Hi, Christian,
The ./gradlew command to publishToMavenLocal should be executed from the
checkout location of the Samza project, not hello-samza. The tutorial page
stated that (from the snippet I copied). Maybe we should make this more
obvious in the first step: you will need to checkout *both* samza and
hello-samza repositories if you are working on the latest branch in
hello-samza. There is a JIRA open that we are trying to combine those two
together, but for now, those two repositories need to be checked out
separately and the working combinations are the following:
- samza latest release branch (e.g. 0.10.0) + hello-samza master. In this,
hello-samza master can work out-of-box since all Samza artifacts it needs
are published and available in the public maven repository
- samza master branch (e.g. currently 0.10.1) + hello-samza latest. In this
combination, hello-samza latest do not work out-of-box by itself and needs
the companion samza master build (i.e. the publishToMavenLocal build
command) to make the latest unpublished samza artifacts become available in
local box.
Did you try: a) checkout the samza repository in a different directory; b)
cd to samza directory and run ./gradlew publishToMavenLocal; c) switch back
to hello-samza directory latest branch and run the maven build? If the
above sequence does not work, please let me know the errors you saw.
Alternatively, you can try to run hello-samza master branch, which will
automatically pulling in samza artifacts from public maven repo and skip
the above steps a) and b).
Thanks for making the effort to create an out-of-box docker image for
hello-samza!
Cheers!
-Yi
