maven deploy:此项目的打包未将文件分配给构建工件

Question

我正在尝试将maven项目部署到远程存储库.

mvn install适用于本地存储库.

我正在使用Groovy和Groovy-Eclipse编译器插件.我试图运行mvn deploy来部署到远程存储库,我收到以下错误:

The packaging for this project did not assign a file to the build artifact -> [Help 1]

这是我的pom.xml:

我是否需要在构建步骤中添加一些内容？

Answer 1

你需要运行mvn deploy而不是mvn deploy:deploy.前者执行maven 生命周期直到"部署"阶段,即它编译代码,将其打包到JAR文件中,最后将其部署到远程存储库.

mvn deploy:deploy另一方面,只执行deploymaven-deploy-plugin 的目标.如果没有先前执行的生命周期阶段(生成实际构建工件(JAR文件))的上下文,maven-deploy-plugin就没有任何可以部署的内容并且会因错误而中止The packaging for this project did not assign a file to the build artifact.maven-deploy-plugin 的FAQ中也解释了这种行为.
