遇到这样的错误:
Eclipse is running in a JRE, but a JDK is required
Some Maven plugins may not work when importing projects or updating source folders.
可以用一下方法解决
在eclipse.ini中添加VM启动参数，制定eclipse启动使用的vm，修改后的文件内容如下
org.eclipse.platform
--launcher.XXMaxPermSize
256M
-vm
C:\Program Files\Java\jdk1.5.0_12\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
-showsplash
问题2 :
org.apache.maven.plugin.CompilationFailureException: Compilation failure
Unable to locate the Javac Compiler in:
C:/Program Files/Java/jre1.5.0_07/../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.
方法：
Windows->preferences->java->installed jREs ->中加上tools.jar
