ComponentCore.createComponent(project) (line 129) returns null
/*
@return A handle to an IVirtualComponent that may or may not exist or
* null if passed project does not contain ModuleCoreNature.
*/
ComponentCore#createComponent(IProject aProject, boolean checkForComponentFile)
So I expect the following nature could help:
<nature>org.eclipse.wst.common.modulecore.ModuleCoreNature</nature>
However, error handling in such a case is unacceptable. Expected: show dialog (or exception dialog) with information about missing nature.
I was able to get rid of the problem by adding of project nature <nature>org.eclipse.wst.common.modulecore.ModuleCoreNature</nature> and providing file .settings/org.eclipse.wst.common.component |
