To import local JAR files in bulk, you can follow these steps:

  1. Create a “lib” folder in the root directory of your project (if it does not already exist).
  2. Copy the local JAR file to the lib folder that will be introduced.
  3. Add the following code block to the pom.xml file of your project to import all JAR files in the lib folder:
<dependencies>
   <dependency>
      <groupId>local</groupId>
      <artifactId>local-jars</artifactId>
      <version>1.0</version>
      <scope>system</scope>
      <systemPath>${project.basedir}/lib/*.jar</systemPath>
   </dependency>
</dependencies>

In this code block, we are using the groupId “local”, artifactId “local-jars”, and importing all JAR files in the lib folder with version “1.0”. The systemPath element specifies the path of the JAR files, which uses ${project.basedir} to access the absolute path of the project root directory.

  1. Navigate to the root directory of the project using Maven’s command line tool, and run the following command to build and install the local JAR package:
mvn clean install
  1. Now, you can use these local JAR files in your project. Maven will automatically read the pom.xml file and add these JAR files to the project’s classpath.

Please note that due to the use of system scope, Maven will not publish these JAR files to the Maven repository. Therefore, only the current project can use them, and other projects will not be able to automatically resolve the dependencies of these JAR files.
