Errorformat for maven3 in vim

Question

I'm running maven 3 from vim and I'm partially successful in getting the error format defined. Here's what I have now:

makeprg=mvn compile -q -f pom.xml

errorformat=[ERROR]\ %f:[%l%.%c]%m

Maven3 build error:

    :!mvn compile -q -f pom.xml  2>&1| tee /var/folders/qy/qyYtxIV9EECvBoYr30SmkU+++TM/-Tmp-/vemUiQM/6
[debug] execute contextualize

The problem now is that I get additional, unnecessary lines in my quickfix list:

|| [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.1:compile (default-compile) on project org.wso2.carbon.bam.clustermonitor.ui: Compilation failure: Compilation f#

 16 || [ERROR] For more information about the errors and possible solutions, please read the following articles:

How do I tune the error format better to get only the errors to appear in the quick fix list?

Answer 1

I found a working Maven 3 errorformat here:

set errorformat=[ERROR]\ %f:[%l\\,%v]\ %m

Answer 2

Read up on :help errorformat-multi-line and :help efm-ignore. It's also helpful to investigate how other compiler plugins define their 'errorformat'.
