jenkins安装git插件遇到的问题

1、安装了jenkins（但是安装后不知道怎么查看安装的是jenkins的版本）

2、通过系统设置->插件管理中->可选插件或高级，我的可选插件中没有信息，所以我通过高级中的上传插件的方式安装插件的

3、安装git.hpi插件前，需要安装git_client.hpi插件、scm-api.hpi插件、workflow-setp-api.hpi插件、workflow-scm-setp.hpi插件，否则安装git.hpi时会报错，错误提示如下：

请按顺序安装负责安装(可根据错误提示调整安装顺序)插件是可能提示依赖的插件未安装，如先安装了workflow-scm-step.hpi时未安装workflow-setp-api.hpi则会提示错误

注释：插件的版本号需要根据git插件依赖中提到的版本号安装，

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

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

安装version：2.5.3的git.hpi报错（如下），在网上查了一下，有人在部署war文件是类似错误说是因为java的版本问题，编译时用的java jdk的版本与发布的服务器上

java jdk版本不一致导致的，具体原因不明，但是经测试，换成2.5.2就不会出现此问题，2.5.1，2.5.0仍然会出现此问题
