jenkins - Jenkins 管道中的 Artifactory : org. codehaus.groovy.runtime.GStringImpl 无法转换为 java.lang.String

Question

我的 Jenkinsfile 中有这个:

stage('Artifactory Deploy') {
    options {
        timeout(time: 5, unit: 'MINUTES')
    }
    when {
        anyOf {
            branch "master"
            branch "develop"
        }
    }
    steps {
        withMaven(jdk: "${JDK_VERSION}", maven: 'M3') {
            script {
                def server = Artifactory.server('itext-artifactory')
                def rtMaven = Artifactory.newMavenBuild()
                rtMaven.deployer server: server, releaseRepo: 'releases', snapshotRepo: 'snapshot'
                rtMaven.tool = 'M3'
                def buildInfo = rtMaven.run pom: 'pom.xml',
                        goals: "--threads 2C --no-transfer-progress " +
                                "install --activate-profiles artifactory " +
                                "-Dmaven.repo.local=${env.WORKSPACE.replace('\\','/')}/.repository"
                server.publishBuildInfo buildInfo
            }
        }
    }
}

${env.WORKSPACE.replace('\\','/')} 是必需的，因为虽然 Linux 的行为符合预期，但 Windows 的行为显然类似于 T̪̩͑̒̀o̭̦̱͎̗̲̎̿̎ͩ̓̏̔n̊̀ͅy̲͓̘ͥͬ̾ͮ̌ͮ̐ ̘̪̝̳̺ ̖t̪͎̒̓͑̆̎̚h̵ͥͯ̅ͯ̚ş̟̩̞̹̫̌ͦ̉͂ͨ̔ͣͅ ̺͋̆͂̅ͥP̵̖̞͕̲̂̄ͥͩơ̙͇̫̰͍ͮ̽̓nͨ̄ͮyͨ ̘̪ͯ͂ͪ 关于路径分隔符。

我更愿意

withMaven(jdk: "${JDK_VERSION}", maven: 'M3', mavenLocalRepo: '.repository')

但我们不能拥有美好的东西。

无论如何，当在 Jenkins 上运行这个时，我收到以下错误:

并且没有任何 Artifactory 部署到 Artifactory(并且构建失败)。

如何解决这个问题？上游错误修复或本地解决方法。

在 Stack Overflow 上发布我的问题，因为我们拥有 Artifactory Pro 许可证，并且 Jfrog 的客户支持门户仅适用于 Pro X、Enterprise 和 Enterprise+ 客户。其他客户会被定向到 Stack Overflow，请参阅 https://jfrog.com/support/ .

Answer 1

可能的根本原因是在 GStringImpl cannot be cast to java.lang.String 的评论中发现的。 :

if you try to assign a GString to something that is statically typed as String (or pass a GString for a String-type method parameter) then Groovy will do the conversion for you, but if you assign to something that is typed as Object then you have to convert it yourself.

因为我在大括号中使用变量 (${env.WORKSPACE.replace('\\','/')})，所以我自动拥有一个 Groovy GString 而不是 Java String。

所以，Jfrog 工作人员，如果您正在监视 Stack Overflow 上的 artifactory 标记:根据 Jenkins documentation for the Artifactory plugin ， goals 被定义为 String 类型，但显然情况并非如此，因为 Groovy 无法进行转换？你能否证实或解释一下？谢谢!

编辑

我找到了Jenkins Artifactory Plugin API Javadocs和 the run() method of org.jfrog.hudson.pipeline.common.types.builds.MavenBuild采用 Map 作为参数:

public void run(Map<String,Object> args)

事实上，虽然 Groovy 会自动执行从 Groovy GString 到 Java String 的转换，但它不会执行从 Groovy Gstring 的转换 到 Map 内的 Object。

解决方法

如链接问题中所述，我添加了 .toString() 来手动将 Groovy GString 转换为 Java String。

所以

def buildInfo = rtMaven.run pom: 'pom.xml',
        goals: "--threads 2C --no-transfer-progress " +
                "install --activate-profiles artifactory " +
                "-Dmaven.repo.local=${env.WORKSPACE.replace('\\','/')}/.repository"

成为了

def buildInfo = rtMaven.run pom: 'pom.xml',
        goals: "--threads 2C --no-transfer-progress " +
                "install --activate-profiles artifactory " +
                "-Dmaven.repo.local=${env.WORKSPACE.replace('\\','/')}/.repository".toString()
