java - Maven - 如何在使用 openjpa 插件时只运行一次编译目标

问题描述

当我运行时，mvn clean compile openjpa:enhance install我注意到compile目标运行了两次——在它之前openjpa:enhance和之后一次（也与resources），这导致增强的类openjpa:enhance被丢弃，因为它们被再次编译并重写。

如何更改 pom.xml 或mvn命令参数，使其不会运行compile两次，但之前只运行一次openjpa:enhance？install最后是需要的。

pom.xml：

解决方案

您需要添加openjpa:enhance到 POM 本身。然后你就跑mvn clean install。
