Recently, working on a Windows box, I had a problem where my ANT_HOME and ant -version result did not match. Problem resided in the order of path variables. ANT_HOME was declared last but when the system looks for a command in the path, it uses the first result it finds.

For example, the following was in my path:

  • C:\Windows\system32;
  • C:\Windows;
  • C:\Windows\System32\Wbem;
  • C:\Windows\System32\WindowsPowerShell\v1.0\;
  • C:\bea\weblogic92\server\bin;
  • C:\Program Files (x86)\Subversion\bin;
  • C:\oracle\instantclient_11_2;
  • C:\Program Files\TortoiseHg\;
  • C:\apache-ant-1.9.0\bin;
  • C:\Program Files (x86)\Git\bin;
  • C:\apache-maven-3.0.5\bin

As it can be seen, apache-ant-1.9.0 is almost the last one in the list. Little did I know that Weblogic folder contanied an older version of ant as well. I reordered my path, and everything worked like a charm afterwards.

The same thing can happen with Java. You have your JAVA_HOME set, but for some reason java -version returns a different version number. Check windows\system32\ folder, because java.exe might exist there as well. Add your Java location before windows\ path declarations.
