Maven is a project management and build automation tool, mainly used for Java project construction, dependency management and project document generation. It provides a standardized way to build and manage projects, simplifying the project building process so that developers can focus on writing code instead of manually configuring and managing project dependencies.
Maven uses the Project Object Model (POM) to describe the project. POM is an XML file that contains the metadata and dependency information of the project. Through POM, Maven can automatically download and manage project dependencies, solving the pain point of manual dependency management in Java projects.
Maven also provides a set of plugins to support various tasks such as compiling source code, running tests, packaging applications, and more. These plug-ins can be configured and used in projects as needed, and these tasks can be performed through simple command line instructions.
You can check the Maven version in the following ways:
1. Use the command line: Enter mvn -v or mvn --version in the command line, and then press Enter. This will display the Maven version information as well as the Java version information.
2. Check the environment variables: On some systems, you can check the environment variables to find the Maven version information. Type echo $MAVEN_HOME at the command line and press Enter. This will display the Maven installation directory.
3. Using IDE: If you are using an integrated development environment (IDE), such as IntelliJ IDEA or Eclipse, you can find the Maven version information in the IDE's configuration or settings. In IntelliJ IDEA, you can view Maven version information in "File" -> "Settings" -> "Build, Execution, Deployment" -> "Build Tools" -> "Maven". In Eclipse, you can view Maven version information in "Window" -> "Preferences" -> "Maven".
4. View the pom.xml file: If you have access to the project's pom.xml file, you can find the Maven version information by searching for the
The above are ways to check the Maven version under different circumstances. With these methods, you can easily find which Maven version you are using and ensure you are using the correct version when building and managing your project.
