-app and war would take into account some external source path ../external/src?

I’d like not creating a separate grails plugin for that.

UPD. Thanks to Ian Roberts, there is a solution. But there is an additional wish appeared. I want that external source (which is large enough) would be used for searching for missed classes only. Not like everything from there is put into the *.war now. (That could be achieved with a jar optimizer at least.)

The list of source directories to be compiled is a property of the projectCompiler, which you can add to in a suitable _Events.groovy block. Try this:

eventCompileStart = {
  projectCompiler.srcDirectories << "${basedir}/../external/src"
}
