Is there a way to include all of these sub-dependencies > automatically, given that I already included netcdf? Yes, ---- THE SHORT ANSWER: To get a classpath with all the dependencies for your project run: mvn dependency:build-classpath ---- THE LONG ANSWER A) You can also just use Maven to run your test program. Here's some examples: 1) Without args mvn exec:java -Dexec.mainClass="Test" 2) With args mvn exec:java -Dexec.mainClass="Test" -Dexec.args="foo bar" 3) With runtime dependencies in the CLASSPATH mvn exec:java -Dexec.mainClass="Test" -Dexec.classpathScope=runtime B) Alternatively, if you want to build a executable jar or just dump all the dependencies into a directory, you should take a look at maven's assembly plugin. There's an example assembly descriptor at http://code.google.com/p/vcr4j/source/browse/trunk/src/main/assembly/download-bundle.xml C) Finally, If you just want to see what dependency's are used by your project run: mvn dependency:tree Cheers -- Brian Schlining
