# Jenkins on Windows 心得分享 (07)：如何手動更新 Jenkins 伺服器所有外掛

當你已經安裝一大堆 [Jenkins Plugins](https://plugins.jenkins.io/)，想要全部自動更新，但是又連不到 Jenkins 指向的 Mirror Sites 的話，想必就只能手動更新了。本篇文章延續 [Jenkins on Windows 心得分享 (06)：如何指定 Mirror 鏡像網站下載外掛](/post/2021/05/02/Jenkins-on-Windows-06-Specify-Mirror-Site-to-Download-Plugins) 的內容，特別補充如何手動更新 Jenkins 伺服器所有外掛(Plugins)。

### 取得目前 Jenkins 所有 Plugins 清單

1.  開啟 Manage Jenkins > Script Console 輸入命令
    
    ![Manage Jenkins > Script Console](https://stwillblogassets.blob.core.windows.net/files/images/external/user-images.githubusercontent.com/8e91c80be012e234cfb7-116950473-ac060380-acb7-11eb-948e-c19733d723f6.png)
    
2.  輸入以下 [Groovy script](http://www.groovy-lang.org/) 命令，並按下 **Run** 按鈕執行
    
    ```javascript
    Jenkins.instance.pluginManager.plugins.each{ plugin -> print ("${plugin.getShortName()} ") } println ("")
    ```
    
    輸出結果會顯示目前 Jenkins 所有安裝過的 Plugins 清單：
    
    ```
    jjwt-api git workflow-aggregator workflow-support git-client jdk-tool command-launcher pipeline-milestone-step msbuild ws-cleanup github okhttp-api mailer credentials plain-credentials github-branch-source pipeline-model-api display-url-api bouncycastle-api pipeline-github-lib momentjs ace-editor pipeline-input-step handlebars jquery3-api pipeline-rest-api pipeline-stage-tags-metadata bootstrap4-api workflow-multibranch cloudbees-folder workflow-cps-global-lib build-timeout antisamy-markup-formatter branch-api ant scm-api workflow-cps junit matrix-project pipeline-build-step pipeline-stage-step pipeline-model-extensions timestamper checks-api ssh-credentials font-awesome-api workflow-step-api git-server echarts-api lockable-resources email-ext matrix-auth apache-httpcomponents-client-4-api workflow-job ssh-slaves pipeline-graph-analysis ldap jsch pipeline-model-definition structs github-api workflow-api trilead-api popper-api credentials-binding gradle workflow-basic-steps snakeyaml-api plugin-util-api locale durable-task jackson2-api workflow-durable-task-step workflow-scm-step pipeline-stage-view resource-disposer token-macro pam-auth script-security
    ```
    
    > 請將執行結果的 Plugins 清單複製到**剪貼簿**。
    

### 批次更新 Plugins 到最新版

1.  設定 Jenkins Mirror Site (詳見 [Jenkins on Windows 心得分享 (06)：如何指定 Mirror 鏡像網站下載外掛](/post/2021/05/02/Jenkins-on-Windows-06-Specify-Mirror-Site-to-Download-Plugins) 文章說明)
    
    ```bash
    export JENKINS_UC_DOWNLOAD=http://ftp.yz.yamagata-u.ac.jp/pub/misc/jenkins/
    ```
    
2.  設定要安裝的 Plugins 清單
    
    ```bash
    export ALL_PLUGINS='jjwt-api git workflow-aggregator workflow-support git-client jdk-tool command-launcher pipeline-milestone-step msbuild ws-cleanup github okhttp-api mailer credentials plain-credentials github-branch-source pipeline-model-api display-url-api bouncycastle-api pipeline-github-lib momentjs ace-editor pipeline-input-step handlebars jquery3-api pipeline-rest-api pipeline-stage-tags-metadata bootstrap4-api workflow-multibranch cloudbees-folder workflow-cps-global-lib build-timeout antisamy-markup-formatter branch-api ant scm-api workflow-cps junit matrix-project pipeline-build-step pipeline-stage-step pipeline-model-extensions timestamper checks-api ssh-credentials font-awesome-api workflow-step-api git-server echarts-api lockable-resources email-ext matrix-auth apache-httpcomponents-client-4-api workflow-job ssh-slaves pipeline-graph-analysis ldap jsch pipeline-model-definition structs github-api workflow-api trilead-api popper-api credentials-binding gradle workflow-basic-steps snakeyaml-api plugin-util-api locale durable-task jackson2-api workflow-durable-task-step workflow-scm-step pipeline-stage-view resource-disposer token-macro pam-auth script-security'
    ```
    
3.  使用 `jenkins-plugin-cli` 安裝 Plugins 外掛
    
    ```bash
    jenkins-plugin-cli --verbose -d $JENKINS_HOME/plugins/ --plugins $ALL_PLUGINS
    ```
    
    如果網路環境一定要透過 Proxy 來安裝 Plugins 的話，請到 [Plugin Installation Manager Tool for Jenkins](https://github.com/jenkinsci/plugin-installation-manager-tool) 下載 `jenkins-plugin-manager-*.jar` 檔案回來，啟動程式時給予 `http.proxyPort` 與 `http.proxyHost` 指令(Directive)即可：
    
    ```bash
    java -Dhttp.proxyPort=3128 -Dhttp.proxyHost=myproxy.example.com -jar ./jenkins-plugin-manager-2.9.2.jar --verbose -d $JENKINS_HOME/plugins --plugins $ALL_PLUGINS
    ```
