'gradle eclipse' or 'gradle idea' continue executing even if some dependencies are unresolved. This is expected behavior because the user might be interested in working in IDE even though some dependencies are unresolved. However, it would be nice to warn the user ahead that something is wrong, rather than wait until he cannot build the project in the IDE. The problem is not critical because the unresolved dependencies in IDE have an extra 'unresolved' label that helps understanding why the project does not build. Nevertheless we should consider printing a warning if some dependency is unresolved at build time.
