online solution

The Android SDK Build-tools version does not match. Go to the Settings of the AS to download the SDK-related configuration you need, but it does not work for me.

java - No variants found for 'app'. Check build files to ensure at least one variant exists: Android Studio - Stack Overflow

Sharing my workaround:

repositories {
        flatDir {
            dirs 'libs'
        }
//        maven {
//            url "http://dl.bintray.com/jlmd/maven"
//        }
    }

2、manifest merger failed with multiple errors see logs

Go to Terminal and enter the following command to view the specific Log

 ./gradlew processReleaseManifest --stacktrace

Solution: In addition to adding attributes to the manifest file, please check the project and Model and the three-party dependent SdkVersion versions to keep as consistent as possible

3、module java.base does not “opens java.io“ to unnamed module

Add the following code

maven {
            url "https://jitpack.io"
        }
        mavenCentral()
