Failed to import new Gradle project: failed to find Build Tools revision *.0.0

After spending a few hours: I restarted the Android SDK Manager and at this time I noticed that I got Android SDK Platform-tools (upgrade) and Android SDK Build-tools (new).

After installing those, I was finally able to fully compile my project.

Note: The latest ADT (Version 22) should be installed.

This is what I had to do:

1. Install the latest Android SDK Manager (22.0.1)
2. Install Gradle (1.6)
3. Update my environment variables:
   • ANDROID_HOME=C:\...\android-sdk
   • GRADLE_HOME=C:\...\gradle-1.6
4. Update/dobblecheck my PATH variable:
   • PATH=...;%GRADLE_HOME%\bin;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools
5. Start Android SDK Manager and download necessary SDK API's

As of May 2020, A really straightforward solution using Android Studio:

1. Open Android Studio
2. From the top, choose File > Settings > Appearance & Behavior > System Settings > Android SDK
3. click on the tab SDK Tools at the top. Then highlight Android SDK Build Tools from the list.
4. Check "Show Package Details" check box, choose the build tools version you need and then click Apply.

Look in the SDK Manager what is your highest Android SDK Build-tools version, and copy this version number in your project build.gradle file, in the android/buildToolsVersion property (for me, version was "18.1.1").

Hope it help!
