I am developing an application on top of Eclipse utilizing JET.
My JET Transformation XML file looks like below-

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<inits id="N09FE010088811E9BBD787A845960DD4"
type="com.deepanwita.org.test.ft.aftsuite">
<group>
<tests>
<test path="/MyProject/test1.testsuite" />
</tests>
<browsers>
<browser name="chrome" />
</browsers>
</group>
</inits>

When I try to run the above XML using run button, I get bellow error-
java.lang.NullPointerException
at org.eclipse.jet.internal.launch.JET2TransformationDelegate.internalGetReferencedProjects(JET2TransformationDelegate.java:138)
at org.eclipse.jet.internal.launch.JET2TransformationDelegate.getReferencedWorkspaceProjects(JET2TransformationDelegate.java:104)
at org.eclipse.jet.internal.launch.JET2TransformationDelegate.getBuildOrder(JET2TransformationDelegate.java:84)
at org.eclipse.debug.core.model.LaunchConfigurationDelegate.saveBeforeLaunch(LaunchConfigurationDelegate.java:261)

at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:840)
at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:739)
at org.eclipse.debug.internal.ui.DebugUIPlugin.buildAndLaunch(DebugUIPlugin.java:1039)
at org.eclipse.debug.internal.ui.DebugUIPlugin$8.run(DebugUIPlugin.java:1256)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:56)

I have two options

Either handle null pointer Exception(better giving customed informative message) or
Disable the run button while XML editor is opened

Please guide me. Thanks

Hi

I think there is a misunderstanding. JET is an M2T tool. It does not take an XML input, so I suspect that you are doing something a bit crazy and that is what the NPE is telling you.
