I have downloaded and installed Apache MCF 1.6.1 source locally. I built it using three commands : ant make-core-deps, ant make-deps & ant build.
Everything went smooth. Then i started MCF & created an output connection to Sols and 3 different repository connections to Alfresco using CMIS, Sharepoint and Shared Drive. I have used my custom code placed into repository connectors to get extra fields for solr index.
Then i created three jobs using above three repository connections. First i started Alfresco job, it works fine.
