[MWRAPPER-151] Maven Wrapper not handling usernames with spaces on Windows

**[Jack Green](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=JIRAUSER307283)** opened **[MWRAPPER-151](https://issues.apache.org/jira/browse/MWRAPPER-151?redirect=false)** and commented

When Maven wrapper is run on a username with spaces on Windows, it doesn’t work and an error is produced:

 

```java
'C:\Users\Test' is not recognized as an internal or external command, operable program or batch file.
Cannot start maven from wrapper
```

 

 

Reproducer:
- Have a username with spaces is in it (e.g. `{}Test User Name{`})

- Create Maven wrapper (`{}mvn wrapper:wrapper{`})

- Run the newly created Maven wrapper (`{}mvnw –version{`})

 

I _suspect_ this is being caused by the following pattern:

`Write-Output "MVN_CMD=$MAVEN_HOME/bin/$MVN_CMD"`

 

Where `$MAVEN_HOME` contains spaces and is not being quoted correctly.
