How to install plugins in notes 8.5.1

Does anybody know how to install eclipse plugins into 8.5.1?

By our experience Notes 8.5 (better: Expeditor) has too many customized features, so eclipse based plugins couldn’t be installed.

(

eg: error during eUML2 installation:

Current configuration contains errors that are not corrected by the requested operation and more errors would be introduced. See details for more information.

----- Current configuration problems -----

Eclipse Platform Components (6.2.1.20090909-1600) requires feature "org.eclipse.platform.feature (3.4.2)", or compatible.

----- Configuration problems after the operation -----

Eclipse Platform Components (6.2.1.20090909-1600) requires feature "org.eclipse.platform.feature (3.4.2)", or compatible.

EMF - Eclipse Modeling Framework Runtime and Tools (2.4.1.v200808251517) requires feature "org.eclipse.platform (3.3.0.v20061208-Fj22sCYGm0XDWm3)", or compatible.

Graphical Modeling Framework Runtime (1.1.2.v20080916-2008-7c7a7REWvhKvgc1pKGmabT8ukFgQ) requires feature "org.eclipse.platform (3.3.0)", or compatible.

)

looking into the Expeditor features shows that ther are many or.eclips.xy plugins are replaced by some com.ibm.xy plugins.

So, I fear that “normal” Eclipse plugins couln’t be installed.

Has anyone a deeper look inside this? Has anybody any magic ‘workarounds’ ?
