关于build tool的构想 从Ant说起[7]

java代码

class FinallyCommand implements Command{

private final Command c;

private final Command c;

public Object execute（CommandContext ctxt）{

try{

return cexecute（ctxt）;

}

finally{

cexecute（ctxt）;

}

}

FinallyCommand （Command c Command ）{

thisc = c;

thisc = c;

}

}

前面的顺序执行我们是直接扔掉了前一个command的返回值但是有些时候我们也许希望根据第一个command的返回值来决定下一步的走向为此仿照CommandRecovery接口定义CommandBinder接口
