Why does ANT tell me that JAVA_HOME is wrong when it is not?

Question

I get the error:

C:\\dev\\ws\\springapp\\build.xml:81: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not

Answer 1

had the same problem;

c:\jb\src\build.xml:191: Unable to find a javac compiler;
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\jre7"

Total time: 0 seconds

c:\jb\src>echo %JAVA_HOME%
c:\Program Files\Java\jdk1.7.0_13

solution:

path = c:\ant\bin\;%PATH%
path = c:\Program Files\Java\jdk1.7.0_17\bin;%PATH%
set "JAVA_HOME=c:\Program Files\Java\jdk1.7.0_13"

I guess the jdk path instruction alone would do it but I'm to lazy to figure it out above solution is bullet proof. :-)
