Inspect Gradle

Try override classpath?

// org.gradle.api.plugins.JavaBasePlugin#defineConfigurationsForSourceSet:324
sourceSet.setRuntimeClasspath(sourceSet.getOutput().plus(runtimeClasspathConfiguration));

Resolve project dependency

// org.gradle.api.internal.artifacts.dependencies.DefaultProjectDependency#resolve(org.gradle.api.internal.artifacts.CachingDependencyResolveContext)
public void resolve(org.gradle.api.internal.artifacts.CachingDependencyResolveContext context) {
    boolean transitive = isTransitive() && context.isTransitive();
    if (transitive) {
        Configuration projectConfiguration = findProjectConfiguration();
        for (Dependency dependency : projectConfiguration.getAllDependencies()) {
            context.add(dependency);
        }
        for (DependencyConstraint dependencyConstraint : projectConfiguration.getAllDependencyConstraints()) {
            context.add(dependencyConstraint);
        }
    }
}

What's the meaning of default configutation in gradle?

// org.gradle.api.plugins.JavaPlugin#apply:264
// Set the 'java' component as the project's default.
Configuration defaultConfiguration = project.getConfigurations().getByName(Dependency.DEFAULT_CONFIGURATION);
defaultConfiguration.extendsFrom(javaComponent.getMainFeature().getRuntimeElementsConfiguration());
((SoftwareComponentContainerInternal) project.getComponents()).getMainComponent().convention(javaComponent);

what is the difference between variant and configuration in gradle?
