Seems that I made a stupid copy-paste mistake - m2e-wtp has osgi bundle "org.eclipse.m2e.wtp", but in our case should be "com.mountainminds.eclemma.core" instead of "com.mountainminds.eclemma":
requires.0.name=com.mountainminds.eclemma.core units.1.id=com.mountainminds.eclemma.core units.1.provides.0.name=com.mountainminds.eclemma.core So excuse me for a noise - all seems to work fine after this fix. Still interested in explanation of values for "units.1.properties.0.name" and "units.1.properties.0.value" since can't manage to see them in UI, but this is minor. Thanks.
