3. Add dependencies: In the root directory of the Maven project, find the file named pom.xml. This is the configuration file of the Maven project, which is used to define the project's dependencies, build configuration, etc.
4. Add dependency element: In the pom.xml file, find the dependencies tag. Within this tag, add a new dependency element to define the information of the jar package to be imported. The following is an example:
<dependencies> <dependency> <groupId>com.example</groupId> <artifactId>example-jar</artifactId> <version>1.0.0</version> </dependency> </dependencies>
In the above example, groupId specifies the group identifier of the jar package, artifactId specifies the component identifier of the jar package, and version specifies the version number of the jar package. You need to replace this information with the corresponding information of the jar package you actually use.
5. Save the pom.xml file: Save the changes to the pom.xml file.
6. Build the project: Enter the project root directory on the command line and execute the following command to build the project:
mvn clean install
Maven will automatically parse the dependencies and download all Required jar package. If all goes well, you should be able to successfully build the project and import the required jar packages.
7. Verify the import: After importing the jar package into the project, you can verify whether the jar package has been imported correctly by writing code. Make sure you can access and use the classes and methods in the imported jar package.
Please note that if you are using an IDE, such as Eclipse or IntelliJ IDEA, you can directly import the jar package in the IDE without modifying the pom.xml file. The specific import method may vary from IDE to IDE. You can refer to the documentation or tutorials of the relevant IDE to learn how to import jar packages in the IDE.
In addition, if you are using private jar packages or jar packages that are not available in public repositories, you may need to configure a local repository or private repository to store and access these jar packages. In this case, you need to install the jar packages into a local or private repository and reference them in the pom.xml file. For specific operations, please refer to the instructions on configuring local warehouses and private warehouses in the Maven documentation.
