Jenkins安装gitlab hook plugin失败的解决办法

jenkins在安装git hook plugins提示失败:

OS : CentOS 6.5 64位
Jenkins : 1.638
JDK : 1.8.0_66
Ruby-runtime : 0.12
问题 : gitlab hook plugin无法安装的原因是因为ruby-runtime无法安装.

java.io.IOException: Failed to dynamically deploy this plugin

at java.lang.Thread.run(Unknown Source)

解决办法:

1. 看上去是在下载过程中文件出现了问题. 首先关闭Jenkins.找到jenkins主目录下面的插件目录,我的目录在/home/web/.jenkins/plugins, 删除相关文件gitlab-hook.jpi和ruby-runtime.jpi

2. 重启jenkins, 试着重新安装.还是无法安装成功,报错信息,应该是下载文件的网络问题:

hudson.util.IOException2: Failed to download from http://updates.jenkins-ci.org/download/plugins/ruby-runtime/0.12/ruby-runtime.hpi

手动下载相关的文件,现在地址在这里, 找到相关的插件,然后选择版本.下载到本地

进入jenkins的系统设置->插件管理->高级->上传插件,把下载到本地文件的插件上传到jenkins的服务器进行安装.

还是报错:

网上继续寻找问题,在Jenkins的官网找到一个issue, 描述的就是这个问题. Phellipe Ribeiro最后给出了一个在CentOS的临时解决方案:

编辑Jenkins的配置文件 /etc/sysconfig/jenkins 的JENKINS_JAVA_OPTIONS

修改后 :

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Dhudson.ClassicPluginStrategy.noBytecodeTransformer=true"
