How to Seamlessly Add a Third‑Party SDK Jar to Your Maven Project

In many projects you may need to use a third‑party SDK that is provided only as a JAR and cannot be uploaded to a Maven repository.

Step 1: Place the third‑party JAR under src/main/resources (or a subdirectory such as src/main/resources/jar).

Step 2: Add a system‑scoped dependency in pom.xml that points to the JAR file.

<dependency>
    <groupId>taobao-sdk-java</groupId>
    <artifactId>taobao-sdk-java</artifactId>
    <version>1.0</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/src/main/resources/jar/taobao-sdk-java.jar</systemPath>
</dependency>

Step 3: Configure the Maven build plugin to include system‑scoped JARs when packaging.

<build>
    <finalName>${project.artifactId}</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <fork>true</fork>
                <!-- value true means include system‑scoped JARs -->
                <includeSystemScope>true</includeSystemScope>
            </configuration>
        </plugin>
    </plugins>
</build>

After completing these steps the external SDK is packaged with the application and can be used like any other library.
