mvn 打包问题

通过mvn调用ant 的build.xml 文件

Mvn 命令出错，出错信息：

而直接 echo  %Java_Home%

得到：

D:\Java\jdk1.6.0_01

 

再直接mvn –version：

Apache Maven 3.0.4 (r1232337; 2012-01-17 16:44:56+0800)

Maven home: D:\Java\apache-maven-3.0.4

Java version: 1.6.0_01, vendor: Sun Microsystems Inc.

Java home: D:\Java\jdk1.6.0_01\jre

Default locale: zh_CN, platform encoding: GBK

OS name: "windows vista", version: "6.1", arch: "x86", family: "windows"

 

发现 的确 mvn 指向的java home 是D:\Java\jdk1.6.0_01\jre

解决方法：

 

在build.xml 文件中添加

<property name="build.compiler" value="extJavac"/>
