• 官方插件文档：https://help.sonatype.com/integrations/nexus-and-continuous-integration/nexus-platform-plugin-for-jenkins
• 安装插件：Pipeline Utility Steps

功能：

一、安装

二、配置

系统管理--> 系统设置--> Sonatype Nexus

三、使用

上传构建后的制品到Nexus的Hosted类型仓库中

Job

Declarative Pipeline

```bash
stage ('上传制品') {
steps {
    script{
    //读取源代码中的POM文件，获取生成制品的maven坐标信息（Jenkins需要安装pipeline-utility-steps插件）
    def pomfile = readMavenPom file: 'pom.xml'
    //使用Nexus Platform插件上传maven制品到Nexus的maven格式release仓库
    nexusPublisher nexusInstanceId: 'curiouser-okd-nexus', \
                    nexusRepositoryId: 'Maven-Releases', \
                    packages: [[$class: 'MavenPackage', \
                                mavenAssetList: [[classifier: '', extension: '', \
                                filePath: "target/${pomfile.artifactId}-${pomfile.version}.${pomfile.packaging}"]], \
                                mavenCoordinate: [artifactId: "${pomfile.artifactId}", \
                                                groupId: "${pomfile.groupId}", \
                                                packaging: "${pomfile.packaging}", \
                                                version: "${pomfile.version}"]]]
    //拼接maven制品的搜索链接,该链接是以源代码POM文件中的maven制品坐标信息参数对nexus api进行搜索，返回的response会重定向到制品的下载链接
    echo "The Jar Format Asset of Maven have been pushed to Hosted Repository: Maven-Release. The Download URL of the Asset: http://nexus-nexus.apps.okd311.curiouser.com/service/rest/v1/search../assets/download?maven.groupId=${pomfile.groupId}&maven.artifactId=${pomfile.artifactId}&maven.baseVersion=${pomfile.version}&maven.extension=jar&maven.classifier"
    }
}
}
```

四、注意

如果Job再次构建，产生相同的Jar，上传信息还是一样的，Nexus的Release仓库需要设置为"允许Redeploy"。不然，仓库中已经相同版本信息的制品，会造成上传失败
