Interface ComponentSelectionRules

public interface ComponentSelectionRules

Represents a container for component selection rules. Rules can be applied as part of the resolutionStrategy of a configuration and individual components can be explicitly accepted or rejected by rule. Components that are neither accepted or rejected will be subject to the default version matching strategies.

     configurations {
         conf {
             resolutionStrategy {
                 componentSelection {
                     all { ComponentSelection selection ->
                         if (selection.candidate.module == 'someModule' && selection.candidate.version == '1.1') {
                             selection.reject("bad version '1.1' for 'someModule'")
                         }
                     }
                     all { ComponentSelection selection ->
                         if (selection.candidate.module == 'someModule' && selection.getDescriptor(IvyModuleDescriptor)?.branch == 'testing') {
                             if (selection.metadata == null || selection.metadata.status != 'milestone') {
                                 selection.reject("only use milestones for someModule:testing")
                             }
                         }

Method Detail

all

ComponentSelectionRules all(Action<? super ComponentSelection> selectionAction)

Adds a simple component selection rule that will apply to all resolved components. Each rule will receive a ComponentSelection object as an argument.

Parameters:

selectionAction - the Action that implements a rule to be applied

Returns:

this

all

ComponentSelectionRules all(@DelegatesTo(ComponentSelection.class)
                            Closure<?> closure)

Adds a component selection rule that will apply to all resolved components. Each rule will receive a ComponentSelection object as an argument.

Parameters:

closure - the Closure that implements a rule to be applied

Returns:

this

all

ComponentSelectionRules all(java.lang.Object ruleSource)

Adds a rule-source backed component selection rule that will apply to all resolved components. The ruleSource provides the rule as exactly one rule method annotated with Mutate. This rule method:

• must return void.
• must have ComponentSelection as its parameter.

Parameters:

ruleSource - an instance providing a rule implementation

Returns:

this

withModule

ComponentSelectionRules withModule(java.lang.Object id,
                                   Action<? super ComponentSelection> selectionAction)

Adds a component selection rule that will apply to the specified module. Each rule will receive a ComponentSelection object as an argument.

Parameters:

id - the module to apply this rule to in "group:module" format or as a ModuleIdentifier

selectionAction - the Action that implements a rule to be applied

Returns:

this

withModule

ComponentSelectionRules withModule(java.lang.Object id,
                                   @DelegatesTo(ComponentSelection.class)
                                   Closure<?> closure)

Adds a component selection rule that will apply to the specified module. Each rule will receive a ComponentSelection object as an argument.

Parameters:

id - the module to apply this rule to in "group:module" format or as a ModuleIdentifier

closure - the Closure that implements a rule to be applied

Returns:

this

withModule

ComponentSelectionRules withModule(java.lang.Object id,
                                   java.lang.Object ruleSource)

Adds a rule-source backed component selection rule that will apply to the specified module. The ruleSource provides the rule as exactly one rule method annotated with Mutate. This rule method:

• must return void.
• must have ComponentSelection as its parameter.

Parameters:

id - the module to apply this rule to in "group:module" format or as a ModuleIdentifier

ruleSource - an instance providing a rule implementation

Returns:

this
