Here is a command that will compile and jump to the line of the file with the error:

Before running command: Do nothing Command: cd [directory where build.xml is located]; ant [your target to build source]; Standard Input: None Standard Output: Show in separate window Pattern: .*/(\w*.java):(\d+):(.*) Format String: $1 $2 $3 File register: 1 Line: 2

Someone can improve on this to get the column and more error information too. That would be nice.
