ant 出现 Unable to find a javac compiler

在ant打包时报错：

解决com.sun.tools.javac.Main is not on the classpath的问题

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"

遇到这种情况时直接将C:\Program Files\Java\jdk1.6.0_17\lib中的tools.lib拷贝到C:\ProgramFiles\Java\jre6\lib中即可。
