编译maven时出现编译错误。使用maven编译时无法找到Javac编译器 - 无法找到Javac编译器：
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] Unable to locate the Javac Compiler in:
C:\Program Files\Java\jre1.6.0_05\..\lib\tools.jar
所以我设置了JAVA_HOME环境变量但没有优势。该错误似乎Maven搜索Java编译器在JRE路径中，而不是在JAVA_HOME。
JAVA_HOME是C:\Program Files\Java\jdk1.6.0_05。安装的JRE是
C:\Program Files\Java\jre1.6.0_05。我
PATH变量是：
C:\Program Files\PC Connectivity Solution\;D:\alfrescoplatform\ImageMagick;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\system32\Wbem;C:\Program Files\ImageMagick-6.7.3-Q16;C:\Program Files\Java\jdk1.6.0_05\bin
这里是我的详细日志

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.

如果您对此有任何的想法，让我知道。
可以包含'mvn --version'的输出吗？ –
（你确实在设置'JAVA_HOME'后启动了一个* new *命令窗口，对吗？） –
我只是在eclipse中使用maven plugin。 – swemon
