How to configure non repository maven files (like intersystems-jdbc-3.1.0.jar)

Some InterSystems Java libraries are not available in public maven repositories, like intersystems-jdbc-3.1.0.jar. In this case, to configure your Java Maven dependency, copy the external file to your project (for a folder visible to the classpath, like resources) and use <systemPath>. Follow the sample:

<dependency>
            <groupId>com.intersystems</groupId>
            <artifactId>intersystems-jdbc</artifactId>
            <version>3.1.0</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/intersystems-jdbc-3.1.0.jar</systemPath>
</dependency>

It is necessary enable your build to system dependencies. See:

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <includeSystemScope>true</includeSystemScope>
                </configuration>
            </plugin>
        </plugins>
    </build>

Now, when you build your project, the external jar files will be included to the target binary.
