Hi all,
i figured out a NullPointerException, while i try to run a
transformation via API from an export wizard. A weird thing is, that
running the transformation from within the eclipse test application (run
as -> eclipse application), it works properly, but after the
installition of the builded plugins via update manager, i get the
following stack trace:
-----------------
java.lang.NullPointerException
at
org.eclipse.core.internal.runtime.Activator.getURLConverter( Activator.java:313)
at org.eclipse.core.runtime.FileLocator.toFileURL(FileLocator.j ava:205)
at
de.fraunhofer.fokus.testing.m2t.xml.modelplex.sap.files.Gene rateTestCase. <init>(GenerateTestCase.java:133)
at
de.fraunhofer.fokus.testing.mbttool.export.sap.wizards.SAPTe stScriptExportWizard.performFinish(SAPTestScriptExportWizard .java:90)
at
org.eclipse.jface.wizard.WizardDialog.finishPressed(WizardDi alog.java:752)
-----------------
The code snippet looks like this:
if (EMFPlugin.IS_ECLIPSE_RUNNING) {
templateURL =
FileLocator.toFileURL(GenerateTestCase.class.getResource(MOD ULE_FILE_NAME
+ ".emtl"));
.....
I'm pretty sure, that this is a Acceleo related problem, since the
exception occurs in a generated code snippet of Acceleo.
So, what's wrong with the transformation?!
Cheers Timothy

Hi Timothy,
We currently have problems with headless builds; in short, the jdt java
compiler deletes all emtl files and we cannot recompile them anew
_after_ its passage.
Using the "export as => deployable plugins and fragment" wizard should
work as expected, yet headless builds won't work atm.
How do you export your generator projects as plugins? And could you
raise a bug with a project that presents this bug (more test cases are
always welcome)?
