I am on 64-bit machine and have installed JDK 8 64-bit. The following are my system path variables:

ANT_HOME: C:\Users\aniruddha.b\AppData\Roaming\npm\node_modules\ant\ant
JAVA_HOME: C:\Program Files\Java\jdk1.8.0_20
CLASSPATH: C:\Program Files\Java\jdk1.8.0_20\lib

PATH: %JAVA_HOME%\bin;
C:\AndroidSDK\adtbundle\sdk\platform-tools;
C:\AndroidSDK\adtbundle\sdk\tools;
C:\Program Files\nodejs\;
%ANT_HOME%\bin;

My Project path is: D:\\LWMobile\\hello

"hello" is the project folder

Answer 1

The issue was with the incompatibility of the Ant version with my Java version.

Ant version I have is 1.8.4. Initially, I had JDK 8 - which supports only Ant 1.9 & greater

Therefore, I uninstalled JDK8 and reverted back to JDK7

Yes, I could have rather updated Ant itself. That is also an option. However, I particularly needed Ant1.8

Answer 2

The issue is with the incompatibility of the Ant version with your Java version.

Ant version you have is 1.8.4. JDK 8 - supports only Ant 1.9 & greater

Uninstall JDK8 and revert back to JDK7
