I am having trouble configurating Eclipse for MD 18.3 plugin development.
I have thoroughly followed the "MagicDraw 18.3 Developer Guide / Development in Eclipse" tutorial you can find inside MagicDraw\openapi section to set up Eclipse.
When launching MagicDraw with all plugins run configuration, it throws the following error and terminates:
!ENTRY org.eclipse.core.variables 4 120 2016-07-20 10:39:12.159
!MESSAGE Reference to undefined variable file_uri
caused by this line of the run configuration
-Dosgi.framework.extensions=reference:${file_uri:${workspace_loc:/MagicDraw/MAGIC_DRAW_INSTALL_DIRECTORY/lib/bundles}}/com.nomagic.magicdraw.osgi.fragment
However, \lib\bundles\com.nomagic.magicdraw.osgi.fragment_1.0.0.201601271815.jar is existing
I'm running the demo license, but that shouldn't influence the configuration. Any suggestions?
UPDATE
Solved this issue, by replacing reference:${file_uri:${workspace_loc:/MagicDraw/MAGIC_DRAW_INSTALL_DIRECTORY/lib/bundles}}/com.nomagic.magicdraw.osgi.fragment with the actual path and enabling com.nomagic.magicdraw.platform.feature in the bundles tab of the run configuration.
Next Problem: The provided example plugins won't load, throwing
java.lang.NullPointerException at com.nomagic.magicdraw.plugins.XMLPluginDescriptorLoader.loadPluginDescriptorData(XMLPluginDescriptorLoader.java:172)
and therefore
ERROR PLUGINS - Failed to create plugin: My Plug-in 2
java.lang.ClassNotFoundException: myplugin2.MyPlugin2
Same message for both, the example plugins and my own plugin. I have checked the plugin.xml files and also experimentally enabled the run configurations > bundles > workspace checkbox.
Setting up a new clean Eclipse installation solved everything.
