How can I manually import Maven dependency packages into my project?

To manually import Maven dependencies, you can follow these steps:

1. Open the website of Maven Central Repository (https://search.maven.org/) or any other Maven repository website, and search for the dependencies that need to be imported.
2. Once you have found the target dependency package, copy its Maven coordinates, typically including GroupId, ArtifactId, and Version information.
3. Navigate to the root directory of the project and locate the pom.xml file.
4. Add a new tag in the section of the pom.xml file, and paste the copied Maven coordinates into it.

<dependencies>
    ...
    <dependency>
        <groupId>依赖包的GroupId</groupId>
        <artifactId>依赖包的ArtifactId</artifactId>
        <version>依赖包的Version</version>
    </dependency>
    ...
</dependencies>

1. Save the pom.xml file.
2. Go back to the command line interface, navigate to the project’s root directory, and run the following command to manually download dependencies.

mvn dependency:resolve

Maven will automatically parse the pom.xml file, and download the necessary dependencies to the local Maven repository.

Please note that manually importing dependencies may lead to version conflicts or dependency errors, so it is recommended to manage project dependencies through Maven’s dependency management feature.
