When using the Eclipse Jetty plugin (http://marketplace.eclipse.org/content/eclipse-jetty?mpc=true&mpc_state=), I started to get the following error:
An internal error occurred during: "Launching myProject".
Unknown scope: test,provided
This started to occur for two separate projects, both on Windows and MacOs X systems. Note that a regular Jetty deployment, as well as the Jetty runner Maven plugin, work like a charm, the problem seems to be with the Eclipse plugin only. The problem persists after upgrading the plugin to the newest version. Changing Jetty versions doesn't help as well.
edit: Thanks for the tips so far. The question is what might be the source of this problem and how to get rid of it. The relevant log message is as follows:
!ENTRY org.eclipse.core.jobs 4 2 2016-04-27 09:01:40.914
