編譯maven時出現編譯錯誤。使用maven編譯時無法找到Javac編譯器 - 無法找到Javac編譯器：
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] Unable to locate the Javac Compiler in:
C:\Program Files\Java\jre1.6.0_05\..\lib\tools.jar
所以我設置了JAVA_HOME環境變量但沒有優勢。該錯誤似乎Maven搜索Java編譯器在JRE路徑中，而不是在JAVA_HOME。
JAVA_HOME是C:\Program Files\Java\jdk1.6.0_05。安裝的JRE是
C:\Program Files\Java\jre1.6.0_05。我
PATH變量是：
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
這裏是我的詳細日誌

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.

如果您對此有任何的想法，讓我知道。
可以包含'mvn --version'的輸出嗎？ –
（你確實在設置'JAVA_HOME'後啓動了一個* new *命令窗口，對嗎？） –
我只是在eclipse中使用maven plugin。 – swemon
