Just downloaded the latest version of Ant and installed at:
C:\apache-ant-1.8.4
I added the following to the Env Path variable:
...;C:\apache-ant-1.8.4\bin
When I open a terminal window and type:
ant -version
I get:
Files\Java\jdk1.7.0_07"" was unexpected at this time.
In System variables I have the variable JAVA_HOME set to:
"C:\Program Files\Java\jdk1.7.0_07"
so it appears that "ant -version" is struggling to read the space in JAVA_HOME even though it is in quotes.
I see an alternative post on this topic:
Ant and Eclipse
but it doesn't tackle this specific point.
Has anyone else encountered this problem and know the answer?
My guess is current definition of JAVA_HOME has unwanted double quotes. Show output of set JAVA_HOME on command window. It should not have any double quotes.
Please start command prompt. Set the JAVA_HOME again
set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07
Hmmm, it should be fine with quotes. Could be something else in your path. If all else fails you could revert to dos 8.3 notation.
dir /x
Which gives
13/01/2013 03:57 PM <DIR> PROGRA~1 Program Files
13/01/2013 03:57 PM <DIR> PROGRA~2 Program Files (x86)
In case anyone else is still encountering this problem, I am on Windows 7 and was experiencing the same. I was using the GUI provided by right-clicking the "computer" icon to attempt to set the JAVA_HOME path to the relevant program files folder (C:\Program Files (x86)\Java\jdk1.7.0_45). This will not work! The GUI doesn't accept spaces in paths. Command line however, does. Use set JAVA_HOME= C:\Program Files... to get it working, filling out the rest of the path with the location of your jdk installation.

Because I was having problems, I opened a command window and changed to the very bin directory where ant was installed. Then I entered 'ant -version'. It returned:
Files\Java\jdk1.8.0_72"" was unexpected at this time.
Entering 'ant' alone gives the same message. The JAVA_HOME is set to the jdk folder (jsk1.8.0_72), and the PATH adds \bin to it. Nothing else appears broken.
Any ideas gratefully received. Thank you.
Since writing the above, I tried shifting to 32-bit jdk7 from 64-bit jdk8. Output from "ant --version" changed a bit to: Files was unexpected at this time.
Changing the Symlinks in C:\ProgramData\Oracle\Java\javapath did nothing good.
Output of "set | findstr /b /i //"java_home=//"" is:
JAVA_HOME="C:\Program Files (x86)\Java\jdk1.7.0_79"
For PATH=, the output is too long and characters could be missed, so instead I ran: echo %PATH% > d.txt. Here is the result:
C:\Program Files\Everything;C:\Program Files\gradle-2.8\bin;"C:\Program Files (x86)\Launch4j";C:\Program Files (x86)\Apache\apache-ant-1.9.6\bin;"C:\Program Files (x86)\Java\jdk1.7.0_79"/bin;C:\cygwin64;C:\cygwin64\bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Windows Resource Kits\Tools\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files\curl;C:\Devkit\bin;C:\Ruby21-x64;C:\Ruby21-x64\bin;C:\Perl64\site\bin;C:\Perl64\bin;C:\Program Files (x86)\Apache\apache-ant-1.9.0\bin;"C:\Program Files (x86)\Java\jdk1.7.0_79"\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\GNU\GnuPG\pub;C:\Program Files (x86)\WinMerge;C:\Program Files (x86)\Bazaar;C:\Program Files\jEdit;C:\Program Files (x86)\Groovy\Groovy-2.1.7\bin;C:\Program Files\MySQL\MySQL Server 5.1\bin;C:\Program Files (x86)\Calibre2\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\CMake\bin;C:\Program Files (x86)\mingw-w64\i686-4.9.2-posix-dwarf-rt_v4-rev2\mingw32\bin;C:\Program Files (x86)\Scite\scite\bin;C:\Program Files (x86)\nodejs\;C:\Program Files (x86)\Git\cmd;C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\;C:\Program Files\Microsoft SQL Server\120\Tools\Binn\;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Tcl\bin;C:\Program Files (x86)\Arduino\hardware\tools\avr\bin;C:\Program Files\dbd\Beard;C:\Program Files\dbd\dd;C:\Users\dbd\AppData\Roaming\npm
Please note that all the Java Demos run OK, suggesting that the basic java installation is OK.. Have not yet looked at the Registry. All of this is mysterious and upsetting.
Thanks to Stefan De Laet and Chad Nouis. More to be done.
This entry in your PATH doesn't look quite right:
"C:\Program Files (x86)\Java\jdk1.7.0_79"/bin
Those quotation marks shouldn't be there. Also, the forward slash before bin should be replaced with a backslash:
C:\Program Files (x86)\Java\jdk1.7.0_79\bin
Next, the JDK directories appear twice in your PATH:
...;"C:\Program Files (x86)\Java\jdk1.7.0_79"/bin;...;"C:\Program Files (x86)\Java\jdk1.7.0_79"\bin;...
Only one JDK directory is necessary. I recommend deleting the second entry.
Further, your JAVA_HOME also shouldn't have quotation marks. The following...
JAVA_HOME="C:\Program Files (x86)\Java\jdk1.7.0_79"
...should be...
JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_79
At long last and finally, 'ant -version' gets the correct response: "Apache Ant(TM) version 1.9.6 compiled on June 29 2015". I beiieve several things contributed to the success:
Switching from 64-bit to 32-bit java. Since Ant comes as a zip file, I could not discover whether it is really 64-bit or 32-bit. I did find it in my 32-bit folder, but that could be a holdover from earlier times. But maybe not.
fixing the PATH. The PATH which I sent was an end-result after substitution composed of a replacement for the following: "...%JAVA_HOME%/bin...". Normally, I would have spotted it, but because of the %, I did not. Thank you Chad Nouis! When I switched to 32-bit, I did not touch the PATH entry, but merely changed JAVA_HOME. This may have been in the system for some time.
Oh Well! Have a good day everyone and thanks again!
I tried various ant versions and also tried running the command directly from ant_home/bin directory, but no luck only below error:
ant error "The syntax of the command is incorrect." on running ant.bat
kindly help on this, I am not finding anything helpful anywhere on the web.
Thanks
Luckily I got the problem root cause and solved it :)
The reason was my java_home was ending with a " character in environment variable, after removing the " from java_home path, ant started working as expected.
to investigate the aforesaid I just opened the ant.bat in notepad and in the first line I changed echo "off" to echo "on", by doing that, when I hit ant.bat in the command prompt it logged the exact line of ant.build file where the aforesaid error was being thrown.
I have JAVA_HOME set with proper path but it was pointing to JDK 1.8. I need to change it to point to JDK 1.6 in order to resolve the issue.
The ANT_HOME and JAVA_HOME environment variables are configured in some user machines with "" surrounding the paths, to overcome the spaces in the folder paths.
Having the folder paths with "" around them could be the reason for the message. Either the quotes are to removed or the multiple paths are to separated by ";"

I am trying to compile some java code on Windows 7 pc, I have installed java JDK and I am trying to use the javac command in cmd but I get output saying that
'javac' is not recognized as an internal or external command,
operable program or batch file.
What do I have to do to enable compiler in cmd or is it possible to do in Windows?
1)Go to properties by right click on icon Computer , then navigate to Advanced System Settings.
2)Click Environment Variables.
3)Click on New , set Variable name as path and Variable path as the path of java jdk installation directory which could be something like this -
C:\Program Files\Java\jdk1.6.0_23\bin;
where C:** is the drive where JDK is installed and **Program Files\java is the directory where it resides.
look out for semi-colon(;) at the last.
4)Click ok
5)Restart cmd and run javac , it should work now.
Look for Screenshots here for more help.

you have to set a new system variable for your JAVA_HOME in windows.
See here for further information.
Add the path to bin folder of JDK in your PATH variable. For instructions to set PATH variable follow this tutorial.
Your java directory is not on the path. Here are some helpful screenshots to show how to set it up:

I have been trying to install Maven v 3.0.4 on my machine win 7 for the first time.I have a problem setting the path environment System variable I have the following 4 entries :
PATH
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Java\jdk1.7.0_04;C:\Program Files\apache-maven-3.0.4\bin;M2_HOME;%M2%
M2_HOME
C:\Program Files\apache-maven-3.0.4\bin
M2
%M2_HOME%\bin
JAVA_HOME
C:\Program Files\Java\jdk1.7.0_04\bin
when I do mvn --version
I get the error:
JAVA_HOME not found in your environment, please set the JAVA_HOME variable in your environment to match the location of your java installation
The java -version displays the java version fine,
what am I doing so horribly wrong? Is the PATH ok?
Help appreciated, thanks.
It is only necessary to set the path to the Maven binary and to the JDK correctly:
set PATH %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Java\jdk1.7.0_04\bin;C:\Program Files\apache-maven-3.0.4\bin
Furthermore you need to set the JAVA_HOME correctly which is done under windows like this:
SET JAVA_HOME=C:\Program Files\Java\jdk1.7.0_04
Be aware of setting JAVA_HOME to the root of the installed JDK and not to bin folder it.
The settings of M2 and M2_HOME is not necessary.
from command prompt run the following
set M2_HOME= C:\Program Files\apache-maven-3.0.4
set PATH=%PATH%;%M2_HOME%\bin
set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_04
set PATH=%PATH%;%JAVA_HOME%\bin
cmd.exe
mvn -version
The environmental variables should point to the installation directory of each program respectively, and their corresponding bin folders should be added to the PATH:
Make sure that your JAVA_HOME points to the C:\Program Files\Java\jdk1.7.0_04 (or whatever directory you have installed your JDK to).
Add the %JAVA_HOME%\bin folder to your PATH (e.g. by replacing the part with C:\Program Files\Java\jdk1.7.0_04). Make sure that you use ; to separate different path components.
Likewise, the M2_HOME variable should be assigned Maven's installation directory, e.g. C:\Program Files\apache-maven-3.0.4 and you should add %M2_HOME%\binto the PATH (the part with C:\Program Files\apache-maven-3.0.4\bin;M2_HOME;%M2% can be removed.
The advantage of adding the environmental variables %JAVA_HOME%\bin and %M2_HOME%\bin on the path rather than the fully qualified path is that it will be easy to update Java and Maven (or to have several versions installed in parallell). All you need to do is to update the environmental variable, and the PATH variable will fallow automatically.
I ran into the same issue as the original poster. I checked, double checked, and triple checked everything to conform to what everyone has (correctly) indicated the setup needs to be. I still got the same error. In the end, I ran SET JAVA_HOME=C:\Program Files\Java\jdk1.7.0_45 from the command line and then ran the mvn command and viola.
So, for what ever reason, pss's suggestion did the trick. Obviously, this doesn't really change what everyone else said, because that's exactly what my environment variables look like...just had to hit the JAVA_HOME from the command line.
Oddness.
I followed all the steps but it was not working for me. But as soon i have set the JAVA_HOME Path, in Command prompt just type:
C:>SET JAVA_HOME=C:\Program Files (x86)\Java\jdk1.8.0_91
It is working fine in fraction of seconds. Thanks Everyone.
I faced the same problem on local installation. I tried out all the suggested methods including the SET method but that didn't work for me. In the end, I had to manually add another environment variable to the system, and then after that
mvn -v
gave the appropriate response:
Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T04:57:37-07:00)

If, like me, you are running mvn -version from the command prompt, and then adding any missing environment variables from the GUI, it is possible that you just have to reload the command prompt after adding the environment variables.
Just exit and run cmd.exe
You need to make a variable of name JAVA_HOME in your Environment and set its value as path to jdk.
Right click on My Computer/ This PC -> Properties
Choose Advance system settings
Open Environment variables
Under System variables click on New... button and give the name
as JAVA_HOME and value as c:/path/to/jdk
Version that I always use. Double click and you get the maven up and running

Yes, Appending that path C:\programfiles\maven\bin to path variable in system variables is enough, it will work. No need to add user variables.
I am trying to install grails in my windows 7, I have installed JDK 1.7.0 and downloaded grails from its site and extracted in path "C:\grails", i have jdk in "C:\Program Files\Java\jdk1.7.0". I have set environment variable JAVA_HOME = "C:\Program Files\Java\jdk1.7.0\bin" and GRAILS_HOME = "C:\grails" and added "%GRAILS_HOME%\bin" and JAVA_HOME to path from advanced settings. But when i try to run "grails -v" or "grails help" i get the error "The system cannot find the path specified.". I even changed my directory to "C:\grails" and ran "grails -v" but it is still giving me the same error.
I dont know what is wrong with it, please help me installing this thing.
Thanks
JAVA_HOME = "C:\Program Files\Java\jdk1.7.0\bin" mustn't include 'bin'
You'll want to verify that Java is working correctly first by entering "java -version" at the command line.
When you say you extracted the zip into "C:\grails" does that directory now just have a single sub directory (i.e. "grails-2.5.0" or whatever version you downloaded), or does it contain a bunch of sub directories (bin, conf, dist, doc. etc)?
If the answer is the former, your GRAILS_HOME should point to "C:\grails\grails-2.5.0" instead of just C:\grails\
