Review Comment:
The docs don't provide this constraint about `distributionUrl`; and when the
`distributionUrl` is a releative path, we don't check for the correct
repository style url. As an user I was not aware the `distributionUrl` must be
in format of repository layout. Since the maven-wrapper is a tool, I would
recommend to warn the user of improper use, but not force the user for this
format.
Otherwise I think we should change the settings from `distibutionUrl` in
`distributionVersion` and use `MVNW_REPOURL` as `mvnwRepoUrl` because users
are forced to use repositories. And we can easily guess the url with the
version number, because `packaging`, `groupId` and `artifactId` are fix.

> MVNW_REPOURL improperly formed distributionUrl
> ----------------------------------------------
>
> Key: MWRAPPER-68
> URL: https://issues.apache.org/jira/browse/MWRAPPER-68
> Project: Maven Wrapper
> Issue Type: Bug
> Components: Maven Wrapper Jar
> Affects Versions: 3.1.1
> Reporter: HumanFund
> Priority: Major
>
> In Maven Wrapper v3.1.1, Installer::createDist(), file
> maven-wrapper/src/main/java/org/apache/maven/wrapper/Installer.java, was
> updated on line 74 to be:
> distributionUrl = new URI( mvnwRepoUrl ).resolve( "/" ).resolve( mvnPath );
> The above update is causing the distributionUrl to be improperly formed based
> on the MVNW_REPOURL environment variable and the mvnPath which is extracted
> from the distributionUrl in maven-wrapper.properties, specifically the
> substring starting with "org/apache/maven".
> The update was introduced in the following commit:
> [https://github.com/apache/maven-wrapper/commit/22a3268def96e5e648aa97a49d9e146e529b7c87#diff-193f3775e6efb0b6ed01219b21272f9eb3861965ce3af3586a0ce8eb153359c0]
> An example of the results are shown below. Note the "Downloading" URI does
> not include the entire repo url, only the scheme, host, and port, then the
> maven path is appended.
> The repo url is getting truncated by the call to resolve( "/" ) on line 74.
> I do not currently see a purpose for having this call in place. I made the
> following update to line 74 and it works fine:
> distributionUrl = new URI( mvnwRepoUrl ).resolve( mvnPath );
> Note that in Maven Wrapper v3.1.0, the distributionUrl was formed simply by
> appending the maven path to the MVNW_REPOURL:
> distributionUrl = new URI( mvnwRepoUrl + "/" + mvnPath );
> Example output demonstrating issue:
> [exec] [INFO] Apache Maven Wrapper 3.1.1
> [exec] [INFO] Detected MVNW_REPOURL environment variable
> [http://localhost:8081/repository/repo-maven-apache-org-maven2/]
