詹金斯找不到maven可执行文件

Question

我正在尝试在 Jenkins 上配置一个简单的 maven 构建，但是当我运行构建时 jenkins 找不到我的 maven 可执行文件。

这是我的 Jenkins 文件：

node {
    def rtMaven = Artifactory.newMavenBuild()

    stage 'Clone sources'
    git url: 'https://github.com/user/project.git'

    stage 'Artifactory configuration'
    rtMaven.tool = "Maven-3.5.0"

    stage 'Maven build'
    def buildInfo = rtMaven.run pom: 'project/pom.xml', goals: 'clean install'
    }

我收到的错误是这样的：

Entering stage Maven build

Jenkins Artifactory Plugin version: 2.11.0
ERROR: Couldn't find Maven executable.

我错过了什么吗？ 也许是一个插件。

您甚至可以查看您的JENKINS_HOME 目录下的hudson.tasks.Maven.xml 文件。 示例输出：

名称将在hudson.tasks.Maven_-MavenInstallation>name下

此错误看起来像是您在管道脚本中指定了错误的名称。您应该使用 maven 工具配置中的那个。
