Diego Rivera created MSHADE-244:
-----------------------------------
Summary: Avoid file copy and replacement when source and target
files are the same file
Key: MSHADE-244
URL: https://issues.apache.org/jira/browse/MSHADE-244
Project: Maven Shade Plugin
Issue Type: Bug
Affects Versions: 2.4.3
Reporter: Diego Rivera
Priority: Blocker
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.
