[osmosis-dev] Osmosis plugin development and integration tests

[Nicolas Colomer]

Hi Brett and thank you a lot for your answer,

Your guidance helped me solve the problem!
FYI, I am using Maven as dependency and build system.

For future readers, here is how I did:

   - Make sure needed Osmosis modules are in your classpath (for instance,
   the osmosis-core-0.41.jar)
   - Add module's external dependencies (for instance, those extracted from
   core's build.gradle<https://github.com/openstreetmap/osmosis/blob/master/core/build.gradle>
   ):
      - net.sf.jpf:jpf:1.5<http://search.maven.org/#artifactdetails%7Cnet.sf.jpf%7Cjpf%7C1.5%7Cjar>
      - org.codehaus.woodstox:woodstox-core-lgpl:4.1.4<http://search.maven.org/#artifactdetails%7Corg.codehaus.woodstox%7Cwoodstox-core-lgpl%7C4.1.4%7Cjar>
      - org.codehaus.woodstox:stax2-api:3.1.1<http://search.maven.org/#artifactdetails%7Corg.codehaus.woodstox%7Cstax2-api%7C3.1.1%7Cjar>
      - org.apache.commons:commons-compress:1.4.1<http://search.maven.org/#artifactdetails%7Corg.apache.commons%7Ccommons-compress%7C1.4.1%7Cjar>
      - xerces:xercesImpl:2.9.1<http://search.maven.org/#artifactdetails%7Cxerces%7CxercesImpl%7C2.9.1%7Cjar>
   - Add an osmosis-plugins.conf file in your classpath, with namespaces to
   your PluginLoader(s)
