研究方向: The issue describes a bug where manual plugin installation in Jenkins 2 does not handle detached plugins, causing an installation error when deploying the Ownership plugin which depends on code decoupled to the Matrix Auth plugin. To reproduce, look at the plugin installation mechanism in the Jenkins core, specifically the PluginManager class and its handling of dependencies. The maintainer should investigate how detached plugins are resolved during manual upload vs. automatic installation. The report mentions ownership 0.5 and Jenkins 2.16; the test environment and error screenshot are attached. Start by examining the code path for manual plugin installation, particularly the update center logic and how missing dependencies are handled. No linked PRs or assignees, so the issue is open for contribution.
