Answer 1

why don't you try the 32 bit version. there could be a problem between the two versions you have installed being 32 and 64. try the 32 bit version so ur not seeing any 64 bit versions.

it should fix ur problem.

Answer 2

I was getting a "C:\Program" is not recognized as an internal or external command, operable program or batch file error, when running %ANT_HOME%\bin\ant.bat

I found that I needed to wrap the command in double-quotes in order to get the proper escaping to happen on the path string.

FIX: "%ANT_HOME%\bin\ant.bat" --NOT-- %ANT_HOME%\bin\ant.bat

Hope that helps!

Answer 3

I had this problem on a 64-bit Windows 7 machine and Ant 1.8.2. The solution was to use the admin tools mentioned by #bigfix to set the environment variables. Follow the Ant installation instructions for Windows. But do not set the path as %ANT_HOME%\bin. Instead, use an explicit path such as C:\jdk-1.5.0.05\bin.

My first test failed because my command window was already open and using the old env vars. Close it and open a new one. Then try the test. It worked for me.

Answer 4

I solved the problem by creating system variable JAVA_HOME to C:\Program Files\Java\jdk1.6.0_25. Don't put the semi colon after it. First of all I put the semi colon and there was an error. I removed the semi colon and it worked.

Answer 5

I am going to add one other issue that I had with this.

BTW, the answer here worked for me too. I had to point my java directory to the specific SDK version. Thank you very much.

But I'm going to add that I had to install the SDK as an administrator, or it didn't extract tools.jar. I found this answer elsewhere, and I hope it helps someone to repeat it here.

Answer 6

All you need is to set JAVA_HOME path in your environment. In Windows 7 go to "System Properties -> Advanced -> Environment Variables" and add JAVA_HOME. The value in my case was:

C:\Program Files\Java\jdk1.7.0_07

This resolved the issue for me. This variable points Ant to the correct Java location.
