Francois MAROT updated MNG-8315:
--------------------------------
Description:
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: :
{code:java}
"-Dmaven.multiModuleProjectDirectory=o:\"{code}
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:
{code:java}
"-Dmaven.multiModuleProjectDirectory=o:"{code}
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:
{code:java}
if "%MAVEN_PROJECTBASEDIR:~-1%"=="\" set
"MAVEN_PROJECTBASEDIR=%MAVEN_PROJECTBASEDIR%\"{code}
A workaround for users facing the problem is to define MAVEN_BASEDIR to the
drive root with 2 backslash before running Maven:
{code:java}
set MAVEN_BASEDIR=%tempDriveLetter%:\\{code}
