Command failed: gradlew.bat installDebug

How I solved this problem:

First, make sure that I have %java_home% variable set and also %path% has the java sdk included.
How to setup Java environment variables

Second, Go to your android folder and run this command:

C:\Projects\myproject\android>gradlew.bat app:installDebug.

As you can see that my gradle download is corrupt. All you have to do is delete this folder and rerun the command.

C:\Projects\myproject\android>gradlew.bat app:installDebug
