Uses constraint violation - org.slf4j.api vs. slf4j.api ------------------------------------------------------- Key: JBDS-4136 URL: https://issues.jboss.org/browse/JBDS-4136 Project: Red Hat JBoss Developer Studio (devstudio) Issue Type: Bug Components: build, rpm, target-platform Affects Versions: 10.2.0.AM2 Reporter: Nick Boldt Assignee: Nick Boldt Fix For: 10.2.0.AM3 Latest bit of rpm madness...

I removed it from the RPM in favour of the other bundle, which was already installed into the fedora/rhel eclipse. BUT... since this RH SCL rh-java-common *slf4j-api.jar* exports a different, incompatible bundle name: {code}Bundle-SymbolicName: slf4j.api{code} than the one in devstudio's update site / target platform {code}Bundle-SymbolicName: org.slf4j.api{code} NOW, I'm getting this: {code} org.osgi.framework.BundleException: Could not resolve module: org.eclipse.m2e.wtp.jpa [931] Unresolved requirement: Require-Bundle: org.slf4j.api; bundle-version="1.6.2" {code} Snjezana got this too in m2e.core: {code}BundleException: Could not resolve module: org.eclipse.m2e.core.ui [866] Unresolved requirement: Require-Bundle: org.eclipse.m2e.maven.runtime; bundle-version="[1.7.0,1.8.0)" -> Bundle-SymbolicName: org.eclipse.m2e.maven.runtime; bundle-version="1.7.0.20160603-1931"; singleton:="false" org.eclipse.m2e.maven.runtime [876] Unresolved requirement: Require-Bundle: org.slf4j.api; bundle-version="1.6.2"{code} So... not sure what to do to solve this. :( I suppose the best case would be for the m2e and w2e-wtp bundles to depend on the slf4j.api PACKAGES instead of BUNDLES, so that they can run on the fedora/rhel versions instead of those from the devstudio update site / target platform.
