Dear Mathias,
Thanks for reporting the issue. I have successfully built
flink-streaming-examples with maven, you can depend on test classes, the
following in the pom does the trick:
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-streaming-core</artifactId>
<version>${project.version}</version>
<scope>test</scope>
<classifier>tests</classifier>
</dependency>
This tells maven that the test classes of the examples (scope) might depend
on the tests of the core (classifier). Without explicitly stating the tests
classifier indeed maven only uses the classes under src/main.
I think the problem occurred because you only built
flink-streaming-examples and you might have used an outdated version of the
flink-streaming-core as a dependency installed to your local maven
repository - which did not include the StreamingTestBase yet. The change
that we are talking is about a week old, I wrote it.
Kind regards,
Marton
