Description

Running the following code:

@GrabResolver(name='jboss', root='http://repository.jboss.org/maven2')
@GrabResolver(name='codehaus.snapshot', root='http://snapshots.repository.codehaus.org')
@Grab(group='org.codehaus.gpars', module='gpars', version='0.9-beta-1')
import groovyx.gpars.actor.PooledActorGroup

println new PooledActorGroup()

Gives the following error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/Users/tyates/Code/Groovy/chat/chatserver.groovy: 3: unable to resolve class groovyx.gpars.actor.PooledActorGroup
 @ line 3, column 1.
   @GrabResolver(name='jboss', root='http://repository.jboss.org/maven2')
   ^

1 error

If I move the GrabResolvers off to a different member, ie:

@GrabResolver(name='jboss', root='http://repository.jboss.org/maven2')
@GrabResolver(name='codehaus.snapshot', root='http://snapshots.repository.codehaus.org')
def dummy() {}
@Grab(group='org.codehaus.gpars', module='gpars', version='0.9-beta-1')
import groovyx.gpars.actor.PooledActorGroup

println new PooledActorGroup()

Then the error changes to:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/Users/tyates/Code/Groovy/chat/chatserver.groovy: 3: Cannot specify duplicate annotation on the same member : GrabResolver at line: 3 column: 1. File: /Users/tyates/Code/Groovy/chat/chatserver.groovy @ line 3, column 1.
   @GrabResolver(name='jboss', root='http://repository.jboss.org/maven2')
   ^

1 error

To get this to work, I need to do the following:

@GrabResolver(name='jboss', root='http://repository.jboss.org/maven2')
def dummy() {}
@GrabResolver(name='codehaus.snapshot', root='http://snapshots.repository.codehaus.org')
def dummy2() {}
@Grab(group='org.codehaus.gpars', module='gpars', version='0.9-beta-1')
import groovyx.gpars.actor.PooledActorGroup

println new PooledActorGroup()

which then gives the output:

groovyx.gpars.actor.PooledActorGroup@2f2c55e4

So it seems there may be two problems currently:

1) You cannot specify multiple GrabResolvers for a single member
2) You cannot specify GrabResolvers on import statements

---

To check that 2 fails, I tried the following:

@GrabResolver(name='restlet.org', root='http://maven.restlet.org')
@Grab(group='org.restlet', module='org.restlet', version='1.1.6')
import org.restlet.data.MediaType
import org.restlet.resource.StringRepresentation

println new StringRepresentation( "Hi", MediaType.TEXT_PLAIN )
