UPDATE: Now I managed to get the <javac> task working by setting the "fork" attribute to "true". After the <javac> task I also have a <rmic> task, and now that one fails.
Message: Embedded error: Cannot use SUN rmic, as it is not available. A common solution is to set the environment variable JAVA_HOME or CLASSPATH. The <rmic> task has no fork attribute, so no analogous solution here :-( But this behaviour leads me to a new assumption: as this stuff used to run before yesterday, and as it still runs as a single module, have there recently been any changes on how maven treats environment variables in a reactor build? It seems that maven does not propagate environment to child modules, so the <rmic> task does not see JAVA_HOME, and thus does not find the rmic executable. How do I get around that?

Have there been made any changes to the maven-antrun-plugin or to how maven handles classpaths? Situation: I have a multi-module J2EE project. In the EJB module I compile an EJB client, not with the maven-ejb-plugin, as it doesn't fit my needs, but with the antrun plugin. It's just the usual Ant <javac> task. You can see the way I call the antrun plugin below, in the INPUT section. Now what is strange: when I cd directly to the module and then call "mvn clean compile", everything works fine. When I cd to the project top level directory and start a reactor build with "mvn clean compile", I get an error that Ant is "Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath." Why that??? Look at my debug echo message I've put into the ant script, the output is in the OUTPUT section. In the output you can clearly see that the last entry of the classpath is tools.jar, and yes, the location is correct. I'm desperate. Anyone any hints?
