Building some specific modules in flink

[syed]

Hi;
I am trying to modify some core functionalities of flink for my through
understanding about flink.  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

You need to specify flink-dist in -pl. Module flink-dist will build the flink binary distribution.

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.
