----------------------------------------
Maybe some code helps demonstrating the issue behind this. In
[MavenRepositorySystemUtils|https://git-wip-us.apache.org/repos/asf?p=maven.git;a=blob;f=maven-aether-provider/src/main/java/org/apache/maven/repository/internal/MavenRepositorySystemUtils.java;h=3a98b2acc53b828479057814fb0ca4f2f0b30e03;hb=HEAD]
you have
{code}
101 DependencySelector depFilter =
102 new AndDependencySelector( new ScopeDependencySelector(
"test", "provided" ),
103 new OptionalDependencySelector(),
new ExclusionDependencySelector() );
104 session.setDependencySelector( depFilter );
{code}
The 'ScopeDependencySelector' is setup to exclude transitive dependencies with
scope "test" or "provided". The fix to Aether will stop Aether from returning
transitive 'test' scope dependencies. The 'OptionalDependencySelector' is setup
to exclude transitive dependencies with 'optional' set to 'true'. The fix to
Aether will stop Aether from returning optional transitive dependencies.
> The 'optional' flag of a dependency should be manageable.
