Docker, Maven, and Jenkins are some of the most popular tools in the DevOps and Java world. Maven helps to organize your project and provide support to build and deploy Java projects while Jenkins can provide continuous integration and delivery by completely automating build and deploy projects.
As a Programmer, particularly Java developer, it’s very important that you know both Maven and Jenkins because every other company is using it and not knowing these technologies will only put you behind other candidates if you go for a job.
If you have yet to learn Maven and Jenkins then you have come to the right
place, In this article, I will tell you 10 free course you can take to
learn Maven and Jenkins online and some other key tools like Robot Framework, Docker, and DevOps, but before that, let’s understand what is Maven and Jenkins and what are their purpose.
Apache Mavenis based upon convention over configuration principle. It provides the plugins to build, test, and deploy your project but the most important benefit of Maven is dependency management.
It not only provides a Maven central library to organize all third-party
Java JAR files but also downloads the dependency for any Java project
automatically at the build time. Which means you don’t need to manually
download your JAR files and deal with several errors related to version
mismatch e.g. UnsupportedClassVersionError.

For example, if your project is dependent on Spring 5 then it will not only
download the Spring 5 JAR files from maven central library but also all
dependent JARs required by Spring itself. This is known as transitive dependency management.
Jenkinsis one of the most popular tools for doing continuous integration on
ANY platform or technology but it has become a standard in Java world.
One of the things which makes Jenkins so popular and useful is its
flexibility. It can handle just about any kind of build or continuous
integration process you can think of through the hundreds of plugins
that are available.
