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")
                        }
                    }
                }
