Git Connector on ModeShape 4.0

[mashama]

I am trying to federate a Git repository with the Git Connector capability provided by ModeShape 4.0.Final running on Wildfly 8.1.Final.  I am able to setup a ModeShape repository with the documentation provided here and finally add the Git external source with the following CLI command:

/subsystem=modeshape/repository=sample/source=git:add(classname="org.modeshape.connector.git.GitConnector",properties=[{"directoryPath"=>"C:\\CHP\\git\\chart_services"}], projections=["default:/projection1 => /git/test"])

However when I attempt to access the federated content via the Modeshape Rest service @ http://localhost:8180/modeshape-rest/sample I don't see anything that resembles the federated content.  I don't see any errors in the log.  What am I missing here?  What am I doing wrong?

You cannot reference the target projection in the Git repository as /git/test. If you don't want to reference the root of the Git repository (i.e. "default:/projection1 => /")  you need to reference one of the connector-aware paths (for example "default:/projection1 => /commit/8dcf7dfc91a8d532749a391d14e9cc8bd78868fa")

See Git connector - ModeShape 4 - Project Documentation Editor for the structure exposed/supported by the connector.

Thanks for your help Horia.  The documentation is a little confusing here.  The projections specification in the JSON lead me down this course. 

{     ...     "externalSources" : {         "local-git-repo" : {             "classname" : "org.modeshape.connector.git.GitConnector",             "directoryPath" : "/home/jsmit/git/MyRepo/",             "remoteName" : "upstream,origin",             "includeMimeType" : true,             "projections" : \[ "/git/MyRepo" \]         }     }     ... }

So I can now access the GIT repository through ModeShape's REST Service.  However when accessing a git:tree node I get the following stacktrace:

http://localhost:8180/modeshape-rest/sample/default/items/projection1/tree/44a4967538e2e95c62a469e40cac2da06bf549e8

I have seen exceptions before when exploring JCR repositories via the REST Service.  Should I be concerned about this one?

[hchiorean]

It seems there are several issues with the GitConnector atm. I've opened [MODE-2352] Git Connector exceptions when navigating via the REST service - JBoss Issue Tracker which we'll hopefully handle for 4.1.

Have you seen the above exception for other connectors as well ? If yes, which ones ? Thanks.

[mashama]

This is the only connector we have delved into at the moment.
