What are the steps for Maven project packaging?

Maven project packaging steps: 1. Create a Maven project; 2. Add a Java source folder; 3. Add a resource folder; 4. Add the corresponding folder directory; 5. Add the corresponding configurations in different environments. file; 6. Add the packaging environment in the pom.xml file; 7. Set the resource file configuration; 8. Packaging; 9. Confirm the generated package; 10. Deploy and run. Detailed introduction: 1. Create a Maven project. First, use your favorite IDE to create a new Maven project, etc.

The packaging steps of the Maven project are as follows:

1. Create a Maven project: First, use your favorite IDE (such as Eclipse, IntelliJ IDEA etc.) Create a new Maven project. In the IDE, there is usually an option for "Maven Project", select it and follow the wizard to complete the project creation.

2. Add the Java source folder: In the project structure, find the src/main/java directory, which is the location where the Java source code is stored. Place your Java source code files in this directory.

3. Add resource folder: In the project structure, find the src/main/resources directory, which is the location where the project resource files are stored. You can place configuration files, pictures and other resources in this directory.

4. Add the corresponding folder directory: Add other folder directories as needed, such as src/main/webapp for Web projects.

5. Add configuration files corresponding to different environments: In the src/main/resources directory, you can create configuration files for different environments, such as local.properties, test.properties and prod .properties, etc., to adapt to different environmental needs.

6. Add the packaging environment in the pom.xml file: Open the project's pom.xml file, which is the core file of the Maven project. In the pom.xml file, you need to add the relevant configuration of the packaging environment. This usually includes specifying packaged plug-ins, setting plug-in parameters, etc. For example, you can add the maven-jar-plugin plugin to package Java projects, or add the maven-war-plugin plugin to package Web projects.

7. Set resource file configuration: In the pom.xml file, you can set the configuration of resource files to ensure that resource files are processed correctly during the packaging process. For example, you can set the path to the resource folder and include/exclude resource files, etc.

8. Packaging: After completing the above steps, you can start packaging the project. In the IDE, you can usually run Maven's packaging command directly. In the command line, enter the root directory of the project, and then enter the following command:

mvn clean install

This command will perform the cleaning and installation operations of the project, and finally generate a packaged file (such as a jar package or a war package ).
9. Confirm the generated package: After the packaging is completed, you can find the generated package file in the target directory of the project. Check whether the generated package file meets expectations, including package name, version number and other information.
10. Deployment and operation: For Web projects, you can deploy the generated war package to the Web server, and then start the server for testing and running. For non-Web projects, you can run the generated jar package directly.

The above are the basic packaging steps of the Maven project. Depending on the specific needs of the project and the environment configuration, other additional configuration and operations may be required. Please ensure that you have correctly installed Maven and configured the relevant environment variables so that you can successfully perform the above steps.
