运行 Maven 命令 jenkins 时权限被拒绝

Question

我在 jenkins 的 /home/tes/pom.xml 中的 pom.xml 上运行 maven

clean test

时遇到权限被拒绝的问题。有什么建议

Answer 1

只需授予所有人对 pom.xml 文件的读取权限：

chmod +r /home/tes/pom.xml

Answer 2

就我而言，原因是我没有JDK，而只是在全局工具配置> JDK > JDK安装的JAVA_HOME中配置了JRE。事实上，Jenkins 警告您该路径未指向包含 JDK 的内容。

JDK 是某些插件所必需的，例如 Maven Integration 或 Docker Pipeline，如 Jenkins 文档中的 Java 要求 部分所述。所以必须检查这一点，因为它会令人惊讶地导致奇怪的错误：

正如所提出的解决方案的不同性质所指出的那样，与本案例类似。我想提醒大家注意，这些错误与权限有关，或者解析 pom 可能隐藏了真正的根本原因，并且错误消息并不总是像应有的那样明确和清晰。

Answer 3

我为 jenkins 安装了 Maven 插件，并在根 pom.xml 中提供了 pom.xml 的完全限定路径，它解决了问题

Answer 4

我认为发生这种情况的原因是maven有权运行pom.xml，即。 mvn 命令可以通过终端运行，但不能通过 jenkins 运行。 因此，我们需要将当前用户添加到 jenkins 才能正常工作。
