| [p2-dev] How to debug: Computing alternate solutions fails to find upgrade solution |
Hi p2 developers, a colleague and I have observed some very weird behavior when installing Ctrlflow Insights [1] into a fresh Eclipse Neon.3 for Java developers (installed by unzipping the ZIP from [2], *not* provisioned by Oomph). We both get the following error message during installation (after a short "computing alternate solutions" wait), but in my case I get a working solution proposed (upgrade three Code Recommenders features to 2.4.7) whereas my colleague is simply told that Ctrlflow Insights cannot be installed. Period. > Cannot complete the install because of a conflicting dependency. > Software being installed: Ctrlflow Insights Single‐User Edition 1.22.1.v20170505-0947-b917 (com.codetrails.ctrlflow.editions.pro.feature.feature.group 1.22.1.v20170505-0947-b917) > Software currently installed: Code Recommenders for Java Developers 2.4.6.v20170307-1041 (org.eclipse.recommenders.rcp.feature.feature.group 2.4.6.v20170307-1041) > Only one of the following can be installed at once: > Code Recommenders Injection Runtime 2.4.0.v20160607-1609 (org.eclipse.recommenders.injection 2.4.0.v20160607-1609) > Code Recommenders Injection Runtime 2.4.3.v20160913-0645 (org.eclipse.recommenders.injection 2.4.3.v20160913-0645) > Code Recommenders Injection Runtime 2.4.5.v20161130-1427 (org.eclipse.recommenders.injection 2.4.5.v20161130-1427) > Code Recommenders Injection Runtime 2.4.6.v20170307-1041 (org.eclipse.recommenders.injection 2.4.6.v20170307-1041) > Code Recommenders Injection Runtime 2.4.7.v20170404-0943 (org.eclipse.recommenders.injection 2.4.7.v20170404-0943) > Cannot satisfy dependency: > From: Ctrlflow Insights Single‐User Edition 1.22.1.v20170505-0947-b917 (com.codetrails.ctrlflow.editions.pro.feature.feature.group 1.22.1.v20170505-0947-b917) > To: com.codetrails.ctrlflow.editions.starter.feature.feature.group [2.5.1,2.6.0) > Cannot satisfy dependency: > From: Ctrlflow Code Search Professional 2.5.1.v20170505-0947-b917 (com.codetrails.ctrlflow.editions.starter.feature.feature.group 2.5.1.v20170505-0947-b917) > To: org.eclipse.recommenders.injection [2.4.7,3.0.0) > Cannot satisfy dependency: > From: Code Recommenders for Java Developers 2.4.6.v20170307-1041 (org.eclipse.recommenders.rcp.feature.feature.group 2.4.6.v20170307-1041) > To: org.eclipse.recommenders.injection [2.4.6.v20170307-1041] We are both running a fresh Eclipse install with a fresh workspace. We even deleted our ~/.eclipse and ~/.p2 folders to ensure that nothing therein was causing this difference in behavior. Any advice on how to debug this?
