---------------------------------
Summary: Maven 4 prompter broken
Key: MNG-8530
URL: https://issues.apache.org/jira/browse/MNG-8530
Project: Maven
Issue Type: Bug
Affects Versions: 4.0.0-rc-2
Reporter: Stefan Oehme
The [new
prompter|https://github.com/apache/maven/blob/master/impl/maven-core/src/main/java/org/apache/maven/internal/impl/DefaultPrompter.java#L50]
implementation reflectively calls the old one and always uses the same method
no matter what overload was called:
{code:java}
clazz.getMethod("prompt", String.class, List.class, String.class); {code}
This is incorrect and leads to nullpointers when calling the new prompter with
just a `message`, but no `possibleValues`.
The new prompter should delegate to the correct overload of the old prompter
instead of redirecting all calls to the same method. Also, the nullability
annnotations are wrong. The message is never nullable. And if an overload with
`possibleValues` is called, they must not be null.
