Unsatisfied dependency on startup

[Steve Michaels]

Now that I've got the database migrated, startup is giving me an unsatisfied dependency error:

Hello,

ran into the same problem, fixed by runnning

mvn clean install 

before mvn package (maybe not necessary after all). also make sure you're running same java version in mvn, ant and tomcat.

greetings.

[Steve Michaels]

Ran mvn clean install before mvn package and then the ant fresh_install process.

I'm still getting a null pointer exception.

Hi,

Someone else recently ran into this odd error in our Slack.  We've tracked it down to being a Solr connection issue.  See this bug ticket which describes the entire problem: https://github.com/DSpace/DSpace/issues/9217

Basically, there should be a logged ERROR *before* this NullPointerException which is the *real error*.  It will likely say that your DSpace backend isn't able to connect to Solr.

I have been able to find some configuration issues and an ownership issue with a few sequences, but still no joy on starting the backend.

I'm still getting a SEVERE Null PointerException.

[Steve Michaels]

OK, I got the back end up.  On to the front end with its own issues.
