Hi
I faced with issue with ‘com.genericworkflownodes.knime’ plugin for KNIME 3.3.4 after new version rolling out (‘0.8.100.v201806231040’ instead of ‘0.8.100.v201805141406’). I mirrored this version of plugin from http://update.knime.org/community-contributions/trusted/3.3 on July 12
Mirroring artifacts for http://update.knime.org/community-contributions/trusted/3.3
Mirroring: org.eclipse.update.feature,com.genericworkflownodes.knime.feature,0.8.100.v201806231040 (Descriptor: canonical: org.eclipse.update.feature,com.genericworkflownodes.knime.feature,0.8.100.v201806231040)
Mirroring: osgi.bundle,com.genericworkflownodes.knime,0.8.100.v201806231040 (Descriptor: canonical: osgi.bundle,com.genericworkflownodes.knime,0.8.100.v201806231040)
and since this time I have troubles with mine regression testing
