Questions about flink-streaming-examples

Hi,

I tried to build flink-streaming-examples, but got an compilation error.
If I build flink-streaming (that implicitly builds
flink-streaming-examples), it works.

I tried it on a fresh clone of flink/master using "mvn clean compile
test-compile"

Can anybody explain this behavior?

Yes. Builds fine here too..
Seems like some linking errors..

Re: Questions about flink-streaming-examples

Posted by Till Rohrmann <tr...@apache.org>.

If the streaming-examples module uses the <classifier> tag to add the
test-core dependency then we should change it into <type> tag as
recommended by maven [1]. Otherwise it might come to build failures if the
install lifecycle is not executed.

The dependency import should look like:

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-streaming-core</artifactId>
  <version>${project.version}</version>
  <scope>test</scope>
  <type>test-jar</type>
</dependency>

Re: Questions about flink-streaming-examples

Posted by "Matthias J. Sax" <mj...@informatik.hu-berlin.de>.

Thanks for clarifying Marton!

I was on the latest build already. However, my local maven repository
contained old jars. After removing all flink-jars from my local maven
repository it works!

Why does maven no automatically update the local repository?

Re: Questions about flink-streaming-examples

Posted by Márton Balassi <mb...@apache.org>.

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flink-streaming-examples and you might have used an outdated version of the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

Re: Questions about flink-streaming-examples

Posted by "Matthias J. Sax" <mj...@informatik.hu-berlin.de>.

Hi,

I just build "flink-streaming" and avoid the problem. I guess, that the
issue is related to the module structure and dependencies.
"flink-streaming-examples" uses
org.apache.flink.streaming.util.StreamingProgramTestBase (that is
defined in "flink-streaming-core/src/TEST"

From my understanding, maven does not support dependencies into src/test
but only into src/main (maybe I am wrong about this).

I would suggest, to move StreamingProgramTestBase into a new module
"flink-streaming-testUtils" (into src/main) and change the dependency of
flink-streaming-examples accordingly.

Why the build work on the parent-project, is still a riddle to me... But
it seems that the dependency into scr/test can be resolved for this case.


-Matthias

Re: Questions about flink-streaming-examples

Posted by "Matthias J. Sax" <mj...@informatik.hu-berlin.de>.

it might be a good idea to have a look into it IMHO.

Re: Questions about flink-streaming-examples

Posted by Stephan Ewen <se...@apache.org>.

Hi Matthias!

Can you try "mvn clean package"? It package is generally preferable to
compile, in my opinion.

There may be a dependency through a test jar that is not properly handled
when you do not execute the package goal.

Re: Questions about flink-streaming-examples

Posted by Max Michels <mx...@apache.org>.

flink-streaming-examples using "mvn clean compile test-compile" and it
worked.

Best regards,
Max
