Add maven-shade-plugin to pom.xml for Roo 1.2.0 throws error

[lsiu]

I have an interesting case where I migrate a Roo 1.1.5.RELEASE jar project to Roo 1.2.0.RELEASE. I was getting an

InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

error when Roo starts.

I created a new project and gradually migrate all the artifacts over and found that it was only when I add the maven-shade-plugin to the pom.xml file when I get the above error.

By simply adding the following:

			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-shade-plugin</artifactId>
			</plugin>

I will get the above error. Is there any way to turn on debug with Roo such that I can better troubleshoot this error and create a JIRA if necessary?

Update: 2011/12/27
It appeared there is a workaround by specifying the version of the maven-shade-plugin. For example, add

<version>1.5</version>

.
Not sure whether this is a bug, but this used to work find in ROO 1.1.5.RELEASE
