描述

WriteLinesToFile appends by default unless you specify Overwrite. This is highly non-intuitive and probably almost never what the user intends.

Since we can't change the behavior, I propose to introduce a new optional parameter Append, that defaults to false, and if it's not specified and Overwrite is not specified, warn about it (that you should specify one or the other).

Not sure if a warning or a message, perhaps build check?

研究方向
Examine the existing WriteLinesToFile task implementation in the MSBuild source code (likely in the 'src/Tasks' directory). Understand how task parameters are defined and how warnings are emitted. Propose adding an 'Append' parameter and implement a warning when neither 'Append' nor 'Overwrite' is set. Consider using the existing warning infrastructure such as the WarningTask or TaskLoggingHelper.
