Maven is a build automation tool for Java. The Spring Boot Maven plugin provides various capabilities for developing/executing Spring Boot projects with Maven. In this article, we will take a closer look at this plugin. What is the Spring Boot Maven Plugin The Spring Boot Maven plugin simplifies the process of building, packaging, and running Spring Boot applications using Maven.  Some of the things that you can do using this plugin are: Build/package Spring Boot applications as executable JAR or WAR files. These files include all necessary dependencies, making it easy to deploy and run Spring Boot applications. Start an embedded application server (such as Tomcat or Jetty) and deploy your Spring Boot application on it during development and testing. Manage and resolve dependencies specific to Spring Boot, ensuring that you have compatible versions of Spring Boot libraries and other related dependencies. Simplify configuration management by setting Spring Boot properties directly in yo...

Maven is a popular build automation and project management tool primarily used for Java projects. Java developers often run the maven clean install command to build Java projects. In this blog post, I will try to explain what the maven clean install command does. Let us break down this command.   Clean This part of the command tells Maven to clean the project. Cleaning a project means removing all the build artifacts (compiled classes, libraries, generated files, etc.) from previous builds. This ensures that you start with a clean slate before building the project again. It’s particularly useful to eliminate any potential issues caused by leftover artifacts from previous builds.   Install   This part of the command tells Maven to build and package the project and then install the resulting artifact(s) into the local Maven repository. The local repository is a local cache where Maven stores project dependencies and artifacts. When you use “install,” the ...

In my earlier article, we learned how to create a Java web project in Eclipse and how to add Maven support to it.  In this article, we will learn how to create a Maven web project using archetype selection. Create Maven Web Project In Eclipse Step 1 – In Eclipse, Click on File > New > Other . Click on Maven Project . Click Next : Step 2 – The following screen is displayed. Click Next : Step 3 – In the Filter text box, type “ maven-archetype-webapp “.  Select “ org.apache.maven.archetypes “. Click Next : Step 4 – Enter Group Id and Artifact Id . Click Finish : This creates a web project with the required directory structure: Now you can add the necessary dependencies to your pom file as explained in this post. So for example, if you are creating a Spring application, you can add Spring dependencies. You can also use this as a template to create any web application with Maven support.

Maven is a build management system. The Maven wrapper can be used to install the right version of Maven. In this article, we will be learning about the wrapper and its benefits. Need for Maven Wrapper Normally, applications require specific Maven versions for the application to run successfully. So, developers need to ensure that the right Maven version is installed and available on the path. The Maven wrapper solves this issue. Using the wrapper, you just need to specify the desired Maven version. The wrapper then automatically installs the specified Maven version and makes it available on the path. Wrapper Installation Steps Let us first learn about the steps to install the wrapper. Open a command prompt/terminal window and navigate to the directory where you want to install the wrapper Run the following command: mvn -N io.takari:maven:wrapper 3. This command installs files related to the wrapper. So, you will see the following files/folders: .mvnw – This folder contains wrapper...

In this blog post, I will be demonstrating how to deploy an application to Tomcat in Eclipse. In order to deploy a Maven application in Tomcat in Eclipse, you can follow the same steps. Step 1 – Setup Tomcat in Eclipse if not already setup. Refer to this blog post for detailed steps Step 2 – Right-click on “Tomcat Server” at the bottom and click Add/Remove: Step 3 – Select Your project name and click “Add”: Step 4 – Click on Finish. Step 5 – Start Tomcat by right-clicking and clicking on “Start”. If the server starts successfully, you should see a message similar to the following in the console:   Further Reading Fundamentals of Apache Tomcat Beginning with Eclipse IDE Apache Tomcat Beginners to Advanced Java Programming in Eclipse

In this blog post, I will be explaining how to create a web project in Eclipse with Maven support. Create a Dynamic web project Step 1 -Click on “File –> New –> Other” Step 2 – Click on Dynamic Web Project Step 3 – Type some project name Step 4 – Click on Next Step 5 – Click on “Next” Step 6 – “Click on Finish”. This will create a project as follows: Create web.xml Sometimes, Eclipse may not automatically create the web.xml file. So if this file is not present in your web-inf folder, you need to follow these steps. Step 1 – Right click on project –> Java JEE Tools –> Generate Deployment Descriptor Stub This will create a web.xml file as follows: Add Maven Support Step 1 – Right-click on Project –> Configure –> Convert to Maven Project Step 2 – Click Finish This will add a pom file to the project as follows: Now you can add the necessary dependencies t...

In this blog post, I will be giving step by step directions on how you can add Maven dependencies via Eclipse. What is Maven Maven as you might probably know is a dependency management tool. It automatically downloads the necessary jar files for you.So you do not need to download the jar files and add them to your classpath explicitly. Maven uses a file named as pom.xml. This file has all the project configuration. The external jar files that are needed for the project need to be added as dependencies in this pom file. So for example, if you need Hibernate JAR files in your project, you will need to add Hibernate dependencies in the pom file. Maven then automatically downloads the jar files and adds them to the classpath. So let’s get started. Adding Maven Dependencies Via Eclipse Step 1 – Create your Maven project via Eclipse (Refer this post)   Step 2 – Right click on pom.xml. Click on Maven –> Add Depenency Step 3 – Enter group id, artifact id a...
