What does "red cross" on project icon mean in Eclipse?
提问by Ahsan
After some code modifications, I suddenly noticed the project icon has a small red cross icon. However, no other file/package/folder is showing this icon. I am not sure where the error is and how to solve it.

Usually it means that there's a path error, eg. one jar referenced in the project cannot be found.
通常这意味着存在路径错误，例如。找不到项目中引用的一个 jar。

This kind of problem usually happens when you are using maven project. To solve this right click on the project, go to maven and select update project. The red cross icon will go.
这种问题通常在您使用 maven 项目时发生。要解决此问题，请右键单击项目，转到 maven 并选择更新项目。红十字图标将消失。
