Hi there,
I have a problem here that didn't occur until yesterday. 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?
Christoph
