Comment 2 hstenger 2013-10-09 15:32:04 UTC
I can reproduce this under Linux with 7.4 RC2. I found out it is the layer.xml file which triggers the AssertionError when the application loads a module from the jar file as well as the target/classes directory. The layer.xml file is then contained twice in the module. I have created a minimal example to demonstrate this behaviour (see costest.zip). Steps to reproduce: 1. Open project in NetBeans IDE. 2. Use "Clean and Build" on costest-parent. 3. Modify a source file, e.g. add a line break in the layer.xml file in costest-core. 4. Use "Run" on costest-app. Work-around: Disable Compile on Save on *all* dependent projects of the application.

Comment 5 Milos Kleint 2013-10-11 09:51:33 UTC
does upgrading the application to use netbeans 7.4 fix the problem? I believe it should be enough to disable Compile on Save on the application project.
Comment 6 hstenger 2013-10-16 13:59:00 UTC
Upgrading the application to RELEASE74-BETA does not help. I cannot see RELEASE74 in the NetBeans repository yet. Disabling Compile on Save for the application project was actually the first thing I tried. Sorry for not mentioning this earlier. However that does not seem to affect the behaviour at all. Is there a way to disable Compile on Save globally? I searched in the options window and the menus but could not find anything.
Comment 7 Milos Kleint 2013-10-17 08:35:01 UTC
indeed, we were missing a check for CoS in the application project. following changeset fixes that. Unfortunately for 7.4 FCS the only workaround is to either upgrade the platform to 7.4 (will be up shortly) or disable compile on save on all module projects. That can be done globally by adding the <netbeans.compile.on.save>none</netbeans.compile.on.save> property to an activated profile in ~/.m2/settings.xml. A likely candidate for a patch release backport. http://bits.netbeans.org/nexus/content/repositories/release74
Comment 8 Tomas Danek 2013-11-05 14:47:58 UTC
Which changeset would you like to backport to 74patch1? I can confirm that changing to RELEASE74 fixes the problem that sample from comment #2 demonstrate in NetBeans 7.4 and Dev 20131104. However without modifying to RELEASE74 this does not work.

Comment 9 Milos Kleint 2013-11-06 06:18:09 UTC
http://hg.netbeans.org/core-main/rev/e3fffe7e2aec to be able to disable just CoS on the application. With CoS turned on the problem will still appear for some/many modules that work on top of pre 74 platform.
