Keychain won't unlock from Jenkins script unless user logged in

I had to:

Right-click on the private key in my keychain that my build processwas trying to use
Click "Get Info"
Then the "Access Control" tab.
You can add specific apps (like "codesign") to the list of apps thatare allowed access to that key, or just allow access from all applications.

This cleared it up for me.

Running Jenkins without launchd works. I used the following command:

sudo su jenkins -c "JENKINS_HOME=/Users/Shared/Jenkins/Home /Library/Application\ Support/Jenkins/jenkins-runner.sh"

xcode macos hudson jenkins keychain

I stumbled upon the exact same issue recently.

security list-keychains -s /Users/john/Library/Keychains/xcode.keychain probably will fix your problem. Let me know if it works.
