To add local jar files to a Maven Project we have to follow some steps. In this blog, we will learn how to add local jar files to a Maven Project in detail:
Table of Contents:
Method 1: Install the JAR file into the Local Maven Repository
We can install the JAR file manually into the Local Maven Repository:
Command
mvn install:install-file -Dfile=<desired_filepath>
Example
mvn install:install-file –Dfile=C:\dev\app.jar -DgroupId=com.intellipaat.java.tutorials -DartifactId=intellipaat-java-app-Dversion=1.0
Now, to add the dependency to your Maven project, use these particular lines in your pom.xml file:
Code:
<dependency>
<groupId>com.intellipaat.java.tutorials</groupId>
<artifactId>intellipaat-java-app</artifactId>
<version>1.0</version>
</dependency>
Explanation: In this method, we have run the command to install the JAR file into the Repository.
Method 2: Use system Scope
We can also add local jar files to a Maven Project using system scope. Let’s understand this with an example:
If the JAR package is located in <PROJECT_PARENT_FOLDER>/lib. Then, after this, you have to add the required dependency in our pom.xml file using these lines:
Code:
<dependency>
<groupId>com.intellipaat.java.tutorials</groupId>
<artifactId>intellipaat-java-app</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${basedir}/lib/yourJarName.jar</yoursystemPath>
</dependency>
Explanation:
We have to Replace lib/your-local-jar-file.jar with the relative path to our JAR file.
Conclusion
So far in this blog, we have learned two different methods of adding local jar files to a Maven Project.

FAQs
Q.1. What is maven?
Maven is a build automation and dependency management tool for Java projects, simplifying project setup, build processes, and library management.
Q.2. What does the maven do?
Maven helps build Java projects and manage the libraries they need. It automates tasks like compiling code, running tests, and adding required tools or dependencies.
Q.3. Why is Maven used?
Maven is used to simplify project management by automating tasks like building, testing, and adding required libraries. It saves time and ensures consistency in handling dependencies and project setups.
Q.4. Is Maven a compiler?
No, Maven is not a compiler; it is a build and project management tool. It uses compilers like javac to compile Java code as part of its build process.
Q.5. What is a JAR file in a Maven project?
A JAR (Java Archive) file is an archive of compiled Java classes and resources employed in Java projects. Dependencies in Maven are typically maintained through online repositories, but local JAR files may be added manually when needed.
Q.6. Why would I need to add a local JAR file to a Maven project?
You may have to include a local JAR if it is a proprietary library, not available in public repositories, or custom-developed for particular use cases.
Q.7. What are the prerequisites for adding a local JAR file to a Maven project?
You require Maven installed, a properly formed pom.xml file in your project, and the JAR you want to add.
