mule - Issues with devkit 3.3.2 and eclipse CoreException -

i trying create connector in mule studio 3.4 using devkit 3.3.2.

the following maven (3.0.2) command used generate project structure:

$ mvn archetype:generate -darchetypegroupid=org.mule.tools.devkit   -darchetypeartifactid=mule-devkit-archetype-cloud-connector   -darchetypeversion=3.4.0 -dgroupid=org.hello -dartifactid=hello-connector   -dversion=1.0-snapshot -dmuleversion=3.4.1  -dmuleconnectorname=hello  -dpackage=org.hello  -darchetyperepository=http://repository.mulesoft.org/releases 

after this, did:

"mvn clean package -ddevkit.studio.package.skip=false -dskiptests" 

this gave errors in studio seem related devkit 3.4.0, therefore decided change mule/devkit version 3.4.0 3.3.2 in pom.xml:

<mule.version>3.3.2</mule.version> <mule.devkit.version>3.3.2</mule.devkit.version> 

the following 2 errors shown in studio:

"the project not built since build path incomplete. cannot find class file org.eclipse.core.runtime.coreexception. fix build path try building project aria-connector unknown java problem"

and

"the type org.eclipse.core.runtime.coreexception cannot resolved. indirectly referenced required .class files ariaactivator.java /aria-connector/target/generated-sources/mule/org/mule/tooling/ui/contribution line 1 java problem"

my environment mac os x 10.8.4 (error appears in windows 7 too), mule studio 3.4.0, java version "1.6.0_51".

has encountered similar issue or have idea how resolve please?

thanks
