.maven's knowledge and understanding
*POM
Maven's core configuration file defines the project's dependencies, plugins, parent project and build goals and other information;
Uniquely identify an item or dependency by coordinates
*Dependency management
Automatically download and manage third-party libraries (such as jar packages) to resolve dependency conflicts; support local repositories, remote repositories and private repositories
*Plugin mechanism
Maven's functions are implemented through plug-ins (such as compilation, testing and packaging, etc.)
Life cycle
Three sets of independent life cycles, each cycle contains multiple stages, and when a certain stage is executed, all previous stages will be automatically executed.
life cycle
Clean up the build products, such as the target directory
Core stage:
*pre-clean——clean——post-clean
Commonly used commands: mvn clean
(Build) Lifecycle
Core stage:
*compile: compile source code
*test: Run unit tests, requiring corresponding dependencies, plugins and unit test classes
*package: Package to generate distributable files
*install: Install the package to the local repository for other projects to depend on
