Pros of Jetty

• Lightweight and highly customizable servlet container
• Excellent performance and scalability for web applications
• Extensive documentation and active community support

Cons of Jetty

• Less feature-rich compared to Nexus Public for repository management
• Steeper learning curve for beginners in web server configuration
• Limited built-in security features compared to Nexus Public

Code Comparison

Jetty (Server Configuration):

Server server = new Server(8080);
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
server.setHandler(context);
context.addServlet(new ServletHolder(new HelloServlet()), "/*");

Nexus Public (Repository Configuration):

Repository repository = new Repository();
repository.setName("maven-central");
repository.setFormat("maven2");
repository.setType(RepositoryType.PROXY);
repository.setUrl("https://repo1.maven.org/maven2/");
repositoryManager.create(repository);

The code snippets demonstrate the different focus areas of the two projects. Jetty's code shows server and servlet configuration, while Nexus Public's code illustrates repository management setup.

Pros of Spring Boot

• Extensive documentation and large community support
• Simplified configuration with auto-configuration feature
• Wide range of starter dependencies for easy project setup

Cons of Spring Boot

• Steeper learning curve for beginners
• Can be overkill for small, simple applications
• Potential for "magic" behavior due to auto-configuration

Code Comparison

Spring Boot:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Nexus Public:

public class NexusApplication {
    public static void main(String[] args) throws Exception {
        new Bootstrap().run(args);
    }
}

Spring Boot focuses on simplifying the setup process with annotations and auto-configuration, while Nexus Public requires more manual configuration. Spring Boot's approach leads to less boilerplate code but may obscure some underlying processes. Nexus Public offers more explicit control but requires more setup code.

Both projects serve different purposes: Spring Boot is a framework for building stand-alone, production-grade Spring-based applications, while Nexus Public is a repository manager. The comparison highlights their different approaches to application structure and initialization.

Pros of Gradle

• More flexible and extensible build system with powerful DSL
• Faster build times due to incremental builds and build cache
• Larger ecosystem with extensive plugin support

Cons of Gradle

• Steeper learning curve, especially for complex builds
• Can be memory-intensive for large projects
• Slower initial project setup compared to Maven-based systems

Code Comparison

Nexus (Java):

@Named
public class NexusOrientation {
    @Inject
    public NexusOrientation(final BundleContext bundleContext) {
        // Initialization code
    }
}

Gradle (Groovy DSL):

plugins {
    id 'java'
}

dependencies {
    implementation 'org.example:library:1.0'
}

Gradle focuses on build automation and dependency management, while Nexus is primarily a repository manager. Gradle offers more flexibility in defining build processes, whereas Nexus excels in artifact storage and distribution. Gradle's syntax is more concise and expressive, allowing for easier customization of build scripts. However, Nexus provides a centralized solution for managing dependencies across multiple projects and teams. Both tools serve different purposes in the software development lifecycle and can be used complementarily in many environments.

Pros of Maven

• Widely adopted and well-established build automation tool
• Extensive plugin ecosystem for various tasks and integrations
• Declarative dependency management with transitive dependencies

Cons of Maven

• Steeper learning curve for complex project configurations
• XML-based configuration can be verbose and less flexible
• Limited support for dynamic builds compared to newer tools

Code Comparison

Maven (pom.xml):

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.example</groupId>
  <artifactId>my-app</artifactId>
  <version>1.0-SNAPSHOT</version>
</project>

Nexus (example configuration):

{
  "name": "my-repository",
  "type": "maven2-hosted",
  "online": true,
  "storage": {
    "blobStoreName": "default",
    "strictContentTypeValidation": true
  }
}

Maven focuses on project build configuration, while Nexus-public is centered around repository management. Maven's XML-based configuration defines project structure and dependencies, whereas Nexus uses JSON for repository setup. Both tools serve different purposes in the Java ecosystem, with Maven handling build processes and Nexus managing artifact repositories.
