Description

I am in a need to add @Grab annotations to Grails BuildConfig file, in order to add jsch library to the classpath, because I need to declare SshResolver later in the config and this work charmingly from command line. Unfortunately, this makes Eclipse completely unusable, processor load gets to 100% and the compilation process hangs until Eclipse process eventually crashes. Here is the stack trace:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/reportfactory/grails-app/conf/BuildConfig.groovy: 6: Invalid duplicate class definition of class BuildConfig : The source /reportfactory/grails-app/conf/BuildConfig.groovy contains at least two definitions of the class BuildConfig.
One of the classes is a explicit generated class using the class statement, the other is a class generated from the script body based on the file name. Solutions are to change the file name or to change the class name.
 @ line 6, column 1.
   grails.war.resources = { stagingDir ->
   ^

By default STS Grails plugin includes grails-app/conf into project sources and my current workaround is to exclude it - after that Eclipse gets usable again.
