-----------------------------------
Summary: Failure of mvn.cmd if a .mvn folder 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
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%\"
