I configured JBoss Tools -> Remote Repositories and tried to install the addon org.jboss.fuse.forge.addon:fuse-forge,1.0.0.redhat-000013
which requires one of these repositories http://repository.jboss.org/nexus/content/groups/ea or https://intranet.acme.com/nexus/content/repositories/jboss-eap-6.x-maven-repository
I need to modify my settings.xml to include the repository to have it working
