编译单元不在Java项目的构建路径--Maven [英] The compilation unit is not on the build path of a Java project - Maven

问题描述

今天我在我的日食中导入了一个Maven项目。当我尝试去Auto建议时，当我添加一些代码时，它会提醒我：编译单元不在Java项目的构建路径上。我看到这个问题的解决方法很少，但没有一个解决。这个应该做什么？

Today I've imported a Maven project in my eclipse. When I try to go for Auto suggest, when I was adding some code, it alerts me as "The compilation unit is not on the build path of a Java project". I saw few workarounds for this issue, but none of them solved. What should be done for this one?

推荐答案

当您在Eclipse中打开多模块Maven项目您在项目资源管理器中看到通常

When you open a multi-module Maven project in Eclipse you see in the project explorer normally

- parent-module
  - sub-module1
    - src
      - main
        - java
          - YourClass <-- the one with the framed J icon
  + sub-module2
- sub-module1
  - src
    - main
      - java
        - YourClass <-- the one with the solid J icon
