When I create Multibranch Pipeline and add a git source (which requires a private key to authenticate) branch indexing doesn't work and throws following exception:
java.lang.IllegalStateException: Cannot open session, connection is not authenticated. at com.trilead.ssh2.Connection.openSession(Connection.java:1127) at org.jenkinsci.plugins.gitclient.trilead.TrileadSession.exec(TrileadSession.java:32) at org.eclipse.jgit.transport.TransportGitSsh$SshFetchConnection.<init>(TransportGitSsh.java:262) at org.eclipse.jgit.transport.TransportGitSsh.openFetch(TransportGitSsh.java:161) at org.eclipse.jgit.transport.FetchProcess.executeImp(FetchProcess.java:136) at org.eclipse.jgit.transport.FetchProcess.execute(FetchProcess.java:122) at org.eclipse.jgit.transport.Transport.fetch(Transport.java:1138) at org.eclipse.jgit.api.FetchCommand.call(FetchCommand.java:130) at org.jenkinsci.plugins.gitclient.JGitAPIImpl.fetch(JGitAPIImpl.java:672) at jenkins.plugins.git.AbstractGitSCMSource.retrieve(AbstractGitSCMSource.java:171) at jenkins.scm.api.SCMSource.fetch(SCMSource.java:146) at jenkins.branch.MultiBranchProject.computeChildren(MultiBranchProject.java:296) at com.cloudbees.hudson.plugins.folder.computed.ComputedFolder.updateChildren(ComputedFolder.java:151) at com.cloudbees.hudson.plugins.folder.computed.FolderComputation.run(FolderComputation.java:110) at hudson.model.ResourceController.execute(ResourceController.java:98) at hudson.model.Executor.run(Executor.java:410)
It looks like jgit is used by default, but I don't have it in "Manage Jenkins" I have only command line git, which should be used.

[JENKINS-33983] Multibranch Pipeline with git uses jgit, but should use git installation that is configured
That said, I do not know why you encountered this error. Both CLI Git and JGit support SSH private key authentication. Did you specify your private key under Credentials in the SCM source configuration?
dc00, the problems seems to be that JGit is used, so configuring Jenkins explicitly to use JGit will likely not fix that. I am running into the same problem as the requester has, JGit is used despite I have only one git configuration and that is a local one (that works from console).

added a comment - I have same this problem. I had same issue.
Seems that it is related somehow how you defined git credentials in jenkins.
No problem if you copied PK directly to credential.
No problem if you give full path of private key: /usr/lib/jenkins/.ssh/id_rsa for example
Problem occured when using relative path ~/.ssh/id_rsa
Hope this helps someone

Hope this helps someone jglick I have a dependency on CLI git as we use an SSH over HTTP tunneling config. I don't think JGit is able to support this..
EDIT: There is an open ticket on support extra SSH options in JGit also - JENKINS-28351

So to further elaborate on this, a workaround is to go into "Manage Jenkins" -> "Global Tool Configuration" then under "Git" click "Add Git" then select "JGit". See also https://wiki.jenkins-ci.org/display/JENKINS/Git+plugin+2.0+beta+testing#Gitplugin2.0betatesting-ActivatingJGit.
The attached links says "go to the system configuration page" which should read "go into the Global Tool Configuration page".
