Simplify Your Script Build With Gradle

Learn more about how to simplify your script build with Gradle

Gradle is an open-source build automation system that builds upon the concepts of Apache Ant and Apache Maven, and introduces a Groovy-based, domain-specific language (DSL), instead of the XML form used by Apache Maven to declare the project configuration. This post will cover how easy it is to use this tool, and how to migrate your Maven project to Gradle to run it on Platform.sh.

Gradle is an excellent build tool with which we can automate Java applications using a clean DSL. But it’s essential to mention that Maven is still a valid and mature tool, and Gradle doesn’t deprecate Maven. There are several tutorials where both devices are compared, and you can see several companies going back and forth between Maven and Gradle. The answer to which one is the better tool is still uncertain. What matters is that at Platform.sh, you can choose both to move your Java application to the cloud.

Starting With Apache Maven

Apache Maven is a build or a total project management tool that scores over its predecessors such as ANT for Java builds with the following advantages:

  • Useful when multiple JAR files are required for builds
  • Resolving recursive dependencies during build time
  • Creating project structures that are standardized
  • Building, publishing, and deployment of applications
  • Supports lifecycle of an application along with plugins

Top 5 Course to Learn Apache Maven for Java Developers

Apache Maven, or more commonly known as just "Maven," is an important tool for Java programmers. It allows you to build your project, manage dependencies, generate documentation, and a lot more. I can vouch for Maven's usefulness because I have come from the pre-Maven world of Software development, where you need to manage all the JAR files required by your project. It may seem easy to you that just download the JAR file, but it's not so easy in practice. For example, you added a new library in your project — say the Spring Framework, which also needs log4j, but you thought log4j is already there, so you didn't do anything, only to realize that your application is not starting anymore and throwing long and convoluted errors. This can happen because of version mismatch, like Spring needed a higher version of log4j than available in your project.

This is just a tiny example that shows how manually managing dependencies can create nightmares. Maven took away all those pain by not only automatically downloading those JAR files for you but also created a central place, known as a Maven repository, to store those JAR files for better management.

Maven is not just a dependency management tool; it's, in fact, much more than that. The biggest advantage of using Maven is the following convention, which makes software development easy.
