Maven父子项目问题

Question

我有父项目 - selenium 和子项目作为项目 1，我的意图是让所有可重用的类在父项目中并在子项目中测试。当我尝试从子项目运行测试时，出现以下错误，可以请帮帮我。”未能在项目 project1 上执行目标：无法解析项目 com.aero:project1:pom 的依赖项： 1.0-SNAPSHOT：无法解析以下工件：com.automation:parentproject:jar:1.0-SNAPSHOT”。我首先在父项目和子项目尝试 mvn clean 和 mvn install 然后执行 mvn surefire:test 但得到上述异常.
注意：当我第一次构建父项目时，它不会在 .M2 路径中生成 .jar 文件

Answer 1

1- 你的孩子 pom 引用了错误的父工件。

2- 应该删除对“parentproject”的直接依赖，因为它的父项而不是依赖项。
