Robocode / Forums / Help / Help: Error building from Eclipse, but everything seems fine.

OS: Win 7

Hello,

I'm trying to create a version of Robocode for use in a classroom environment, but when I attempt to run Robocode form Eclipse to edit the sources, I get the following error after I press run as Robocode:

'Launching Robocode' has encountered a problem.
Variable references non-existent resource : ${workspace_loc:robocode.api/target/launch}

I've done and redone the steps in the developers guide, but it hasn't worked for me yet. The error I get in Eclipse is a reoccurring problem for me. One other user posted on the forum with the same error message and I made sure to follow the directions in that post (use JDK 6) but still no luck. The only thing I can think of being the culprit is having set the Maven environment variables to M3_HOME and M3 rather than M2 and M2_HOME, which had previously not allowed Maven to run correctly.
Anyways, here are my Maven and Java version printouts:

C:\Users\[user]\git\robocode>java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)



C:\Users\admin\git\robocode>mvn -version

Similarly, nothing seems wrong when I run mvnassembly while within C:\Users\admin\git\robocode, and same with mvn clean install.
