[PR] [MWRAPPER-150] - Fails to validate checksums on MacOS Sequoia [maven-wrapper]

["jon-signal (via GitHub)" <gi...@apache.org>]

jon-signal opened a new pull request, #155:

   The version of `sha256sum` that ships with macOS Sequoia appears to have a bug where it does not read from stdin by default, even though its `man` page says, in part (emphasis added):
   
   > In all cases, each file listed on the command line is processed separately.  **If no files are listed on the command line**, or a file name is given as -, input is taken from stdin instead.
   
   …but invoking `sha256` as it appears in the `mvnw` script does not work as expected:
   
   ```sh
   ❯ echo '3d8f20ce6103913be8b52aef6d994e0c54705fb527324ceb9b835b338739c7a8  /Users/jon/REDACTED/.mvn/wrapper/maven-wrapper.jar' | sha256sum -c
   usage: sha256sum [-bctwz] [files ...]
   ```
   
   …which in turns to a non-successful exit code, which in turn leads to a (rather alarming!) warning about a mismatched checksums and possible compromise.
   
   Adding a `-` explicitly calls for `sha256sum` to read from stdin.
