[ https://issues.jboss.org/browse/JBDS-4183?page=com.atlassian.jira.plugin.... ] Nick Boldt commented on JBDS-4183: ---------------------------------- So... with some tweaks to the specfile for the devstudio RPM, I now have a number of working symlinks, which prevent constraint violations for slf4j and httpcomponents.httpclient. Steps to verify: {quote} 1. install from latest rpm 2. Help > Install New > https://devstudio.redhat.com/10.0/snapshots/updates/ *{color:red}NOT from STABLE or Central {color}* 3. uncheck "group items by category" 4. select cordovasim feature (v20161115 or newer) 5. restart when prompted 6. ll ~/.eclipse/org.eclipse.platform_*_linux_gtk_x86_64/plugins Should not see anything from java.servlet(.api), org.apache.httpcomponents.httpclient(.cache) But will likely see org.slf4j.api 1.7.2, which is probably OK as it's needed by other *slf4j* jars in the devstudio rpm install 7. install the rpm feature to update everything in devstudio to latest snapshot version from https://devstudio.redhat.com/10.0/snapshots/updates/ 8. install all categorized features from https://devstudio.redhat.com/10.0/snapshots/updates/ Result: {code}#➔ ls .eclipse/org.eclipse.platform_*_linux_gtk_x86_64/{plugins,features} | egrep -v "org.jboss.tools|org.eclipse.thym|org.jboss.ide|hibernate|com.jboss.devstudio" .eclipse/org.eclipse.platform_283378046_linux_gtk_x86_64/features: org.eclipse.linuxtools.vagrant.feature_2.1.0.201609141916 .eclipse/org.eclipse.platform_283378046_linux_gtk_x86_64/plugins: org.apache.commons.lang_2.6.0.v201404270220.jar org.apache.xml.resolver_1.2.0.v201005080400.jar org.apache.xml.serializer_2.7.1.v201005080400.jar org.eclipse.jetty.rewrite_9.3.9.v20160517.jar org.eclipse.linuxtools.vagrant.core_2.0.0.201609141916.jar org.eclipse.linuxtools.vagrant.docs_2.0.0.201609141916.jar org.eclipse.linuxtools.vagrant.ui_2.0.0.201609141916.jar org.slf4j.api_1.7.2.v20121108-1250.jar{code} 9. install *everything* from central (using the snapshots site in the background - you can verify this by looking for m2e feature - org.eclipse.m2e.feature.feature.group - 1.7.1.20161104-1805, not something older). 10. On restart, Eclipse {color:red}*crashed*{color}... but when I restarted in a fresh workspace, it opened fine, despite some {color:orange}*NPE from ZeroTurnaround*{color} and the *{color:green}expected{color}* "Another singleton bundle selected" warnings caused by Eclipse's inability to remove old singletons from the /opt/rh folder which are also now installed in ~/eclipse/.{quote} -- This message was sent by Atlassian JIRA (v7.2.3#72005)
