Description

Let the issue 1 identified in NETBEANS-4938 live here.

 

Issue number 1 is much harder and requires a good knowledge on how the Lookup system works.

So the Lookup of NBGradleProjectImpl consists of a basic lookup created at: https://github.com/apache/netbeans/blob/3a2cad159a2a60665653ce83a67547f6744449ec/extide/gradle/src/org/netbeans/modules/gradle/NbGradleProjectImpl.java#L161 and a plugin dependent ProxyLookup at https://github.com/apache/netbeans/blob/3a2cad159a2a60665653ce83a67547f6744449ec/extide/gradle/src/org/netbeans/modules/gradle/NbGradleProjectImpl.java#L330

 

The issue is the following:

1. Project loads with no plugins, the base set of lookups registers a SourcesMerger
2. Initially the only Sources implementation is for GENERIC_SOURCE_TYPE for the project folder.
3. On reload through the PluginDependentLookup a new Sources implementation become available org.netbeans.modules.gradle.java.classpath.GradleSourcesImpl from the Gradle Java project
4. Unfortunately the SourceMerger is not pick up the new Sources implementations
