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

问题描述

当我尝试使用 ctrl + space 时，会显示此错误：

When I try to use ctrl+space this error is shown:

This compilation unit is not on the build path of a Java project.

我看到有类似的主题，但我的工作环境是Eclipse，我从Git（我导入项目作为一般项目），我使用Apache Ant。任何人都可以帮助我吗？

I see that there are similar topics but my work environment is Eclipse and i pull my project from Git (I import project as general project) and i use Apache Ant. Can anyone help me?

推荐答案

由于您将项目导入总体项目，因此不具有java性质

Since you imported the project as a General Project, it does not have the java nature and that is the problem.

在工作区的.project文件中添加以下行，并刷新。

Add the below lines in the .project file of your workspace and refresh.

<natures>
      <nature>org.eclipse.jdt.core.javanature</nature>
</natures>
