Eclipse`org.springframework中的Maven项目无法从目标路径解析为类型` [英] Maven Project in Eclipse `org.springframework cannot be resolved to a type` from target path

问题描述

我已经进入了一个Maven项目，当我从命令行运行mvn clean install时，它可以正常运行.在我精简系统之前的一周中，我在Eclipse中显示了该项目而没有错误.这使我认为我的配置有误，希望有人可以给我进行健全性检查.

I've rolled onto a maven project that when I run mvn clean install from command line builds and runs fine. I had this project displaying in Eclipse without errors earlier in the week before I hosed my system. This makes me think I have a configuration wrong and hoping someone can give me a sanity check.

在Eclipse内，我在<project_path>/target/<project>-<version>/WEB-INF/...这样的路径中的文件中看到与org.springframework cannot be resolved to a type相关的错误，引起我注意的是target的路径，该路径是派生文件夹.

Inside of Eclipse, I'm seeing reported errors related to org.springframework cannot be resolved to a type in files in paths like <project_path>/target/<project>-<version>/WEB-INF/... What is catching my eye is that path of target which is a derived folder.

项目资源管理器视图:

从上面的屏幕截图中，您可以看到相关的jar文件已从maven依赖项中正确提取.关于配置错误以及为什么我从目标路径中看到错误的任何想法?

From the above screenshots, you can see that the related jar files are pulled properly from the maven dependencies. Any ideas on what I have misconfigured and why I'm seeing the errors from the target path?

推荐答案

build和WebContent文件夹表明您没有正确地将Maven项目导入Eclipse，因此会出错.

The build and WebContent folders indicate that you haven't properly imported Maven project into the Eclipse, hence errors.

解决此问题的方法之一:

One of the way to fix this:

• 从Eclipse删除项目.

• Delete project from the Eclipse.

转到项目文件夹，然后删除所有不需要的文件夹. (请保留src).

Go to project folder and delete all not needed folders. (Leave src).

转到Eclipse，单击File-> Import...，选择Existing Maven Projects，选择项目文件夹Finish.

Go to Eclipse click File -> Import..., select Existing Maven Projects, select your project folder, Finish.
