Introduction. The Spring Boot Maven Plugin provides Spring Boot support in Apache Maven. It allows you to package executable jar or war archives, run Spring Boot applications, generate build information and start your Spring Boot application prior to running integration tests.
Maven is automation tool which acts as dependency manager for Java applications. So, let's start with creating a simple project but before that make sure you have setup development environment for Spring and installed Eclipse, Java, and Apache Tomcat Server.
Maven's purpose is to provide developers with: A comprehensive, maintainable, reusable, and simple model for projects. A set of tools and plug-ins that can interact with the declarative model.
Spring Boot is compatible with Apache Maven 3.6. 3 or later. If you do not already have Maven installed, you can follow the instructions at maven.apache.org. On many operating systems, Maven can be installed with a package manager.
1 Answer. Maven is a build system for java projects (like ant, gradle, buildr, etc.) Therefore, a 'maven web project' would be a web project that uses maven as a build system, whereas a 'spring web project' is just a spring based web project, and it doesn't say anything about which build system is used.
Dependency injection (Spring) is about injecting dependencies into an instance of a class. Dependency management (Maven) is about retrieving the right library dependencies (other project jar files, including their own dependencies) for your project as a whole. They are unrelated.
The full form of POM is Project Object Model. It is a fundamental unit of work in Maven. pom is a XML file that contains information about the project and configuration details used by Maven to build the project.
Maven Lifecycle: Below is a representation of the default Maven lifecycle and its 8 steps: Validate, Compile, Test, Package, Integration test, Verify, Install, and Deploy.
Before running any goals, Maven checks for the existence of the java command in the path specified by JAVA_HOME or by asking the OS for a default JDK installation. If the executable is not found, Maven terminates with the error.
POM is an acronym for Project Object Model. The pom. xml file contains information of project and configuration information for the maven to build the project such as dependencies, build directory, source directory, test source directory, plugin, goals etc. Maven reads the pom. xml file, then executes the goal.
Maven is a popular open-source build tool that the Apache Group developed for building, publishing, and deploying several projects. Maven is written in Java and is used to create projects written in C#, Scala, Ruby, and so on. The tool is used to build and manage any Java-based project.
A maven is a build tool designed to manage dependencies and the software lifecycle. It is also designed to work with plugins that allow users to add other tasks to the standard compile, test, package, install, deploy tasks. While, Jenkins is designed for the purpose of implementing Continuous Integration (CI).
Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information. Using maven we can build and manage any Java based project.
Default Packaging Types. Maven offers many default packaging types that include a jar, war, ear, pom, rar, ejb, and maven-plugin. Each packaging type follows a build lifecycle that consists of phases. Usually, every phase is a sequence of goals and performs a specific task.
Maven is a tool which is used for building and managing Java Based Projects. Basically to put it in simple words is a way to manage dependency for Java Based Project. Maven can be used when building project with POM (Page Object Model) when working on big projects.
During the build of a project, Maven, without toolchains, will use the JDK to perform various steps, like compiling the Java sources, generate the Javadoc, run unit tests or sign JARs. Each of those plugins need a tool of the JDK to operate: javac , javadoc , jarsigner , etc.
Maven Configuration
The Maven tool uses JDK version 11.0. 10. The default JDK is set to 13.0. 2.
There are three built-in build lifecycles: default, clean and site.
Main Advantages of Maven
Increased performance of projects. Users need not worry about working on different projects in different environments as it makes the process and dependencies easy. Information is accessible easily. It makes the addition of dependencies of JAR files easy.
Maven is a powerful project management tool that is based on POM (project object model). It is used for project build, dependency, and documentation. It simplifies the build process like ANT. But it is too much more advanced than ANT.
JPA is a specification which specifies how to access, manage and persist information/data between java objects and relational databases. It provides a standard approach for ORM, Object Relational Mapping. Spring Boot provides a seemless integration with JPA.
Dependency is nothing but a 'Library' that provides specific functionality that we can use in our application. In Spring-Boot, Dependency Management and Auto-Configuration work simultaneously. It is the auto-configuration that makes managing dependencies supremely easy for us.
A Project Object Model or POM is the fundamental unit of work in Maven. It is an XML file that contains information about the project and configuration details used by Maven to build the project. It contains default values for most projects.
