[MWRAPPER-82] mvnw.cmd fails when run from a parent directory.

**[Christopher Holt](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=JIRAUSER297975)** opened **[MWRAPPER-82](https://issues.apache.org/jira/browse/MWRAPPER-82?redirect=false)** and commented

running "c:\project\module\mvn.cmd" from "c:\project" will fail like this:

 
The system cannot find the file C:\project\.mvn\wrapper\maven-wrapper.properties
 

It should look in c:\project\module, not c:\project for the .mvn folder. 

This works fine with the mvnw sh script under linux.

Under liniux, the sh script starts from "dirname $0" looking for .mvn.  The cmd script starts from "%CD%".  wrapping this line:

 
set EXEC_DIR=%CD%
 
with pushd/popd calls fixes the problem.
 
i.e:
 
pushd %~dp0
set EXEC_DIR=%CD%
popd
 
Since this script is created and added to version control for the project, the workaround is to simply fix the generated scipt.
