2:project ' XXX ' is missing required Java Project: ' YYYY '.

The corresponding jar can be found in the dependent jar, but there is still this error. In fact, the cause of the problem is not here. Please look down:

　　　　

Cause:

today in taking over a colleague to do a project, found that with MyEclipse deployment, the project has a lot of web pages appear Red Fork, one after the modification, the project should no longer show the Red fork, but it is strange that the project all the sub-files are not wrong, the project root directory has a red fork ... >_<</STRONG>! at the same time, a bunch of error appears in the problem of MyEclipse, prompting: Project ' XXX ' is missing required library: ' [path] \ Xxx.jar '.

Solve:

This occurs because there are duplicate and conflicting or address-referenced jar packages in your project's build path library, which can be resolved as follows:

① Right click on Project------> select Build path------> re-select Configure build path;
② Select the Library tab in the right window;
③ a jar package with duplicate, conflicting, or address errors found in the jar packages listed below (the normally problematic jar package displays a yellow warning) and is deleted;
④ Click OK to close the window, the problem will be resolved after eclipse or myeclipse automatically re-build workspace
