Missing requirement resolving feature

Open castortech opened this issue 2 years ago • 1 comments

I am getting the following trying to build a custom version of org.eclipse.emf.cdo

Software being installed: org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier Missing requirement: org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier requires 'org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.dawn.feature.group 0.0.0' but it could not be found

Which also has the long message: [DEBUG] No solution found because the problem is unsatisfiable.: [Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.dawn.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.examples.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.tests.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.server.mongodb.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.server.lissome.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.db.derby.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.db.hsqldb.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.db.mysql.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.db.oracle.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.db.postgresql.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.examples.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.sdk.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.net4j.tests.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.all.feature.group 4.22.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.tests.objectivity 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.sdk.feature.group 5.14.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.server.embedded.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.sdk.feature.group 5.14.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.migrator.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.sdk.feature.group 5.14.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.doc.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.sdk.feature.group 5.14.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.examples.installer.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.sdk.feature.group 5.14.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.server.db.feature.group 0.0.0.; Unable to satisfy dependency from org.eclipse.emf.cdo.sdk.feature.group 5.14.0.qualifier to org.eclipse.equinox.p2.iu; org.eclipse.emf.cdo.compare.feature.group 0.0.0.; No solution found because the problem is unsatisfiable.]

I am running the build in debug mode and also added tycho.debug.resolver=true. I can see that the listed dependencies are found as shown in the list of "Available IUs".

Is there anything wrong with the way the feature is resolved, as it includes other features. The feature contains (untagged to avoid showing blank): ` feature id="org.eclipse.emf.cdo.all" version="4.22.0.qualifier" license-feature="org.eclipse.emf.cdo.license" license-feature-version="0.0.0"

where the included features are both includedUIs and required.

Is that all good and I should look elsewhere or is there something suspicious here?

Is this still a problem for you? If yes please consider providing a reproducer so there is a chance for the problem to be looked at.
