“Unable to locate tools.jar” when running ant [duplicate]

Answer 1

I was also having the same problem So I just removed the JDK path from the end and put it in start even before all System or Windows 32 paths.

Before it was like this:

C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Program Files\doxygen\bin;%JAVA_HOME%\bin;%ANT_HOME%\bin

So I made it like this:

%JAVA_HOME%\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Program Files\doxygen\bin;%ANT_HOME%\bin
