angular-ui-tree library is packaged twice in the dashboard.war

Running mvn verify on the dashboard module produces the dashboard.war.
Inspection of the war contents show that angular-ui-tree is packaged twice:

components/angular-ui-tree/dist/angular-ui-tree.min.js
js/lib/angular-ui-tree.js

Seems to me that one of them is redundant and needs to be deleted.
