I've been looking for answers for 2 days, haven't found anything. someone please help me out.

so I was following this Tutorial link text trying to build the ros_core. but every time I come to step 4, the same error comes up.

evelyn@evelyn-VirtualBox:/opt/ros/electric/stacks/rosjava_core/rosjava_bootstrap$ rosrun rosjava_bootstrap install_generated_modules.py rosjava

I guess this is a maven issue. but I don't know how to solve it. using mvn --version I get the following feedback:

Apache Maven 3.0.4 (r1232337; 2012-01-17 09:44:56+0100)
Maven home: /usr/local/apache-maven/apache-maven-3.0.4

Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.38-13-generic", arch: "i386", family: "unix"

btw the reason why I'm building up ros_core is that I want to get the newest version of rosjava jars, so that I can finally follow the codes and tutorials. Anyone knows whether I can download them somewhere? is there a rosjava library?

You should not try to build rosjava from your /opt directory. It's likely that you do not have permission to generate code there. Instead, install rosjava from a ROS workspace directory in your home directory (for example).
