Hello Fabian, Hello Matthias,
Thank you very much! I am not making API changes at the moment, so I
should be fine with this approach.
Unfortunately the command "mvn -DskipTests clean install" in the main
folder didn't work for me (it hanged in the middle of the operation), so
I am using a more brute force method. I compile the flink-runtime jar
file just as Fabian described and then use it to overwrite the content
in the "lib/flink-dist-0.9-SNAPSHOT.jar".
It is not really a clean path, but this method has reduced my compile
time down to 1 minute, which is a great improvement :)
Best,
Niklas

One more remark on this:
You need to be a little bit more careful. This approach works only, if
the initially changed module has no other dependent modules.
For example, flink-clients also depends on flink-runtime and thus, you
*might* need to rebuild flink-clients, too, before building flink-dist.
However, only if you did API changes in flink-runtime.
The basic message is, you need to understand the dependency tree. If you
did API changes, you need to rebuild all modules that depend on the
changed module.

Hi Niklas,
if you only want to update individual submodules you can do:
cd flink-runtime // build this submodule
mvn -DskipTests clean install // will put the new flink-runtime jar into
the local Maven repository
cd ../flink-dist
mvn -DskipTests clean install // will fetch all required dependencies from
the local Maven repository without rebuilding them.
You need to have run mvn -DskipTests clean install before to have all
required dependencies in the local repository.
Cheers, Fabian

Hi there,
I have a question on the setup of the development environment for flink.
Is it possible to update the big JAR file
(flink-dist/target/.../lib/flink-dist-0.9-SNAPSHOT.jar), which flink
apparently uses for deployment, with a single module (flink-runtime)?
Recompiling all of the modules takes several minutes on my laptop, while
compiling only the module is a matter of seconds.
My knowledge of maven is pretty limited, so I compile flink with
mvn package -Dmaven.test.skip=true
This process is really slowing down my development cycle. I would
appreciate your help :)
Best regards,
Niklas
