I worked it out! The system log of Jenkins showed me the hints. The problematic git client plugin and parameter plugin were not loaded due to missing dependencies plugins, such as git plugin and build step plugin. Reinstalling the missing plugins fixed the problem.
It's really strange why the git plugin and so on became uninstalled. I recall some plugins failed to be upgraded due to network issue. Anyway the partial upgrading of plugins should not break the plugin loading.
