These are used to indicate a target element in the out going message assembly, where an acquired value should overwrite the existing value (in the case where the element already exists in the tree).

这些表达式用于指示输出消息组件中的目标元素，其中获取的元素应该重写现有值(假如树中已经存在元素)。

Since the original task has the -de overwrite option, even though the destination file already exists from the previous transfer, the new transfer will complete successfully.

由于原始任务拥有 -de 覆盖选项，即使目标文件自上次传输后已经存在，新传输任务仍将成功执行。

Another important point here is the Overwrite property which is set to true: As a consequence, if the EAR file to be generated already exists, it will be overwritten.

另外一点比较重要需要指出的是Overwrite属性被设置为真：结果，如果一个生成的EAR文件已经存在的话，那么它将会被覆盖掉。
