看一看Maven依赖项插件，特别是依赖项:复制依赖项目标。查看标题为“依赖:复制依赖的魔咒”下的示例。将outputDirectory配置属性设置为${basedir}/target/lib(我相信，您必须进行测试)。

希望这能有所帮助。

mvn install dependency:copy-dependencies 

工作为我在目标文件夹中创建的依赖目录。喜欢它!

最好的方法取决于你想做什么:

If you want to bundle your dependencies into a WAR or EAR file, then simply set the packaging type of your project to EAR or WAR. Maven will bundle the dependencies into the right location. If you want to create a JAR file that includes your code along with all your dependencies, then use the assembly plugin with the jar-with-dependencies descriptor. Maven will generate a complete JAR file with all your classes plus the classes from any dependencies. If you want to simply pull your dependencies into the target directory interactively, then use the dependency plugin to copy your files in. If you want to pull in the dependencies for some other type of processing, then you will probably need to generate your own plugin. There are APIs to get the list of dependencies, and their location on disk. You will have to take it from there...

你可以使用Shade插件创建一个超级罐子，你可以在里面捆绑你所有的第三方依赖。

这是一种用于嵌入严重依赖关系的重载解决方案，但Maven的Assembly Plugin对我来说是有用的。

@Rich Seller的回答应该是有效的，尽管对于更简单的情况，你应该只需要从使用指南中摘录以下内容:

<project>
    <build>
        <plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.2.2</version>
                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

如果你想偶尔这样做(因此不想改变你的POM)，试试这个命令行:

mvn dependency:copy-dependencies -DoutputDirectory=${project.build.directory}/lib

如果省略最后一个参数，依赖项将放在target/dependencies中。
