Maven maven-deploy-plugin 总是上传两次

Question

我在将组件发布到 Nexus 存储库时遇到问题，Maven 上传文件两次：

第一次使用 maven-deploy-plugin groupId/artifactId/version 参数（这就是我想要的）
第二次使用 pom groupId/artifactId/version 参数（这是我不想要的）

我使用以下命令启动 packaging/deployment（请参阅底部的 pom.xml 文件）：

mvn clean package deploy:deploy-file -e -f pom.xml

这是处理部署阶段时 maven 输出控制台的片段（前 6 行是正确的，但请注意最后 2 行带有 pom groupId/artifactId/version）：

有解决办法吗？

感谢您的帮助。

使用命令行 mvn deploy:deploy-file -e -f pom.xml，效果很好（没有 clean package），但我需要在部署前打包...

Answer 1

maven-deploy-plugin 上传您指定的文件，然后上传所有项目附加工件。 maven-assembly-plugin 默认将输出文件附加到项目附加工件。这会使您上传两次。

修复是针对您的 maven-assembly-plugin 配置。
