Slawomir Jaranowski commented on MWRAPPER-57:
---------------------------------------------
Another proposition MWRAPPER-59 - inline {{MavenWrapperDownloader.java}} into
{{mvnw}} script.
> Make sure that Maven Wrapper created with distribution type set to script
> won't fail on Unix machines

> Key: MWRAPPER-57
> URL: https://issues.apache.org/jira/browse/MWRAPPER-57
> Project: Maven Wrapper
> Issue Type: Improvement
> Components: Maven Wrapper Plugin
> Reporter: Adam Gabrys
> Priority: Minor
>
> When the Maven {{wrapper:wrapper}} goal is executed with the
> {{-Dtype=script}} parameter the {{maven-wrapper.jar}} and
> {{MavenWrapperDownloader.java}} files are not created. The problem is that
> the {{mvnw.cmd}} script guarantees that the Maven distribution will be
> downloaded. However, the {{mvnw}} script fails when the {{curl}} and {{wget}}
> binaries are not installed. It may cause potential issues like "works on my
> PC, but fails on the {{CI}} system". The documentation doesn't Inform the
> users about that fact.
> I see a few possibilities to handle it:
> # remove the {{script}} option, then the people use {{bin}} or {{source}}.
> The {{source}} option generates the required {{MavenWrapperDownloader.java}}
> file
> # extend the {{script}} documentation with a warning that it may fail
> # generate different scripts depending on the chosen option - when {{script}}
> is not
