Answer 1

This could be caused by broken gradle installation or slow internet.

Solution:

Delete the .gradle folder located at Windows: C:\Users\<user>\.gradle or Mac: /home/<user>/.gradle

and then run the flutter app again.

It might take a little longer because gradle dependencies will be downloaded again. Don't disconnect your device.

This is correct answer for question and needs to be marked as answer. I had same problem and it solved it! – Maturation

If deleting the .gradle folder doesn't work for everyone. You can try switching to your mobile data and try running the application. It worked for me, you can find the reference here. – Domoniquedomph

Answer 2

This is how to fix this.

• Just delete the .gradle folder in your user directory
• The command in linux or MacOS is rm -r $HOME/.gradle/
• Then open your project directory and then navigate to android folder
• Finally, run ./gradlew
• This will force gralde to redownload all dependencies needed
• That's it ,

Happy coding ✨🎉🎉🎉

Answer 3

Try to install gradle manually (https://services.gradle.org/distributions/gradle-4.6-bin.zip), and unzip it

Open <path_to_flutter_app>/android/gradlew

Find: CLASSPATH=$APP_HOME/gradle/wrapper/gradle-wrapper.jar and replace with: CLASSPATH=<path_to_downloaded_gardle>/gradle-4.6/lib/gradle-launcher-4.6.jar

Find: exec "$JAVACMD" "${JVM_OPTS[@]}" -classpath "$CLASSPATH" org.gradle.wrapper.GradleWrapperMain "$@"

and replace with: exec "$JAVACMD" "${JVM_OPTS[@]}" -classpath "$CLASSPATH" org.gradle.launcher.GradleMain "$@"

flutter run

Catchword

Answer 4

A gradle process could be holding a file handle in the .gradle folder. What worked for me is killing all java processes.
