Torben Knerr commented on MNG-3890:
-----------------------------------
Same problem here. Want to set {{javax.validation:validation-api}} to
{{provided}} but it still ends up being packaged in the .war file, because it
turns out to be a transitive dependency of {{gwt-user}} as well.
Workaround: set it to {{provided}} scope AND {{excludes}} it from the other
artifact:
{code}
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>${gwtVersion}</version>
<exclusions>
<exclusion>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</exclusion>
</exclusions>
</dependency>
...
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<scope>provided</scope>
</dependency>
...
{code}
> Transitive dependencies override explicitly set scope.

> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Dependencies
> Affects Versions: 2.0.9, 2.1.0-M1, 3.0-alpha-1

> Transitive dependencies override explicitly set scope.
> E.g. a project A depends on "Hibernate" with default scope and a project B
> depends on project A as well as on "Hibernate" for which it sets the scope
> explicitly to "provided". Further an EAR project C depends on project B (see
> the attached testcase).
> Now I would expect that C does not contain any jars for Hibernate and its
> dependencies since B explicitly set the scope to "provided". Sadly this is
> not the case and C contains all hibernate jars. The only way around this I
> have found is setting the scope to "provided" for Hibernate in A as well -
> which is just a crude hack that produces other issues.
> IMHO this is a bug because Maven should respect the overridden dependency
> scope since the current way forces me to set the scope to provided in A which
> is just wrong.
> Please try to get this fixed for 2.10 or 2.1 since it's a real pita atm.
