如何在Maven管道中使用Maven插件

编程问答 2022-08-12

问题描述

我在withMaven上使用詹金斯（Jenkins）腰线：

我尝试：

stage('Download binary') {
    steps {
        script {
            def Constants = com.comp.Constants
            withMaven(globalMavenSettingsConfig: 'empty-global-settings',mavenSettingsConfig: Constants.CONfig_SETTINGS_ID) {                  
                // download jar file
                sh "$MVN_CMD org.apache.maven.plugins:maven-dependency-plugin:get --define artifact=${artifact} --define transitive=false"
                sh "$MVN_CMD org.apache.maven.plugins:maven-dependency-plugin:copy --define artifact=${artifact} --define mdep.stripVersion=true --define outputDirectory=${WORKSPACE}"
            }
        }
    }
}

但是我有这个错误：

$ docker exec 023505fd08232c4b1e385684169e15195a16d6af31928308374582e757e0e520 env printenv MAVEN_HOME
$ docker exec 023505fd08232c4b1e385684169e15195a16d6af31928308374582e757e0e520 env printenv M2_HOME
$ docker exec 023505fd08232c4b1e385684169e15195a16d6af31928308374582e757e0e520 env /bin/sh -c "which mvn"
[withMaven] Maven installation not specified in the 'withMaven()' step and not found on the build agent
...
hudson.remoting.ProxyException: groovy.lang.MissingPropertyException: No such property: MVN_CMD for class: WorkflowScript

我尝试这样做并解决了我的问题（这很奇怪而且很丑）：

stage('stub for workaroud') {
    steps {
        script {
            def Constants = com.comp.Constants
            checkoutGitSCM(
                    url: "${Constants.BITBUCKET_URL}/stub.git",tag: Constants.STUB_TAG
                 )
            }
        }
    }
}

很奇怪，如果我添加了一个checkoutGitSCM，$MVN_CMD的步骤，并且有[withMaven] using Maven installation provided by the build agent with the environment variable MAVEN_HOME=/usr/local/share/maven

编辑：

我添加了sh "env"命令。在我拥有checkoutGitSCM之前，

MVN_CMD=/home/jenkins/workspace/MyJob@tmp/withMaven10a4d8db/mvn
MVN_CMD_DIR=/home/jenkins/workspace/ODM_Common_XLD_deploy@tmp/withMaven10a4d8db

如果我使用sh "$MVN_CMD_DIR/mvn org.apache.maven.plugins:maven-dependency-plugin:get...不再起作用，则需要在checkoutGitSCM之前使用withMaven

我将FINE的日志级别添加到org.jenkinsci.plugins.pipeline.maven.WithMavenStepExecution2，结果是：

Sep 04,2020 3:29:45 PM FINE org.jenkinsci.plugins.pipeline.maven.WithMavenStepExecution2 obtainMavenExec
