After setting up the Eclipse IDE with all the 3.x branches I waited until the initial setup tasks has been done. I also triggered the menu to performe the setup task after that.
But especially all the openhab-core bundles complained about a missing classpath directory “target/dependency” (the EEA classpath).
If my understanding has been correct the maven-dependency-plugin is responsible to download the EEAs to that directory.
Is it (still) necessary to build openhab-core using mvn on the console to get all IDE errors resolved?
I assume this error in the IDE is related:
Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-dependency-plugin:3.1.1:unpack (execution: unpack-eea, phase: process-sources)
