All Spring Boot projects use spring-boot-starter-parent as a parent in pom. xml file. Parent Poms allow us to manage the following things for multiple child projects and modules: Configuration: It allows us to maintain consistency of Java Version and other related properties.
What is a POM? 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.
POM is the simplest packaging type. The artifact that it generates is itself only, rather than a JAR, SAR, or EAR. There is no code to test or compile, and there are no resources the process. The default goals for projects with POM packaging are shown in Table 4.3, “Default Goals for POM Packaging”.
The pom. xml describes the project's dependencies and tells you how to build it. (Dependencies are third-party software required by the project. Some common examples are JUnit and JDBC.
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.
You really need something like Maven or Gradle to work with Spring Boot. The jar/war it creates has a special packaging and specialized way of starting. Without Maven or Gradle you would need to make sure you also replicate this yourself, else the delivered artifact won't work.
settings. xml contains system and/or user configuration, while the pom. xml contains project information. All build configuration ends up in the pom.
<parent> and <dependencies> elements are two distinct things but it exists all the same an important relation between them. Simply said the parent defines the parent pom of the current pom and dependencies defines the actual dependencies of the current pom.
Maven has two types of dependencies: Direct dependencies: These dependencies are explicitly included in a pom. xml file in the <dependencies> section. Transitive dependencies: A project included as a dependency in a larger project can declare its own dependencies in a pom.
A parent pom. xml file (or super POM) in Maven is used to structure the project in order to avoid redundancies and duplicate configurations by using inheritance between different pom. xml files. If any dependency or properties are configured in both - parent and child - pom.
The POM file is named pom. xml and should be located in the root directory of your project. A project divided into subprojects will typically have one POM file for the parent project, and one POM file for each subproject.
pom packaging acts as the container for other sub-modules which are themselves are packaged in a jar or war files. pom packaging can have sub-modules that have different packaging. You need to include '<packaging>pom</packaging>' in pom. xml file. They are declared and listed in the 'modules' tag.
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.

POM stands for Project Object Model, and it is the core of a project's configuration in Maven. It is a single configuration XML file called pom. xml that contains the majority of the information required to build a project.
Overview. The maven builds lifecycle is the tasks performed when the maven build commands are executed. The maven build lifecycle is divided into stages known as build phases. A build phase is made up of objectives. Maven goals are specific tasks that contribute to the creation and management of a project.
Maven's Multi-Module Project
The submodules are regular Maven projects, and they can be built separately or through the aggregator POM. By building the project through the aggregator POM, each project that has a packaging type different from pom will result in a built archive file.
In the POM, right-click anywhere in the editor to open the context menu and select Maven | Show Dependencies. Alternatively, press Ctrl+Alt+Shift+U or Ctrl+Alt+U . In the diagram window, IntelliJ IDEA displays the sub project and all its dependencies including the transitive ones.
They execute during the build process and should be configured in the <build/> element of pom. xml. They execute during the site generation process and they should be configured in the <reporting/> element of the pom.
A POM file must use 2 spaces for each indentation. Because POM snippets are often used in documentation to show the user how to configure something, it is important that these snippets aren't too wide.
xml is the configuration for TestNG testing framework (e.g. defining test suites, test listeners, etc...) pom. xml is the configuration for Maven build tool (e.g. defining build plugins, compile and test dependencies, build profiles, etc...)
A plugin is an extension to Maven, something used to produce your artifact (maven-jar-plugin for an example, is used to, you guess it, make a jar out of your compiled classes and resources). A dependency is a library that is needed by the application you are building, at compile and/or test and/or runtime time.
