1、报错截图如下：

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project common: Failed to retrieve remote metadata com.xintian:common:0.0.1-SNAPSHOT/maven-metadata.xml: Could not transfer metadata com.xintian:common:0.0.1-SNAPSHOT/maven-metadata.xml from/to nexus (http://localhost:8081/repository/xt-release/): transfer failed for http://localhost:8081/repository/xt-release/com/xintian/common/0.0.1-SNAPSHOT/maven-metadata.xml, status: 400 Repository version policy: RELEASE does not allow metadata in path: com/xintian/common/0.0.1-SNAPSHOT/maven-metadata.xml

其他配置如图：

解决方案：

试了好久，一度以为是私服搭建的有问题，最终发现竟是jar包版本号的问题，如果上传的路径是 release，则该版本号不能是以 SNAPSHOT 结尾的，可以为空，也可以改为RELEASE。
