maven provided dependency will cause NoClassDefFoundError in intellij?

IntelliJ doesn't seem to put the provided dependency on the classpath when I run it, however I can do this successfully in Eclipse.
As it would be a lot more convenient for me, how can I do this in IntelliJ?

IntelliJ now has an option to Include dependencies with provided scope in the Run Configuration:

Any library marked as scope - provided means that the library (as the name suggests) is supposed to be provided by the JDK or the container (e.g. tomcat) at runtime.

I'm having the same problem. Intellij does not include provided dependencies in classpath. See this source. The best solution I found is to run it as maven app, using the exec:java goal. For example:

exec:java -Dexec.classpathScope=compile -Dexec.mainClass=com.splout.db.integration.NShardEnsemble -Dexec.args=4

Better solutions are welcome.

Does it work in Maven via command line? The behaviour seems correct. Eclipse used to handle classpath badly, so I guess it still does.

There is a difference if you run something in Test source root or Source root, since the scope provided is only available on the compilation and test classpath.

If you run a test, or a main method in Test source root, then it can use provided dependencies, but if you try to execute something (via IntelliJ, or exec-maven-plugin) in Source root, then it will fail on ClassNotFoundException.
