Error: Execution failed for task ': app: transformClassesWithDexForRelease' occurs during androidstudio packaging. solution,

When packaging a project on android studio today, I encountered the Error: Execution failed for task ': app: transformClassesWithDexForRelease. I remember that I encountered this problem before, but how can I not remember how to solve the problem? I had to check the information on the Internet again, and finally solved the problem.

The reason for this problem is very simple, because the jar packages applied in my project are repeated, and I am building. the dependencies in the gradle file repeatedly depends on the jar package in libs. just delete the following.
