There was a problem with creating a new Android project in Eclipse: Plug-in Org.eclipse.ajdt.ui was unable to load

New Android Project area cannot be created after opening in Eclipse, the following prompt dialog box appears:

Plug-in Org.eclipse.ajdt.ui was unable to load class Org.eclipse.ajdt.internal.ui.ajde.CachedRuntimeClasspathEntryResolver.

Baidu causes after finding the solution: Re-create the workspace can be used normally. (I did not execute but deleted all the works in eclipse after restarting Eclipse.) However, the problem with this method is that this kind of problem will occur later.

Here's another way to find it online: Uninstall the ADJT plugin and the AspectJ plugin.

First, open the path where eclipse is located, such as E:\eclipse, and locate the Plugins folder, sorted alphabetically. Then find a folder similar to the following

Delete and remember to back up when deleting. ：

org.aspectj.aspectjweaver_1.5,

org.eclipse.ajdt.pde.build_1.5.0,

org.aspectj.ajde_1.5.4,

org.aspectj.aspectjrt_1.5,

org.eclipse.ajdt.examples_1.5.0 ,

org.eclipse.ajdt.source_1.5.0
