             Summary: Multi-thread Flink compilation
                 Key: FLINK-20092
                 URL: https://issues.apache.org/jira/browse/FLINK-20092
             Project: Flink
          Issue Type: Bug
            Reporter: Maciej Bryński


I'd like to use maven -T option when compiling flink.
{code:java}
 mvn -T 2C clean install -D"scala-2.12" -DskipTests{code}
Unfortunately my build is stuck on:

{code}
Can we make flink compilation working with multiple maven threads ?
