[API] Java API: How do I add dependencies to the classpath?

[feli74]

Hi,

where do I need to drop my dependencies (eg log4j) in order for the extension classloader to find them?
I tried creating a fat fat using maven shade, but I still get NoClassDefFoundError exceptions.

thanks,
felix

Can you post your pom.xml?

You need to run the shader before the copy plugin.
