Example 1 with ComponentConfiguration

use of com.amazon.aws.iot.greengrass.component.common.ComponentConfiguration in project aws-greengrass-nucleus by aws-greengrass.

the class KernelConfigResolverTest method getComponent.

private ComponentRecipe getComponent(String componentName, String componentVersion, Map<String, DependencyProperties> dependencies, JsonNode defaultConfiguration, String jsonPointerStr, String crossComponentName, String crossComponentJsonPointerStr) {
    ComponentConfiguration componentConfiguration = defaultConfiguration == null ? null : ComponentConfiguration.builder().defaultConfiguration(defaultConfiguration).build();
