Warning Messages

[[WARNING] Mirror tool: "Problems resolving provisioning plan."...

This message may be shown by the tycho-p2-repository-plugin (in version 0.13 or later) when an eclipse-repository module includes a feature patch. Feature patches allow to replace plug-ins contained in a feature with different versions of the plug-ins, so a target platform containing a feature and a corresponding feature patch has only the new versions of the plug-ins. The p2 mirror tool, which is used by the tycho-p2-repository-plugin, mirrors from the resolved target platform, but it is not aware of the semantics of feature patches. Therefore it also tries to mirror the original versions of the plug-ins, and issues a warning when it fails to do so.

In case the warning only reports unsatisfied dependencies to the original versions of plug-ins replaced through a feature patch, it can be safely ignored. All other cases probably indicate an internal error in Tycho and should be reported.
