I have taken a clone of the existing repo and installed the latest Android tools for my React Native project. Now the project is up and running on my system. But I have made changes to the following files without intending it.
1) app/build.gradle :
-buildToolsVersion "25.0.2"
+buildToolsVersion '26.0.1'
2) android/ build.gradle
-classpath 'com.android.tools.build:gradle:2.2.2'
+classpath 'com.android.tools.build:gradle:2.3.3'
3)android/gradle/wrapper/gradle-wrapper.properties
-distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip
+distributionUrl=https://services.gradle.org/distributions/gradle-3.3-all.zip
I want to undo/checkout these changes (Probably might have to downgrade some of the tools). Need a safe way to do this. Thank you.
