问题描述
当我运行 mvn clean compile openjpa:enhance install 时，我注意到 compile 目标运行两次 - 一次在 openjpa:enhance 之前和之后（还有 resources），这会导致 {{1} 的增强类}} 被丢弃，因为它们被再次编译和重写。
如何更改 pom.xml 或 openjpa:enhance 命令参数，使其不会运行 mvn 两次，而是只在 compile 之前运行一次？需要末尾的 openjpa:enhance。
pom.xml:

的输出：
mvn clean compile openjpa:enhance install解决方法
您需要将 openjpa:enhance 添加到 POM 本身。然后你只需运行 mvn clean install。
