问题
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?
回答1:
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.
