Question

我一直在使用Jenkins和Maven来运行我的一些自动化作业，但最近我发现控制台日志在干净安装过程中一直显示相同的错误。我尝试在线更新JAVA_HOME和其他各种各样的东西，但没有一个工作。即使作业完成并通过构建也只是失败导致错误：

Answer 1

看起来像詹金斯无法选择jdk。请检查您的JAVA_HOME是否已设置并指向JDK。

您还可以尝试从jenkins UI设置JAVA_HOME，如下所示：

Go To Jenkins -> Manage Jenkins -> Configure System -> JDK. Configure path to the JDK under JAVA_HOME field.

Answer 2

至少有两个其他来源表明，对于远程代理，您需要在节点配置中为指向java.home的环境变量指向JAVA_HOME目录（不仅仅是{{1 }}或类似的内容。

导航至%JAVA_HOME%，然后单击远程节点旁边的配置图标。在此处，向下滚动至“节点属性”，在Jenkins > Manage Jenkins > Manage Nodes的复选框中打勾，并为名称定义Environment Variables，并为值定义JDK的路径，例如java.home

这是我最终要做的，即使在构建代理服务器上发现所有系统环境变量都正确并且c:\Program Files\Java\jdk1.8.0_181和java -version都在正确报告之后。

我意识到OP没有指定“主控”或“远程”，但是希望这对偶然发现此问与答的人有所帮助。

此消息提供了第一个线索，但没有解释：https://www.pgs-soft.com/blog/oops-jenkins-slave-maven-not-working/

我无法追踪我在谷歌搜索时发现的关于此修复程序的其他提及。

Jenkins Maven项目在此环境中未提供编译器
