Failed install fails to inform user, or to recover with other deps

[supertick]

Describe the bug
If the ivy dep loader on install fails, the next restart will not report the information to the user

To Reproduce
Steps to reproduce the behavior:

1. Have a failed dependency resource, either because repo is not available, or resolve conflict
   e.g. " Multiple artifacts of the module org.apache.opennlp#opennlp-tools;1.6.0 are retrieved to the same file! Update the retrieve pattern to fix this error."

2. wait for UI to come up - no indication of error until inadvertently run into consequences of missing dependency

Expected behavior
Preferably, continue to resolve "other" dependencies that are available.
Minimally, clear error information on the UI startup that an install error occurred, and some possible remedies "remove .ivy2 cache and try restarting"
