Android Studio error ➡ Cannot run program "git" ... CreateProcess error=2, The system cannot find the file specified

The problem is that gradle cannot find git in the path. If you turn on the compiler options in Android Studio --stacktrace --debug you get more information on this.

Here is part of the stacktrace:

Caused by: java.io.IOException: Cannot run program "git" (in directory "..."): CreateProcess error=2, The system cannot find the file specified

The solution is to install git and add the location of the binary to the path. I experienced this issue on Windows when opening a project originally created on Mac OS X.

1. Close Android Studio

2. On Windows open up System Properties > Advanced > Environment Variables...

3. Click 'Path' and then click edit

4. At the end of the 'Variable Value' add something like ';C:\Program Files\Git\cmd' (but without the quote of course). Don't add this: ';"C:\Program Files\Git\cmd"' because it won't work. This was the issue I was having.

5. Open Android Studio, clean, and build again and you should be up and running.

I was working with Android-ObservableScrollView and I encountered the same problem with you. This is how I fixed that:

build.gradle (project):

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}


allprojects {
    repositories {
        jcenter()
    }
}

build.gradle (sample):

//project.ext.gitHash = "git rev-parse --short HEAD".execute().text.trim()
