Description

Assume a project without the maven wrapper present and the ~/.m2/wrapper/dists is empty.

In the project install the 3.1.1 wrapper version with a different REPO url

$ MVNW_REPOURL=https://repo1.maven.org/maven2 mvn org.apache.maven.plugins:maven-wrapper-plugin:3.1.1:wrapper 

The config now contains

$ fgrep Url .mvn/wrapper/maven-wrapper.properties 
distributionUrl=https://repo1.maven.org/maven2/org/apache/maven/apache-maven/3.9.0/apache-maven-3.9.0-bin.zip
wrapperUrl=https://repo1.maven.org/maven2/org/apache/maven/wrapper/maven-wrapper/3.1.1/maven-wrapper-3.1.1.jar 

Now try to self upgrade

$ MVNW_REPOURL=https://repo1.maven.org/maven2 ./mvnw wrapper:wrapper   
Exception in thread "main" java.io.FileNotFoundException: https://repo1.maven.org/org/apache/maven/apache-maven/3.9.0/apache-maven-3.9.0-bin.zip     at 

Important to note here

1. The URL it is trying to download from is the specified hostname but without the specified path on that host.
2. The distributionUrl specified in  .mvn/wrapper/maven-wrapper.properties is the valid URL that yields the correct file.
