Each goal may have a separate configuration. That is not to say that the POM cannot affect the flow of the lifecycle - it can. Gone are the days of dozens of disparate build scripts and scattered documentation concerning each individual project. I wonder what the
The answer is, "Of course, but that's a good thing." It is an XML representation of a Maven project held in a file named This is a listing of the elements directly under the POM's project element. If you browse the Maven central repository, you will notice that the classifiers Maven picks the highest version of each project that satisfies all the hard requirements of the dependencies on that project. They are the For a more comprehensive look at what filters are and what they can do, take a look at the If your POM declares a parent, it inherits plugin configuration from either the To illustrate, consider the following fragment from a parent POM:And consider the following plugin configuration from a project that uses that parent as its parent:The default behavior is to merge the content of the Applying those rules to the example, Maven comes up with:You can control how child POMs inherit configuration from parent POMs by adding attributes to the children of the Here is the child configuration with illustrations of the two attributes:Note that these attributes only apply to the configuration element they are declared on, and are not propagated to nested elements.

Along with Maven's other stars that make up the Maven galaxy - a well defined build lifecycle, easy to write and maintain plugins, centralized repositories, system-wide and user-based configurations, as well as the increasing number of tools to make developers' jobs easier to maintain complex projects - the POM is the large, but bright, center.Aspects of this guide were originally published in the Those circumstances are specified via an Before Maven 3.2.2 Activation occurs when one or more of the specified criteria have been met. You often see projects that are both parents and aggregators. This is often used in Maven's generated documentation.Thanks for contributing an answer to Stack Overflow! A Maven phase represents a stage in the Maven build lifecycle.Each phase is responsible for a specific task. If your Maven project uses an SCM system (it does, doesn't it?) org.liquibase:liquibase-maven-plugin:3.8.8:tag. A notifier is the manner in which people are notified of certain build statuses. Notice that The POM contains all necessary information about a project, as well as configurations of plugins to be used during the build process. The ability to abstract all of the aspects of a project into a single artifact is powerful, to say the least.
your coworkers to find and share information. You can run it like this:Exclusions tell Maven not to include the specified project that is a dependency of this dependency (in other words, its transitive dependency). The name of the system property does not necessarily match the name of the mojo parameter. For example, a project may depend upon a jar that has a closed-source license which prevents it from being in a central repository. Feel free to run it yourself when in doubt. Starting with the last elements first:Whereas the repositories element specifies in the POM the location and manner in which Maven may download remote artifacts for use by the current project, distributionManagement specifies where (and how) this project will get to a remote repository when it is deployed. For example, the entire Maven core runs through a single base POM Properties are the last required piece to understand POM basics. The first are artifacts that are used as dependencies of other artifacts. This base POM is known as the Super POM, and contains values inherited by default.. Maven use the effective POM (configuration from super pom plus project configuration) to execute relevant goal. The only element that exists as a prerequisite in POM 4.0 is the Repositories are collections of artifacts which adhere to the Maven repository directory layout.
