React Native——无法确定任务“：app:mergeDebugAssets”的依赖关系

Question

I'm trying to run my project with the npm run android command and it throws this error for me:

info Running jetifier to migrate libraries to AndroidX. You can disable it using "--no-jetifier" flag.
Jetifier found 1579 file(s) to forward-jetify. Using 12 workers...
info Starting JS server...
info Installing the app...
Configuration on demand is an incubating feature.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.2/userguide/command_line_interface.html#sec:command_line_warnings

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:mergeDebugAssets'.
> You must specify a URL for a Maven repository.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup. Run CLI with --verbose flag for more details.
Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081

what I did so far is cd to the android folder and run ./gradlew clean and it says BUILD SUCCESSFUL with no error also I delete my node_module folder and run npm install again but no luck. I appreciate any help.

I had a similar error, in my case I edited my android/build.gradle file like this:

after

...
jcenter()

add line

mavenCentral()

Don't know if it help in your case, but it worked for me

PS as I understand there is some problems with access some files at https://jcenter.bintray.com/
