If you receive Tools.jar not found error, go to “D:/Ant/manual/api/org/apache/tools/ant/util/JavaEnvUtils.html” and replace “java.home” with “java_home”.

Or

Move the Tools.jar from JDK to JRE location as specified in the error.

Best solution is the first one to replace  “java.home” with “java_home”.

Cheers!!!
