Jenkins管道中的工件:org.codehaus.groovy.runtime.GStringImpl不能转换为ja

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的行为如预期，但Windows的行为显然类似于T 794;̪͎̎hͥͯ关于路径分离器。

我更喜欢

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

但是我们不能有美好的东西。

无论如何，当在Jenkins上运行此程序时，我会得到以下错误：

并且没有工件被部署到Artifactory(并且构建失败(。

如何解决此问题？上游错误修复或本地解决方法。

在Stack Overflow上发布我的问题，因为我们有Artifactory Pro许可证，Jfrog的客户支持门户仅适用于Pro X、Enterprise和Enterprise+客户。其他客户直接访问Stack Overflow，请参阅https://jfrog.com/support/.

Answer 1

一个可能的根本原因是在GStringImpl的注释中发现了一些东西。无法将Impl强制转换为java.lang.String:

如果您试图将GString分配给静态类型为String的东西(或者为String类型的方法参数传递GString(，那么Groovy将为您进行转换，但如果您将Object类型的东西分配给它，那么您必须自己进行转换。

因为我使用的是大括号中的变量(${env.WORKSPACE.replace('\','/')}(，所以我会自动使用GroovyGString而不是JavaString。

所以，Jfrog的工作人员，如果您正在监视Stack Overflow上的artifactory标记：根据Artifactory插件的Jenkins文档，goals被定义为类型String，但显然不是这样，因为Groovy不能进行转换？你能确认或解释一下吗？谢谢

编辑

我找到了Jenkins Artifactory插件API Javadocs，org.jfrog.hudson.pipeline.common.types.builds.MavenBuild的run()方法以Map为参数：

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

事实上，虽然Groovy将自动完成从GroovyGString到JavaString的转换，但它不会在Map中完成从GroovyGstring到Object的转换。

解决方案

如链接问题中所述，我添加了.toString()以手动将GroovyGString转换为JavaString。

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

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()
