Maven

Maven

A Maven is a tool for managing Java projects. Maven centralizes your project’s build, reporting, and documentation. It prefers convention over configuration, which means it’s opinionated and forces you to develop applications in a consistent style with explicit specifications.

Ant is an alternative to Maven. Ant is not opinionated, and as a consequence, its setup is more flexible. This, however, implies that developers must create all instructions from scratch. Unless your project has a unique build mechanism, Maven is the better option.

Gradle

Gradle

Gradle is a Java project automation tool. It extends the capabilities of Apache Ant and Apache Maven. It is also the Android platform’s primary build tool.

Features:

  • Better dependency modeling using the Java Library plugin minimizes the size of the build classpath.
  • It includes a remote build cache as well as easy administration tools.
  • Gradle Wrapper enables Gradle builds to be run on computers where Gradle is not installed. It supports multi-project builds as well as incomplete builds.
  • It adapts quickly to any construction.
  • Its intelligent classpath aids in avoiding needless compilation while a library’s binary interface remains unchanged.

Jenkins

Jenkins

Jenkins is the most popular open-source automation server for building, testing, and deploying code. It may simply integrate into your current tech architecture and eliminate manual, boring chores due to its large number of plugins.

Jenkins is designed in Java, therefore it is readily portable to many major platforms and is utilized in many of the projects for which the original Jenkins inventor intended Jenkins to be built. Jenkins also has a robust community of hundreds of thousands of users that are eager to help you with any questions you may have.

Spark

Spark

Spark is a dependable Java-based framework for creating web applications. It enables Java developers to build web apps without having to write boilerplate code.

Features:

  • Support for many languages
  • It includes tools for interactive and declarative searches, streaming data, and machine learning.
  • For batch processing, Spark code may be reused.
  • Spark streaming is capable of handling real-time stream processing.
  • It has support for real-time stream processing.
