maven错误处理

错误信息见 附录。

如何定位：

1、开启 -X模式，打印详细日志。进入到子的module，执行mvn eclipse:eclipse-DskipTests -X

2、从-X的日志中看到如下信息，从调用堆栈的函数，如下是三个参数，对第二个参数做getCanonicalPath的时候报错。中间有个G:无法解析！

[DEBUG] Making relative and fixing separator: { G:\project\apache-lens-2.6.1\lens-dist, G:\project\apache-lens-2.6.1\lens-dist\target\classes\G:\project\apache-lens-2.6.1\lens-dist\target\debian\control, false }

3、如何修改，在父工程中做如下修改：

 
    ${src.dir}
   
     
        ${basedir}/src/deb/control
       
       
        ../debian/control
        true
     

和原来的实现效果一直。targetPath一般不建议用绝对路径，这里也提到了（https://issues.apache.org/jira/browse/MECLIPSE-269）。

测试通过。另外说明下 File类的getCanonicalPath()方法，“返回的是规范化的绝对路径，相当于将getAbsolutePath()中的“.”和“..”解析成对应的正确的路径”。所以修改 ../debian/control是可以返回正确的绝对路径的。
