How to introduce your own lib in java maven

Introducing your own library (lib) into a Java Maven project can follow the following steps:

1. Prepare your own library

First, make sure your library exists in the appropriate format, such as a JAR file. If your library is a project in development, you can package it into a JAR file.

2. Place the library file

Place your library file (JAR) in a suitable location. The following methods can usually be considered:
A specific folder in the project directory, such as a lib folder.
Place the library file in the local Maven repository. If you choose this method, you can use Maven's installation command to install the library to the local repository. For example, suppose your library JAR file is named, you can run the following command from the command line to install it to your local repository:

mvn install:install-file -Dfile= -DgroupId= -DartifactId=your-artifact-id -Dversion=your-version -Dpackaging=jar

where, your-artifact-id and your-version need to be replaced with appropriate values ​​to identify your library.

3. Introduce libraries in Maven project

Add dependencies to the project's file:
If your library is placed in a specific folder in the project directory, you can use system-wide dependencies to introduce xml

   <dependency>
       <groupId></groupId>
       <artifactId>your-artifact-id</artifactId>
       <version>your-version</version>
       <scope>system</scope>
       <systemPath>${basedir}/lib/</systemPath>
   </dependency>
  • Here
  • Your-artifact-id and your-version also need to be set according to actual situations
  • ${basedir}/lib/ is the path of the library file in the project.

If your library is already installed in the local Maven repository, you can import xml like other Maven dependencies

   <dependency>
       <groupId></groupId>
       <artifactId>your-artifact-id</artifactId>
       <version>your-version</version>
   </dependency>

Through the above steps, you can introduce your own libraries in your Java Maven project. It should be noted that using system-wide dependencies may cause some maintenance problems, because this dependency is not managed by Maven, so when possible, try to install the library to the local Maven repository and introduce the dependencies in a standard way.
