Created attachment 93764 [details] A test project [recent builds] Steps to reproduce: 1. Download the attached project, unpack, open in the IDE. 2. Build the project 3. Build tests for the project (ant test-build from the cmd. line), take a look at the generated layer at: aptest/build/test/unit/classes/META-INF/generated-layer.xml 4. Touch o.n.aptest.Test1.java, build tests again (ant test-build) 5. Check the layer. The layer contains duplicated comment referring o.n.aptest.Test1 - repeating step 4 will produce more of these comments. Although this may look like a minor problem, it may cause major problems in massively incremental environments, like NetBeans indexing. For example, the generated-layer.xml for java.hints has currently around 200KB, but I have seen a more than 3MB layer produced by the IDE.
This is probably for me.
Was unintentional, and happened only for the rarer case of folders being generated directly using .folder(). (In most cases <folder>s are generated indirectly using .file(), which creates intermediate parent folders as needed but does not add any comment about the origin.) core-main #ccf1426567d9
Integrated into 'main-golden', will be available in build *201002040200* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main/rev/ccf1426567d9 User: Jesse Glick <jglick@netbeans.org> Log: #180154: do not duplicate comments after an incremental build.
