Hi,

I'm using JDT to headlessly build an Eclipse workspace. This works fine expect for errors like the following being logged:

!ENTRY org.eclipse.core.resources 4 2 2016-06-11 00:05:15.164
!MESSAGE Missing resource filter type: 'org.eclipse.ui.ide.multiFilter'.

        at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

Is this a problem (in the sense that the build result differs when the filter is there)? Or is this filter merely used for UI purposes (meaning that I can safely ignore the errors in a headless scenario)?

Best wishes,

Andreas

Hi Andreas,

I too get the same issue. I did some debug and found out that this will not cause any issue, however this indeed is annoying in the log. So i have logged a Bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=503369

The main reason is in headless mode, we will not have ui plugins, but the implementation of org.eclipse.ui.ide.multiFilter is in 'org.eclipse.ui.ide'.

you can avoid by doing one of the below steps
1. Removing all the filteredResources in the .project file
2. you can have your own implementation copy by adding the extension point with same id 'org.eclipse.ui.ide.multiFilter' (Attached bundle, which can be directly used) in your product.

Note : the bundle attached should be only used in headless, as it is a copy of the original implementation.
