Invalid revision: 3.18.1 CMake in Android Studio

  android, c++, cmake, version

This is not a question, it is a solution for a technical problem with android studio which I have meet. I will share my doing to fix the error if any one would encounter.
The brief error message is: "Invalid revision: 3.18.1-g262b901", while 3.18.1 is latest CMake version in Android studio. But the problem is my project is old and it builds failed with this CMake version. There are 2 solutions, you can choice 1 in 2:
Remove(uninstall) CMake version 3.18.1: Click Android Studio->Preferences->Appearance & Behavior->System Settings->Android SDK->SDK Tool->(enable the Show Package Details checkbox)->CMake->Uncheck 3.18.1 checkbox, then click Apply button in right-bottom conner of dialog.
Set directory path of lower-version CMake in the file by adding this line to this file: cmake.dir=/Users/admin/Library/Android/sdk/cmake/ (The CMake path can be different in your computer)

Long error message(a small part):


at org.gradle.configuration.project.LifecycleProjectEvaluator.addConfigurationFailure(
    at org.gradle.configuration.project.LifecycleProjectEvaluator.notifyAfterEvaluate(
Caused by: java.lang.NumberFormatException: Invalid revision: 3.18.1-g262b901

Hope it help!
