Top 7 Best Java Build Tools

Cutting down workflows is the name of the game in the world of custom software development. Build tools are great for B2B companies in this case since they handle the process of creating, compiling, and managing code. Yet, it’s no easy task to find a match between the features of tools and the particular demands of a project.

Nonetheless, streamlining workflows during development heavily relies on Java build tools - being aware of what they can do and how they can be integrated will set you up for success. By automating the Java application creation process through source code, managing dependencies, and handling bytecode, developers can reduce the likelihood of errors in addition to labour. 

This mechanized coding process also lets developers create unit and integration tests, which expands code coverage analysis. Additionally, it aids in packaging and distributing Java applications, thereby streamlining the software deployment process as a whole. 

Java Build Tools Explained

A build tool is a utility that operates through command-line instructions while automating the process of building applications systematically. Within the Java context, these tools turn code files into bytecode and then package them into executable files or resource libraries.

Having build tools simplifies the process of managing dependencies for enterprises undergoing Java development. By automating tasks, these tools reduce the chances of errors. This, in turn, creates space for the implementation of testing protocols before the deployment of the actual product. The reduction in potential complications augments the likelihood of the final product meeting the criteria set by the client or end-user, thereby fostering confidence in the development team.

What to Look For When Choosing a Tool

When you’re looking for a Java build tool, there are several factors to consider. Personal preference is of course important, but it's best to focus on the complexity of the project, community support and adoption, integration with other tools, and even consider the learning curve for Java developers.

For smaller-volume projects with simple requirements, lightweight tools like Apache Ant can be helpful. However, multiple-module projects that you want to scale up or down include more dependencies and customization needs that require tools with more advanced features. So to put it simply; look for a build tool that offers extensibility and customization with additional plugin features that allow for further customization to meet the specific needs of a project.

Always do your research beforehand, especially when it comes to the scope of the project and how libraries will contribute to performance, structure, or scalability. General libraries, like Boost, STL, or Qt, take more time to research, especially if you need a highly specific function. You’re more likely to find these types of features in libraries meant for particular purposes, such as logging, HTTP, MXL, and connection pools.

A mark of a good tool is best seen in its integration with other tools and the control system version. Through the continual integration of modern Java build tools, there are standard practices that can enhance the development, testing, and deployment of an application, ensuring that any code changes are rapidly delivered and integrated smoothly.

The learning curve for Java can be steep, so always look at starting with tools that are beginner-friendly, like Apache Ant. It will help you, as a developer, gain a practical understanding of the working schematics, while a tool like Maven requires more experience. 

After mastering the basics of Java, make a list of steps for completing just one simple project. Create a map or list that will help you visualize the process. Each step will demand a varying amount of research, so think of a way to keep track of resources and tips. Find online forums with members who have experience and expertise with Java.

Top 7 Java Build Tools

  1. Gradle: Gradle stands as a widely embraced build tool that uses a Groovy-based domain-specific language (DSL) for scripting. Its flexibility is a big draw, and it makes it useful during the construction of diverse software projects.

  2. Apache Maven: Maven, another popular build tool, places a strong emphasis on convention rather than configuration. With an XML-based configuration file, it manages project dependencies and construction processes.

  3. Apache Ant: Despite its age, Apache Ant is still widely utilized as a build tool. It also uses an XML-based configuration file and is super customizable which are both key features that persist in its popularity.

  4. Bazel: Bazel is meant for expansive, multi-language ventures, and is as a purpose-built build tool that’s highly scalable. 

  5. SBT: Engineered explicitly for Scala projects, SBT is a dedicated build tool. The utility relies on a Scala-based DSL for scripting, and its configurability sets it apart.

  6. Dragonboat: Dragonboat is a high-performance multi-group Raft library in Go. With its feature-complete implementation of the Raft consensus algorithm, it has a strong foundation for constructing distributed systems that demand consistency.

  7. Go-Zero: Go-Zero offers a web and RPC framework designed for crafting high-performance and resilient services. It’s a comprehensive solution that encompasses a productivity-enhancing code generation tool named goctl, which elevates its efficiency.

Tool Comparison

The general features and use cases of these tools are something developers should absolutely be aware of. We’ll use Gradle as a point of reference, this is a brief look at how they compare and contrast:

Gradle vs. Apache Maven:

  • Gradle uses a Groovy-based DSL for scripting, while Maven relies on XML configuration.

  • Gradle's flexibility is good for diverse projects, whereas Maven's emphasis on convention specifically simplifies setup.

  • Gradle's learning curve might be steeper because of its scripting language, while Maven's XML configuration is a bit more approachable.

Gradle vs. Apache Ant:

  • Both Gradle and Ant use XML-based configuration, but Gradle's DSL provides more expressiveness.

  • Gradle's adaptability suits varied projects, whereas Ant's customization options are key to its popularity.

  • Gradle often requires less manual XML coding than Ant.

Gradle vs. Bazel:

  • Gradle is versatile and Groovy-based, while Bazel excels in scalability for large, multi-language projects.

  • Gradle's syntax might be more user-friendly for anyone accustomed to scripting languages.

  • Bazel's strengths lie in distributed caching and parallelized builds, making it better suited for more complex projects.

Gradle vs. SBT:

  • Gradle's Groovy-based DSL contrasts with SBT's Scala-based scripting.

  • SBT is optimized for Scala projects, while Gradle's flexibility accommodates a broader range of languages.

  • Gradle's learning curve might be gentler because of its scripting familiarity for many developers.

Gradle vs. Dragonboat:

  • Gradle is a build tool, while Dragonboat is a high-performance Raft library.

  • Gradle focuses on automating build processes, whereas Dragonboat is used for distributed system consistency.

  • Comparing the two is like comparing construction tools to foundational components for distributed systems.

Gradle vs. Go-Zero:

  • Gradle is a general build tool, while Go-Zero is a web/RPC framework.

  • Gradle handles software construction, whereas Go-Zero specializes in high-performance, resilient services.

The Comparison to Gradle is simply because it’s super well-known and widely used within the software development community.
