问题
I set my JAVA_HOME variable to point to the jdk and I added %JAVA_HOME%\bin to the Path variable. However, my ant script is not able to find the jdk. It's looking into the wrong folder for Java compiler. here's the error I'm getting.
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to C:\Program Files\Java\jre6
I set my JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0
What am I doing wrong? Please help!
回答1:
If your Java installation directory has a space in its path name, you should use the shortened path name (e.g. C:\Progra~1\Java\jre6) in the environment variable instead.
- Progra~1 = 'Program Files'
- Progra~2 = 'Program Files(x86)'

Try setting it to
JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0\jre

When you want to use JAVA_HOME in your path variable it is recommended to use "%JAVA_HOME%\bin" instead of %JAVA_HOME%\bin .
