Getting error 'FATAL: Failed to recompute children' when trying to build indexes on a multi branch pipeline.

[isha chishty]

HI, 

I am new to Jenkins and getting error when trying to build a pipeline using GIT.

first it says no jenkinsfile but surprisingly there is a jenkins file in root folder. 

On trying to build indexes manually it gives me following error.

================================================================================================================

Can somebody help on this.

The default timeout for git operations in the Jenkins git plugin is 10 minutes.  You're reaching that timeout.

Some possible reasons for that timeout:

• Authentication is blocked in command line git, waiting for a username and/or password to be entered.  Be sure that you've assigned credentials to the job and are using those credentials
• Repository is so large that it needs more than 10 minutes to clone.  Increase the timeout from the "Advanced clone options", or reduce the clone time by creating a reference repository on the agent, and include the path to that reference repository in the "Advanced clone options" of the job definition
• Bandwidth to git repository is limited enough that it needs more than 10 minutes to clone.  Apply same techniques as "large repository" above
