Github Repository configuration set to NOT clean but it still does.

[lance_lyons]

Hi,  We have a CI environment that is on a network with limited bandwidth.  This is being fixed but will take a little longer.  We set the bamboo build repository settings to not do a clean build to improve the time since 1 of our repos is 3gb big.  With the source code repo set to not clean, we still have times where it does do a full clean as shown below.

How can I prevent this?  Would caching the repo on remote agents help this performance?

Any other suggestions other than the obvious of getting the network bandwidth fixed.

Thanks in advance

Hi Lance,

Can you try disabling Use shallow clone in the respective linked repository? (And clear fit cache under *Overview -> Repository settings*)

It appears like the checkout of a specific revision is failing and I suspect it could be due to the shallow clone with depth=1 because the checkout seem to happen when it is cloned fully subsequently.

You can try cloning outside Bamboo via command line and see if you can reproduce this issue.

That said, enabling repository caching on agent will definitely help. (found under Git Repository's advanced options) This creates a full clone of the repository in agent directory fit the first time. All remote updates go into that repository and because that repository is not destroyed between builds, Bamboo does the checkout from that repository into the build working dir. So, even if you need clean checkout, it should be quite fast.

Hope that helps.
