Unable to Build on Ubuntu 12.04 Instance

(I'm forwarding this request from Ketan Maheshwari, one of the developers on the Chicago side of things.)

In a clean download of ACMO on Ubuntu 12.04 running in AWS, mvn install fails, and outputs:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project acmo: Compilation failure: Compilation failure:

This is using both Java 6 and 7. Any thoughts?

Jeremy and Ketan,

It might be the version of Maven being used (Maven 2 vs Maven 3)? Another issue could be how the maven file is working. I can look into it, but it you could send the whole -X maven debugging log, that would help.

Thanks,

Chris V.

After further investigation, I realized that the pom.xml has a version
requirement but does not implement it in the settings. Maven seems to be
using an older version of Java (since it calls it's own Java instance).

Oh, er... okay- how do we fix it?

[frostbytten]

The fix should be applied in the develop branch.
