使用jenkins管道脚本将pom上传到Nexus仓库

Question

有人可以帮我编写多分支管道脚本来构建，生成POM并将其导出到NEXUS2存储库吗？

我尝试过下面的代码，但是得到了arrayIndexOutofBoundException

与此同时，我在管道脚本中创建了构建和测试报告，除了下面的代码外，它运行正常

environment {
        // This can be nexus3 or nexus2
        NEXUS_VERSION = "nexus3"
        // This can be http or https
        NEXUS_PROTOCOL = "http"
        // Where your Nexus is running
        NEXUS_URL = "Nexus_url"
        // Repository where we will upload the artifact
        NEXUS_REPOSITORY = "repository-example"
        // Jenkins credential id to authenticate to Nexus OSS
        NEXUS_CREDENTIAL_ID = "nexus-credentials"
    }


    stage("publish to nexus") {
            steps {
                script {
                    // Read POM xml file using 'readMavenPom' step , this step 'readMavenPom' is included in: https://plugins.jenkins.io/pipeline-utility-steps
                    pom = readMavenPom file: "pom.xml";
                    // Find built artifact under target folder
                    filesByGlob = findFiles(glob: "target/*.${pom.packaging}");
                    // Print some info from the artifact found
                    echo "${filesByGlob[0].name} ${filesByGlob[0].path} ${filesByGlob[0].directory} ${filesByGlob[0].length} ${filesByGlob[0].lastModified}"
                    // Extract the path from the File found
                    artifactPath = filesByGlob[0].path;
                    // Assign to a boolean response verifying If the artifact name exists
                    artifactExists = fileExists artifactPath;
                    if(artifactExists) {
                        echo "*** File: ${artifactPath}, group: ${pom.groupId}, packaging: ${pom.packaging}, version ${pom.version}";
                        nexusArtifactUploader(
