>             Project: Maven Shade Plugin
>          Issue Type: Bug
>    Affects Versions: 2.4.3

> When Shade::replaceFile() is invoked, and the source and target are the same, no work should be performed since this can result in an attempt at copying the same file upon itself, and the target will end up as a 0-byte file.
> Instead, the proposed patch (attached) adds a check to perform a best-attempt intercept of that condition and avoid any unnecessary work.
