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 pluginat hudson.model.UpdateCenter$InstallationJob._run(UpdateCenter.java:1308)at hudson.model.UpdateCenter$DownloadJob.run(UpdateCenter.java:1107)at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source)at java.util.concurrent.FutureTask.run(Unknown Source)at hudson.remoting.AtmostOneThreadExecutor$Worker.run(AtmostOneThreadExecutor.java:104)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.hpiat hudson.model.UpdateCenter\$UpdateCenterConfiguration.download(UpdateCenter.java:797)    at hudson.model.UpdateCenter\$DownloadJob._run(UpdateCenter.java:1148)    at hudson.model.UpdateCenter\$InstallationJob._run(UpdateCenter.java:1309)    at hudson.model.UpdateCenter\$DownloadJob.run(UpdateCenter.java:1126)    at java.util.concurrent.Executors\$RunnableAdapter.call(Executors.java:511)    at java.util.concurrent.FutureTask.run(FutureTask.java:266)    at hudson.remoting.AtmostOneThreadExecutor$Worker.run(AtmostOneThreadExecutor.java:110)    at java.lang.Thread.run(Thread.java:745)

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"
