M2Eclipse 编译出现 Unable to locate the Javac Compiler 错误。

创建D:\App\Java\lib目录

将D:\App\Java\jdk1.6.0_21\lib\tools.jar jar 包拷贝到创建的目录，重新运行。

Unable to locate the Javac Compiler in:
C:\Program Files\Java\jre6\..\lib\tools.jar
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
In most cases you can change the location of your Java
installation by setting the JAVA_HOME environment variable.
Both JAVA_HOME and eclipse -vm option are set, it occurred after the m2eclipse installed long time ago. Today it raised suddenly. However the error message may be confused. The tools.jar doesn't locate in C:\Program Files\Java\jre6\..\lib\tools.jar. my JDK directory is liked this:
├─jdk1.6.0_17
│ ├─bin
│ ├─demo
........................................
│ ├─jre
│ │ ├─bin
│ │ │ ├─client
│ │ │ ├─new_plugin
│ │ │ └─server
│ │ └─lib
.........................................
│ ├─lib
.........................................
├─jre6
│ ├─bin
│ │ ├─client
│ │ └─new_plugin
│ └─lib
.........................................
└─lib (doesn't exist)
I create the lib and put tools.jar in that jre6/../lib, it works.
