How to Integrate Custom External JARs into Your Maven Project for Version Control?

Custom External JAR Integration with Maven

Adding external JAR files to a Maven project is a common task, especially when working with non-public repositories. For your specific scenario, we will explore two options, both ensuring both your project and the library are version controlled.

1. In-Project Repository:

To maintain the library within your project and version control, you can create an in-project repository. Add the following to your pom.xml:

<code class="xml"><repository>
    <id>in-project</id>
    <name>In Project Repo</name>
    <url>file://${project.basedir}/libs</url>
</repository>

<dependency>
    <groupId>stuff</groupId>
    <artifactId>library</artifactId>
    <version>1.0</version>
</dependency></code>

This will add the lib directory under your project folder as a repository and automatically install the library.

2. System Scope with External Path:

If you prefer to store the JAR externally, you can use the system scope:

<code class="xml"><dependency>
    <groupId>stuff</groupId>
    <artifactId>library</artifactId>
    <version>1.0</version>
    <systemPath>${lib.location}/MyLibrary.jar</systemPath>
    <scope>system</scope>
</dependency></code>

Specify the system path of the JAR file using the ${lib.location} property, but you won't need to run mvn install:install-file.

Eclipse Issue Resolution:

If Eclipse doesn't recognize the dependency after adding it to the POM, you can try the following:

• Clean and rebuild the project (right-click > Clean)
• Manually add the JAR file to your Eclipse project classpath (right-click > Properties > Java Build Path)
• Refresh the Maven dependencies (Window > Show View > Other > Maven)
