Bug 47729 Unable to ignore '*,D' files [filters]
I am using Aegis which produces files having the extension ',D', e.g. 'MyClass.java,D'. I want to ignore these files from being shown in the Package Explorer. I tried the filter in Project - Properties - Java Build Path - Source - Exclusion Filter but failed. I tried **/*,D **/*.java,D **/*.java?D without success. Seems as if this filter only ignores .java files. The only help I found was the filter for 'non-java elements', but then my .properties files disappear, too.
