tigger specific branch is worked but checkout is not the specific branch

[csrlsm]

I configured gwt with jenkins+github，and it works. but when the job was tiggered, git checkout to the main branch. for example, i push to the "origin/test" bransh and tigger by webhook, but git fetch all branch and checkout to the main branch.

the output messages from job as follow:

... Contributing variables:

ref = refs/heads/test
