Bear in mind that if you accept this pull, modeller project will most likely fail - as it depends on PDI for its libraries (that's why the in place fix - pull 205 - has been reverted).
To fix this failure one would need to add the following libraries as the modeller dependencies :
<dependency org="org.mvel" name="mvel2" rev="2.0.10" transitive="false"/>
<dependency org="org.eclipse.jdt" name="core" rev="3.4.2.v_883_R34x" transitive="false"/>
and potentially the drools if the two above will not be enough:
<dependency org="org.drools" name="drools-api" rev="5.0.1" transitive="false"/>
<dependency org="org.drools" name="drools-core" rev="5.0.1" transitive="false"/>
<dependency org="org.drools" name="drools-compiler" rev="5.0.1" transitive="false"/>
These are the libraries that have been moved into plugin.
