Jenkins 管道中的 Artifactory：org.codehaus.groovy.runtime.GStringImpl 不能转换为 java.lang.String

Question

我有这个Jenkinsfile：

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 显然表现得像 T?????o?????????????n???y?????????? ？？？？？？这？？？？？？？？？？？？？？？？？？？？小马？？？？？？关于路径分隔符。

我宁愿有

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

但我们不能有好东西。

无论如何，在 Jenkins 上运行它时，我收到以下错误：

并且没有工件被部署到 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 上发布我的问题是因为我们拥有 Artifactory Pro 许可证，而 Jfrog 的客户支持门户仅适用于 Pro X、Enterprise 和 Enterprise+ 客户。其他客户被定向到 Stack Overflow，请参阅https://jfrog.com/support/。

Answer 1

一个可能的根本原因是在GStringImpl的评论中发现的东西不能转换为 java.lang.String：

如果您尝试将 a 分配给GString静态类型为 as 的内容String（或GString为String-type 方法参数传递 a ），则 Groovy 将为您进行转换，但如果您分配给类型为 as 的内容，Object则必须自己进行转换.

因为我在花括号 ( ${env.WORKSPACE.replace('\\','/')}) 中使用了一个变量，所以我会自动使用 GroovyGString而不是 Java String。

所以，Jfrog 员工，如果您正在artifactoryStack Overflow 上监控标签：根据Artifactory 插件的Jenkins 文档，goals被定义为 type String，但显然情况并非如此，因为 Groovy 无法进行转换？你能确认或解释吗？谢谢！

编辑

我找到了Jenkins Artifactory Plugin API Javadocs和将 a作为参数的run()方法org.jfrog.hudson.pipeline.common.types.builds.MavenBuildMap：

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

因此，确实，虽然 Groovy 会自动执行从 GroovyGString到 JavaString的转换，但它不会执行从 GroovyGstring到Object内部Map.

解决方法

如链接问题中所述，我添加.toString()手动将 Groovy 转换GString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"

变成了

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()
