React Native "Could not open settings remapped class cache"

Question

I received this error:

FAILURE: Build failed with an exception.

* What went wrong:
Could not open settings remapped class cache for 1a8j0dwq37525yzi9alfmzw3 (C:\Users\Username\.gradle\caches\5.4.1\scripts-remapped\settings_7z9efzwj1mz1b0w35o6u5p4ep\1a8j0dwq37525yzi9alfmzw3\settingsdcd040730888da95d185715568c9cc57).

Yesterday I tried to add the Google Login Package and received similar errors. Then I pulled a working version from my Github Repository and now I get this error. Already cleaned Gradle, reinstalled Java, deleted Cache, "Restart and delete" with Android Studio... Has anybody an idea?

Thanks in advance

Goto this directory :C:\Users\your username.gradle\caches Rename the gradle in question and then go and run 'react-native run-android' again your problem should be resolved!

For me, the removal of the cache didn't solve the problem.

I opened Android Studio and ran the Gradle build process. It downloaded the correct libraries and then react-native run-android ran flawlessly.

Had the same problem. Here's how i solved this.

Go to android > gradle > > wrapper > gradle-wrapper.properties file and find distributionUrl and at the end of that line you'll find gradle-5.2-all.zip kind of gradle version. This version can be diffrent in your case. just change it to latest gradle version. In my case latest version is 6.7 so i changed version like this. Before

distributionUrl=https\://services.gradle.org/distributions/gradle-5.2-all.zip

After

distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip
