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

 

在重装了JDk之后,有可能会使Eclipse在编译工程的时候出现如下错误:

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/jre1.5.0_11"


遇到这种情况时直接将C:/Program Files/Java/jdk1.5.0_11/lib中的tools.lib拷贝到C:/Program Files/Java/jre1.5.0_11/lib中即可。
如果还是不行,那请配置一下JDK的环境变量,并关闭IDE然后重新打开。
