Hi Tommy, I've run into some problems along these lines, but in my case, it only happens when I build first using Maven and then try to recompile in the IDE. The problem appears to be that the two disagree on where the generated classes go (there was a change in one of the JDK releases, I believe).
I work around that by doing a clean compile in maven before starting IDE work. Is that your problem? Or are you only seeing this by only doing repeated Maven builds? I don't have that problem. - Russ On Jul 19, 2013, at 11:22 AM, Tommy Svensson <to...@natusoft.se> wrote: > Hello, > > I have found a problem when using auto triggered annotation processors > (META-INF/services/javax.annotation.Processor) with maven builds!
