             Summary: Windows mvnw.cmd from root directory of drive fails with java usage display
                 Key: MWRAPPER-72
                 URL: https://issues.apache.org/jira/browse/MWRAPPER-72
             Project: Maven Wrapper
          Issue Type: Bug
          Components: Maven Wrapper Scripts
    Affects Versions: 0.5.6
         Environment: Windows 10
            Reporter: Clifford W Johnson
         Attachments: mvnw-cmd_failure.txt

Attempting to use {{.\mvnw.cmd}} when the project root is at the root of a Windows drive (as would happen if {{subst Z: <projectDir>}} is used) results in the script displaying the `java` usage information and not performing the expected Maven operation. It seems that `java` has an issue in parsing the command line argument {{{}"-Dmaven.multiModuleProjectDirectory=Z:\"{}}}.

My local work-around was to append a dot/period ({{{}.{}}}) to the {{EXEC_DIR}} if \{EXEC_DIR}} ends with {{{}:\{}}}.
