Plugin for dependency shortnames

I’m trying to write a plugin where instead of using long GAV, I can simply write the artifact, or some other short name I’ve defined. so instead of

dependencies {
    implementation("org.immutables:value")
    implementation("org.immutables:builder")
    implementation("org.springframework.boot:spring-boot-starter-logging")
}

I could write

dependencies {
    implementation("immutables")
    implementation("logging")
}

So far though all I get is

Supplied String module notation 'immutables' is invalid. Example notations: 'org.gradle:gradle-core:2.2', 'org.mockito:mockito-core:1.9.5:javadoc'.

I’ve tried variations on, but no luck

        conf.getResolutionStrategy().dependencySubstitution( ds -> {
                ds.all( dep -> {
                    ComponentSelector requested = dep.getRequested();
                    if ( requested instanceof ModuleComponentSelector && "immutables".equals( requested.getDisplayName() ) ) {
                        dep.useTarget( "org.immutables:value" );
                    }
                } );
            } );
            conf.withDependencies( ds -> {
                log.info( "ds: {}", ds );
                HashMap<String, String> map = new HashMap<>();
                map.put( "module", "immutables" );
                map.put( "group", "immutables" );
                conf.exclude( map );
                conf.getIncoming().beforeResolve( rd -> {
                    conf.getResolutionStrategy().eachDependency( drd -> {
                        log.info( "drd: {}", drd.getRequested() );
                        ModuleVersionSelector requested = drd.getRequested();
                        requested.getName();
                    } );
                } );
            } );
        } );
