试试下面几个命令选择 java 8

Jenkins 的用户和你不是同一个，所以你们的环境也不一样，所以他用 Java7，你用 Java8

kaneg 2018-05-12 22:48:44 +08:00 via iPhone
因为系统环境的千差万别，这种 Java 多版本引起的问题很常见，所以用 docker 这种专门解决环境差异的方案是终极解决之道

zhantss 2018-05-12 22:52:34 +08:00
安装版的 jenkins，默认是创建了一个 jenkins 用户，改这个用户的配置就行
防止发生意外可以改 /etc/default/jenkins 里面的设置，不一定是这个位置，你可以查一下对应软件包的配置文件位置 |

Docker Jenkins 更方便，哈哈

zqcolor 2018-05-13 13:03:30 +08:00
那就卸载这个 openjdk7
/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 然后安装 jdk 8 试试 |

wsds OP @zhantss 有这个文件，要改什么内容啊

网上查的，可以试试看
https://stackoverflow.com/questions/49367311/start-jenkins-with-jdk-8-without-changing-system-java-home Set JENKINS_JAVA option in /etc/sysconfig/jenkins file. The variable name might be different depending on your operating system and package source but the /etc/sysconfig/jenkins file is usually the configuration file for your jenkins service. |

wsds OP 还是不行啊

两年了。。。
我自己这样暴力设置可以起来 1. cd /etc/init.d 2. sudo vim jenkins 3. 注释掉 PATH 部分，因为之前编译多个版本的 AOSP，java 环境乱的压批，在 /etc/profile 里 export 了，在这里直接加上 source /etc/profile ubuntu@linux:/etc/init.d$ ./jenkins -> Correct java version found 最后，docker 大法好 |

TreePu 2020-12-04 16:41:09 +08:00
1，安装 JDK1.8：sudo apt-get install openjdk-8-jdk
2，切换 JDK 版本：sudo update-alternatives --config java 输入数字，Enter 3，修改 Jenkins 配置文件的 PATH 为 1.8 的路径 sudo vi /etc/init.d/jenkins ## PATH=/bin:/usr/bin:/sbin:/usr/sbin 旧的 PATH=/usr/lib/jvm/java-8-openjdk-amd64/bin/java 新的 4，重启 Jenkins，成功 今天遇到了，把解决过程分享一下 |
