Error installing Ant: ANT_HOME is set incorrectly

Question

I read all the possible solutions but the none worked. I downloaded the ant and put it in C:\ant (so I have C:\ant\bin)

On Windows 7 under System variables I have variable called ANT_HOME with value

C:\ant

and variable called PATH with value

%ANT_HOME%\bin

And when I try in cmd (Command Prompt)

ant -version

I get

ANT_HOME is set incorrectly or ant could not be located. Please set ANT_HOME.

Also, if I try

echo %ANT_HOME%

I get

C:\ant

I tried PATH = %PATH%;%ANT_HOME%\bin but the same situation. Anyone?

EDIT:

Variables are (name - value):

ANT_HOME - C:\ant

Answer 1

Adding manually from Windows sometimes does not work...

To solve this, open command prompt and type these commands;

C:\>set ANT_HOME=C:\apache-ant-1.9.2
C:\>set JAVA_HOME=C:\jdk1.7.0_25
C:\>set PATH=%ANT_HOME%\bin;%JAVA_HOME%\bin

... then test:

C:\>ant -version 
Apache Ant(TM) version 1.9.2 compiled on JULY 8 2013

Answer 2

The trick is in avoiding spaces altogether!

Make sure that you don't add any unneeded spaces when adding to the PATH

PATH = %JAVA_HOME%\bin;%ANT_HOME%\bin

Answer 3

I had the same issue and I was able to fix it by defining the %JAVA_HOME%\bin variable before defining the %ANT_HOME%\bin in my Path.

CORRECT: Path %JAVA_HOME%\bin;%ANT_HOME%\bin;........

WRONG: Path %ANT_HOME%\bin;%JAVA_HOME%\bin;.......

Answer 4

Looks like there is an issue with apache-ant-1.8.3\bin\ant.bat.

Just comment the following lines in ant.bat and set the ANT_HOME environment variable and it should work.

if "%ANT_HOME%"=="" goto setDefaultAntHome

:stripAntHome
if not _%ANT_HOME:~-1%==_\ goto checkClasspath
set ANT_HOME=%ANT_HOME:~0,-1%
goto stripAntHome

:setDefaultAntHome
rem %~dp0 is expanded pathname of the current script under NT
set ANT_HOME=%~dp0..

Answer 5

In my case it was a silly mistake, when you download the file I did not realize was that the directory, apache-ant-1.9.3-bin and copy directly to Program Files/apache-ant-1.9.3-bin. This gave me the error, I solved it by copying the apache-ant-1.9.3 folder is inside apache-ant-1.9.3-bin to Program Files/apache-ant-1.9.3 and perform the usual steps.

Answer 6

I set up the environment variables for Java and Ant correctly but it didnt work till I restarted System. Set Environment variables ANT_HOME, JAVA_HOME and restart system.
