Secondly, you can enter gradlew processDebugManifest --stacktracethis command and you will know that this is printing the tracking information of the processDebugManifest execution process, so when other errors occur in the build, as long as you find the program that throws the error, and then replace processDebugManifest, you can also get the corresponding tracking information. For

. This problem is relatively rare. I worked on it for a long time and could not find the reason. Later, I was about to collapse and came up with a method. I created a new empty project. Then which empty project will create a manifest in unityLibrary, and then I copy the manifest of the new project, and it's ok! (PS: It didn’t work once during my period. It said my key was wrong, so I closed the key and repackaged it.)

Use this command line to print out more log information
gradlew compileDebug --stacktrace
