Question

我的Java项目有许多依赖项，例如Box2d，OpenGl和OpenAl
我在plugin中定义了pom.xml的以下列表，因此使用Maven来管理项目。
注意：我在pom.xml底部列出了依赖项，但不在此处。

我按照此文档开始使用：http://maven.apache.org/plugins/maven-shade-plugin/examples/executable-jar.html

<plugins>
    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
            <source/>
            <target/>
        </configuration>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>2.3</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <transformers>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                            <mainClass>com.app.game.Main</mainClass>
                        </transformer>
                    </transformers>
                </configuration>
            </execution>
        </executions>
    </plugin>
</plugins>

当我运行mvn package时，会创建jar，即target/test-0.1.jar 它实际上包含所有jar个依赖项，并在包的根目录中包含原生.so和.dll个库。

但是当我尝试从CLI运行应用程序时，我得到UnsatisfiedLinkError例外我错过了pom中的内容吗？

[rob@work target]$ java -jar test-0.1.jar

在plugins中使用以下一组POM.xml实现了我的目标......

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <descriptors>

            <goals>
