As part of my Eclipse plugin project I need to track additions, deletions and changes to methods in order to implement the functionality I'm after. By registering a listener through JavaCore.addElementChangedListener and recursively traversing the IJavaElementDelta until the IJavaElementDelta.getElement() gives a reference to an affected method, I am able to capture method additions and deletions. E.g. I add method a into class B I get: [Working copy] B.java[*]: {CHILDREN | FINE GRAINED | AST AFFECTED} B[*]: {CHILDREN | FINE GRAINED} a()[+]: {}] The problem is that this does not take place

I am experienced with Eclipse 3.x development and now want to develop an E4 application. Therefor I tested a simple example in order to get started with the new things. I was following this tutorial step by step but it results in the same error. However, he is not getting those errors. I'm using Eclipse Luna (4.4.2) and installed the E4 Tools (0.17) . I've created a new Eclipse 4 Application and added to the Application.e4xmi the Common Resource Navigator (Project Explorer) as Shared Part using Import 3x -> View as CompatibilityView. I then added a Placeholder which references the shared part.

i am having trouble with custom quick-fixes, which i want to provide in my Eclipse plug-in, and i'm hoping for someone more experienced than me in Eclipse PDE to have some hints for me on this issue. As i have understood, i can provide custom so-called "quick fixes" (or "resolutions", in Eclipse inside terminology), by extending the extension point org.eclipse.ui.ide.markerResolution for a specific marker id, such as for example some default Eclipse marker, org.eclipse.core.resources.problemmarker . This works for me for the default marker types and for custom marker types, BUT : The

I'm using a target definition that references a P2 update site. Update site was updated recently with a plugin that has same version and qualifier as previous version, but different content. I've deleted .metadata/.plugins/org.eclipse.pde.core and tried resolving and applying target definition again. Strangely, target definition recreates previous version of plugin in .metadata.plugins\org.eclipse.pde.core.bundle_pool (I'm checking its content and behaviour) Where could the content be cached and how do I flush this cache? Version: Kepler Service Release 2 Build id: 20140224-0627 Update site

Having implemented one of the above, can anyone say how I might wire it up directly to a viewer? None of the usual sources explain. Martin. JB. As far as I can tell you need an ILabelDecorator and the only easy way to get one is to use the workbench UI: viewer.setLabelProvider( new DecoratingLabelProvider(new MyPlainLabelProvider(), PlatformUI.getWorkbench().getDecoratorManager().getLabelDecorator())); You then need to add your lightweight decorator to the decorators extension point in the plugin.xml . Obviously, this will only work if your app is an Eclipse plugin. It seems odd that

I'm developing an editor plugin for eclipse. It works fine on files within eclipse projects, but when an external file is opened via the "File -> Open File" menu (which works file with, e.g. Java files), I get a page displaying nothing but a horizontal blue line and the word "ERROR". The Error Log of eclipse is empty, as is the log file in the .metadata directory. What could cause this? How can I diagnose the error when I have no error message that tells me where to look? There doesn't seem to be a way to get more detailed logging from eclipse. Edit: I've found that the source of the problem
