Hi Syed You could use 'mvn clean package -pl :flink-streaming-java_2.11 -DskipTests -am' to build flink-streaming-java and flink-runtime modules. If the 'already built binary' means the flink-dist-*.jar package, the former mvn command would not update the dist jar package. As far as I know, a quick solution is using `jar uf` [1] command to update the dist jar package with your changed classes. Otherwise, you need to build flink-dist module from scratch.

I already build the flink from source, now I am looking to build only a few modules which I have modified. Is this possible, or every time I have to build the flink in full (all modules). As it takes me about 30-35 minutes to build the flink in full. Specifically, I have modified some classes in *flink-streaming-java* and *flink-runtime* modules. I am looking to build only these two modules and integrate these into already build flink (all modules). I alrady tried using –pl option using mvn, it installs these modules but changes are not updated in already build binaries. Please guide me how can I do this. Kind regards; syed -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
