Error not a JRE when running maven install

Translated from jingyan.baidu.com/article/c85b7a6464d8be003bac95fb.html

(Linux I directly follow the second step, error resolution)

When you run Maven install with Eclipse,

[ERROR] Unable to locate the Javac Compiler In:d:\program files\java\jre6\. \lib\tools.jar ensure you be 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.

1. Set in the Eclipse.ini file

   -VM C:\Program Files\java\jdk1.6.0_21\jre\bin\javaw.exe

   Note To set this line before-startup in the Eclipse.ini file

2. window-->preferences-->java-->installed JREs: Set path to the path of the JRE

3. Restart Eclipse
