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.

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

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

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

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