> Hi,
>  
> when executing `{color:#0747a6}{{./mvnw}}{color}` behind a proxy and the proxy authentication does not succeed, {color:#0747a6}{{wget}}{color} will still create an empty file {color:#0747a6}{{.mvn/maven-wrapper.jar}}{color}.
>  
> Subsequent calls to {color:#0747a6}{{./mvnw}}{color} will see the existing (but empty) file and maven-wrapper will not attempt to redownload it. There is no clue what is going wrong, the only message is "Main class not found".
>  
> Suggested fixes:
>  * Check curl/wget return codes and delete the files if they got touched.
>  * Even if curl/wget were not invoked, delete empty files.
