The aemanalyser-maven-plugin is a Maven plugin that checks if all the requirements declarations made in OSGi bundles are satisfied by the capabilities declarations of other bundles included in the Maven project. This plugin ensures that the OSGi bundles are consistent and can be resolved at runtime. The plugin also checks for other issues such as API compatibility, package versioning, and bundle start order.

To enable JSON export on any component after defining a Sling Model, you need to annotate the Sling Model interface with @Exporter annotation. This annotation is part of the Sling Model Exporter framework which allows Sling Models to be exported in JSON format.

Here is the detailed step-by-step explanation:

Define the Sling Model: Define your Sling Model with the necessary annotations and methods. For example:

@Model(adaptables = Resource.class)

public class MyModel {

@Inject

private String title;

public String getTitle() {

return title;

}

}

Annotate with @Exporter: Annotate the Sling Model class with @Exporter to enable JSON export. The @Exporter annotation configures the model to be exported as JSON.

@Model(adaptables = Resource.class)

@Exporter(name = "jackson", extensions = "json")

public class MyModel {

@Inject

private String title;

public String getTitle() {

return title;

}

}

Access the JSON Output: Once annotated, the JSON representation of the model can be accessed through the .model.json extension. For example, if your component is at /content/mysite/en, you can access the JSON output at:

http://localhost:4502/content/mysite/en.model.json

This approach leverages the Sling Model Exporter framework to seamlessly convert Sling Models to JSON format, making it easy to integrate with front-end frameworks and other systems that consume JSON data.

To create Sling Models that can export data in a human-readable yaml format, the following steps are required:

Create Sling models to export as yaml. Sling models are Java classes that can be used to represent resources in AEM. Sling models can use annotations to define how they can be adapted from a resource and how they can export data in different formats. To export data in yaml format, the Sling model class needs to use the @Model annotation with the resourceType parameter set to the resource type of the resource that the model represents. The Sling model class also needs to implement the org.apache.sling.models.annotations.Exporter annotation with the name parameter set to “jackson” and the extensions parameter set to “yaml”. The Sling model class also needs to use the @JsonProperty annotation on the fields or methods that need to be exported in yaml format.

Configure mime type in Apache Sling MIME Type Service. The Apache Sling MIME Type Service is an OSGi service that maps file extensions to MIME types and vice versa. To enable the yaml format for Sling models, the MIME Type Service needs to be configured with a new entry for the yaml extension and its corresponding MIME type, which is “application/x-yaml”. This can be done by creating an OSGi configuration for the org.apache.sling.commons.mime.internal.MimeTypeServiceImpl service and adding the entry “yaml=application/x-yaml” to the mime.types property.

To generate a test coverage report for an AEM project using the latest archetype, the correct plugin to use is the maven-surefire-plugin (Option A). The maven-surefire-plugin is a part of the Maven ecosystem and is widely used to run unit tests within a Maven project. This plugin can be configured to generate detailed test reports, including HTML versions, which can be easily shared with clients.

Here’s how to configure the maven-surefire-plugin to generate test coverage reports:

Add the Plugin to the POM File: Add the maven-surefire-plugin configuration in your pom.xml file:

org.apache.maven.plugins

maven-surefire-plugin

2.22.2

${project.build.directory}/surefire-reports

html

false

Execute the Maven Command: Run the following command to execute the tests and generate the coverage report:

mvn clean test

Locate the Report: The HTML test coverage report will be generated in the target/surefire-reports directory of your project.
