I am trying to build existing websocket plugin myself. So i cloned openfire(GitHub - igniterealtime/Openfire: A XMPP server licensed under the Open Source Apache License. ), then went to /src/plugins/websocket. (using ubuntu 16.04 OS). Then executed ‘mvn clean install’. Here is the error i got:
[ERROR] Failed to execute goal on project websocket: Could not resolve dependencies for project org.igniterealtime.openfire.plugins:websocket:jar:1.2.0: The following artifacts could not be resolved: org.apache.mina:mina-core:bundle:2.0.7, org.apache.mina:mina-integration-beans:bundle:2.0.7, org.apache.mina:mina-integration-ognl:bundle:2.0.7: Failure to find org.apache.mina:mina-core:bundle:2.0.7 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
