Create and run an Apache Stanbol instance - fails

Following the instructions: stanbol build and start the instance of stanbol

We always get the following error on execution:

% mvn clean install

[ERROR] The target org.apache.maven.plugins: maven-surefire-plugin: 2.16: test (default test) in the org.apache.stanbol.commons.owl project failed: there are testing errors.

We assume this has something to do with this:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: default for inactivity (NOP) SLF4J: For more information see http://www.slf4j.org/codes.html#StaticLoggerBinder .

Full log can be found: here

Since we don’t know what exactly went wrong, we hope that someone can give us some advice to find a solution.

If tests are skipped with -DskipTests

If after that a server error message appears:

16.07.2014 12:30:10.136 *ERROR* [FelixStartLevel] ERROR: Error starting

Access the full server log here

The result that I get when using stanbol 0.12 here is still an error, but most of the tests were successful ... the version on github has a similar error here

And starting after skipping tests throws it. Errors are shown here.

The workaround is to skip tests, just add “-DskipTests” when calling maven. The real solution would probably be to add the slf4j implementation in test mode in commons / owl.
