You can't change the Jenkins git client plugin from using ASKPASS to using .gitcredentials. The plugin does not have selectable password prompting methods.
It used .gitcredentials in releases prior to 2.0, and switched to ASKPASS in releases 2.0 and later. That change was made so that submodule authentication could be added in git client plugin 2.0. There are open bug reports which describe scenarios where Windows based username / password setups no longer work with https based access to a git repository. Some of those scenarios include: - Password contains a character which requires Windows escaping, but the plugin does not escape the password correctly (JENKINS-40166 <https://issues.jenkins-ci.org/browse/JENKINS-40166>, JENKINS-38194 <https://issues.jenkins-ci.org/browse/JENKINS-38194>, and JENKINS-38179 <https://issues.jenkins-ci.org/browse/JENKINS-38179>) - Unknown failure mode with TFS 2105 (JENKINS-38138 <https://issues.jenkins-ci.org/browse/JENKINS-38138>) Some temporary alternatives prior to the fixes for those open bugs include: - Stay with your current versions (git client plugin 1.19.6 and git plugin 2.x) - upgrade Jenkins but don't upgrade the git client plugin and the git plugin - Manually upgrade to the latest git client plugin 1.x and latest git plugin 2.x by downloading and installing git client plugin 1.21.0 <https://updates.jenkins-ci.org/download/plugins/git-client/1.21.0/git-client.hpi> and git plugin 2.6.1 <https://updates.jenkins-ci.org/download/plugins/git/2.6.1/git.hpi> so that you can stay with git client plugin prior to the credentials change. You'd need to download those files, then use the Jenkins plugin manager "Advanced" tab to upload those newer (but not newest) versions of the git client plugin and git plugin - Upgrade to latest git client and git plugin, and change your Git URL's from using username / password (https) authentication to using private key (ssh / scp) credentials, store those private keys as Jenkins credentials, and update the jobs to use those private key credentials rather than username / password credentials - Change your git account passwords to not use characters which require escaping through the Windows command prompt - Assist with evaluation of the pending git client plugin pull request which adjusts the Windows escaping of passwords in the plugin. The pull request is PR231 <https://github.com/jenkinsci/git-client-plugin/pull/231> on github My apologies for those bugs. The year of beta testing before release of git client plugin 2.0 was not enough to detect those problems.
