jenkins安裝git插件遇到的問題

1、安裝了jenkins（但是安裝后不知道怎么查看安裝的是jenkins的版本）

2、通過系統設置->插件管理中->可選插件或高級，我的可選插件中沒有信息，所以我通過高級中的上傳插件的方式安裝插件的

3、安裝git.hpi插件前，需要安裝git_client.hpi插件、scm-api.hpi插件、workflow-setp-api.hpi插件、workflow-scm-setp.hpi插件，否則安裝git.hpi時會報錯，錯誤提示如下：

請按順序安裝負責安裝(可根據錯誤提示調整安裝順序)插件是可能提示依賴的插件未安裝，如先安裝了workflow-scm-step.hpi時未安裝workflow-setp-api.hpi則會提示錯誤

注釋：插件的版本號需要根據git插件依賴中提到的版本號安裝，

scm-api (1.0), workflow-scm-step (1.14.2), git-client (1.19.6) 
workflow-setp-api.hpi（1.14.2）（貌似與workflow-scm-step保持一致）

4、前面的插件安裝完成后，下載git插件git.hpi(https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin)

安裝version：2.5.3的git.hpi報錯（如下），在網上查了一下，有人在部署war文件是類似錯誤說是因為java的版本問題，編譯時用的java jdk的版本與發布的服務器上

java jdk版本不一致導致的,也可能是下載的2.5.3有問題吧，具體原因不明，但是經測試，換成2.5.2就不會出現此問題，2.5.1，2.5.0仍然會出現此問題

總結：安裝git插件時，在官網下載git的頁面中有對其他依賴插件的提示,如下圖所示：
