Re: [tycho-user] Unresolved dependency after migration from Tycho 12.0 to 14.1

Step 1 is the computation of the target platform, which may include resolving target files and loading the p2 repositories configured in the POM. In case of p2 repos in the POM, there may be a very large number of artifacts in the target platform.

Therefore there is a step "1.5", which is the p2 resolution of the project dependencies (and this step is always done, and this is intentional). This leads to a reasonably small list of artifacts. These "dependency artifacts" are downloaded and fed into step "2", the Equinox OSGi resolver (for computing the compile class path).

If p2 was perfect, step 2 would never fail. But due to bugs like [1] you may see problems like the one you have.

Tobias
