org.eclipse.aether.internal.impl.scope.ManagedScopeSelector

public final class ManagedScopeSelector
extends ConflictResolver.ScopeSelector

A scope selector for use with ConflictResolver that supports the scopes from ScopeManager. In general, this selector picks the widest scope present among conflicting dependencies where e.g. "compile" is wider than "runtime" which is wider than "test". If however a direct dependency is involved, its scope is selected.

This class also "bridges" between DependencyScope and Resolver that uses plain string labels for scopes.

selectScope

public void selectScope(ConflictResolver.ConflictContext context)

Description copied from class: ConflictResolver.ScopeSelector

Determines the effective scope of the dependency given by ConflictResolver.ConflictContext.getWinner(). Implementations will usually iterate ConflictResolver.ConflictContext.getItems(), inspect ConflictResolver.ConflictItem.getScopes() and eventually call ConflictResolver.ConflictContext.setScope(String) to deliver the effective scope.

Specified by:

selectScope in class ConflictResolver.ScopeSelector

Parameters:

context - The conflict context, must not be null.

chooseEffectiveScope

public String chooseEffectiveScope(Set<String> scopes)

Visible for testing. It chooses "widest" scope out of provided ones, unless system scope is present, in which case system scope is selected.
