Unable to add external jar into application jar file

Question

I use external jar jimObjModelImporterJFX.jar , because it's not hosted on Maven repository and I'm adding it with maven dependency like below

    <dependency>
        <groupId>jimObjModelImporterJFX</groupId>
        <artifactId>jimObjModelImporterJFX</artifactId>
        <scope>system</scope>
        <version>1.0</version>
        <systemPath>${path}</systemPath>
    </dependency>

I could not add it in IntelliJ by Project Structure -> Modules -> Dependencies -> + because later on I'd have errors during maven task.

Then I have plugin to add dependencies (but it's not adding and I don't know why, but on other topics people say that it should)

    <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <archive>
                    <manifest>
                        <mainClass>myMainClass</mainClass>
                    </manifest>
                </archive>
            </configuration>
            <executions>
                <execution>
                    <id>make-assembly</id>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

After that I run maven task clean compile assembly:single and when it's done I have a jar in target folder.

When I run it from cmd I have an error

Caused by: java.lang.ClassNotFoundException: com.interactivemesh.jfx.importer.ImportException
    at java.net.URLClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 22 more

It's because my application jar file doesn't contains this library inside. Structure is like: archive |-groupid.artifactid (.class files here) |-layouts (with .fxml file because it's javaFX app) |-META-INF (with MANIFEST.MF)

How to put this jimObjModelImporterJFX.jar into my app?

Answer 1

system dependencies will never end up in the resulting jar by definition. They are supposed to be explicitly provided.

You can add the jar to your local .m2 repository using the maven command line util mvn like this

mvn install:install-file -Dfile=<path-to-jar-file> \
                         -DgroupId=<yourGroupId> \
                         -DartifactId=<yourArtifactId> \
                         -Dversion=<yourVersion> \
                         -Dpackaging=jar

and then use the "normal" dependency notation

    <dependency>
        <groupId>yourGroupId</groupId>
        <artifactId>yourArtifactId</artifactId>
        <version>yourVersion</version>
    </dependency>
