Michael Osipov updated MNG-8315:
--------------------------------
Summary: Failure of mvn.cmd if a .mvn directory is located at drive root
(was: Failure of mvn.cmd if a .mvn folder is located at drive root)
> Failure of mvn.cmd if a .mvn directory is located at drive root
> ---------------------------------------------------------------
>
> Key: MNG-8315
> URL: https://issues.apache.org/jira/browse/MNG-8315
> Project: Maven
> Issue Type: Bug
> Components: Command Line
> Affects Versions: 3.9.9
> Environment: Windows 10
> Reporter: Francois MAROT
> Priority: Minor
> Labels: easyfix
>
> When .mvn is located on filesystem root, on Windows, the command line created
> (in mvn.cmd) to run java fails.
> This is because the part concerning multiModuleProjectDirectory ends with a
> slash before the double quote which certainly means escaping and it messes
> the whole command. Example for drive o: :
> "-Dmaven.multiModuleProjectDirectory=o:\"
> In this case, java.exe displays its usage help as it thinks the command is
> wrong.
> The workaround is to add an additional escaping backslash:
> "-Dmaven.multiModuleProjectDirectory=o:"
> Note: this only happens in case there is a .mvn at root.
>
> This simple line added just before calling "%JAVACMD%" seems to do the job:
> if "{_}%MAVEN_PROJECTBASEDIR:~-1%"=="{_}\" set
> "MAVEN_PROJECTBASEDIR=%MAVEN_PROJECTBASEDIR%\"
>
>
