So this is about a versionless dependency of the spotbugs plugin:

<dependency>
  <groupId>com.github.spotbugs</groupId>
  <artifactId>spotbugs</artifactId>
</dependency>

Anyway, I see that something's not right even in 2.14.2 since we're trying to retrieve updates for com.github.spotbugs:spotbugs:jar:[,0]... which will be satisfied by any possible version. But I think that is a separate issue which is probably present in more places. To be investigated.

What result will be if you execute for such project:

mvn spotbugs:check

Error if given pom.xml is called

(If I call spotbugs:check on a project that is a child of this pom.xml, then the check succeeds)

proj1 this pom call spotbugs:check ERROR
proj2 ( proj1) call spotbugs:check OK

The problem is initially with maven versions and does not apply to the call to spotbugs:check (the version to call is determined successfully from dependencyManagement)

I hope the fix is successful (#974)
