It seems as if this version requires more rights than the ones before. Here is the Console output:

mirkojahn:

I tried it with 1.341 again and everything worked perfectly. I haven't tried the versions in between though. Hope that helps a little.

[timja]

kohsuke:

I don't have a Mac to test this handy, but the root cause of the problem is that your Maven process cannot communicate with the current window station. You can work around this by adding "-Djava.awt.headless=true" to your MAVEN_OPTS.

I'm not sure if it's at all possible for Hudson to do this for you without causing some issues in other situations.

[timja]

kohsuke:

The only remaining issue is if it's possible for Hudson to set this system property on behalf of the user. Changing the issue to reflect this.

[timja]

mirkojahn:

Well, maybe it is not necessary to specify this for all Mac instances. If you take a look at the environment, you'll see that I had to define "CATALINA_OPTS=-server -Djava.awt.headless=true -Xmx512m" anyway. So the tomcat (in my case) already knew how to get started. I think it would be best to just take the options already passed to the running JVM as input for the spawned process (as done for -Xmx already - as it seems). With this, the "fix" is not limited to any OS, but on the general configuration of the server.

[timja]

mirkojahn:

Another thing that puzzled me is the fact, that it worked in version 1.341. So something must have changed in order to require "java.awt.headless=true".

rpomeroy:

I'm on a Mac deploying to Virgo (Tomcat) M03 and I get an icon in the doc which tells you something thinks it needs a window server. This wasn't the case deploying 1.3x on Virgo (Tomcat) M02 or M03. Launching war from the command line doesn't result in a dock icon for either. Adding -Djava.awt.headless=true does indeed eliminate the dock icon - but I too would like to know where a dependency on AWT or Swing code creeped in. I don't want to have to mod Virgo for every deployment. Time to explore the code.

[timja]

rpomeroy:

One other thing - this is a Jenkins out of the box - before configuring the Maven runtime.

[timja]

josht:

I was able to work around this issue by adding the -Djava.awt.headless=true to the JVM Options of the (Advanced) Launch Method section of the build slave configuration.

Thank you for the workaround, Joshua.
