plugin dependencies issues

steffen

Hello folks,

I am currently developing a plugin using both the text-mining- and the weka-plugin. The dev-manual states, that  the field Plugin-Dependencies in the MANIFEST.MF-file should contain

A semicolon separated list of Extensions this Extension depends on

 

However, my plugin fails to load because of this rapidminer-core-method "Plugin#checkDependencies(List)".

if (pluginDependencies.size() > 1) {
			throw new UnsupportedOperationException("Only one dependent plugin allowed!");
}

Surely I can remove this line of code and recompile rapidminer, but I am afraid to break something/ curious to know WHY multiple dependencies are not allowed.

On a side note I noticed the following: If Plugin A depends on Plugin B, it is not necessarily given that B is loaded for A. B is of course available FOR A, when A is loaded, but the operators of B are NOT available FOR RAPIDMINER (=> e.g. in the OperatorService). I just wanted to check that this behaviour is also intended.

greetings and keep up the good work

Hi Steffen,

your observations are correct. For now, please enter only one dependeny. Multiple dependencies are currently not implemented, we'll re-add that soon.

Best,

Hello Simon

Thanks for the reply. I'll recompile rapidminer then and see what happens.
