-----------------------------------------------------------------
There seems to be a difference between soft and hard requirements which is not
really documented. Soft requirements (aka recommended versions) have to be
given with an exact version match, while hard requirements require resolving
(i.e. checking against metadata/repo whether they exists). Which means that a
dependency on version {{[1]}} is valid if the version {{1.0}} exists, on the
other hand the soft requirement {{1}} is invalid here.

> For dependencies having e.g. version {{[1.0]}} the
> DefaultVersionRangeResolver still tries to resolve versions although only a
> single version (namely 1.0) is valid here according to
> https://maven.apache.org/pom.html#Dependency_Version_Requirement_Specification.
>
> This leads in the worst case to long-running calls against a remote
> repository for no reason.
> There should be a shortcut in
> https://github.com/apache/maven/blob/3f90e7028e0338c110aea267b44362653d55273a/maven-resolver-provider/src/main/java/org/apache/maven/repository/internal/DefaultVersionRangeResolver.java#L108
> when the range has the same upper and lower bound.
