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...

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。

如果您想交付应用程序jar的一个包，以及它的所有依赖项和一些调用MainClass的脚本，请查看appassembler-maven-plugin。

下面的配置将为windows和Linux生成启动应用程序的脚本(生成的路径引用所有依赖项jar，下载所有依赖项(到target/appassembler下面的lib文件夹中)。然后，可以使用组装插件将整个appassembler目录打包到一个zip文件中，该文件将与jar文件一起安装/部署到存储库中。

将目录目录打包为zip文件的程序集描述符(在src/main/assembly中)如下:

<assembly>
  <id>archive</id>
  <formats>
    <format>zip</format>
  </formats>
  <fileSets>
    <fileSet>
     <directory>${project.build.directory}/appassembler</directory>
     <outputDirectory>/</outputDirectory>
    </fileSet>
  </fileSets>
</assembly>

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>

你所需要的只是在pom.xml的build/plugins里面的以下代码片段:

<plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <phase>prepare-package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/lib</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

当您运行时，上面的代码将在包阶段运行

mvn clean package

依赖项将被复制到代码片段中指定的outputDirectory，在本例中为lib。

如果只是偶尔这样做，则不需要更改pom.xml。简单地运行以下命令:

mvn clean package dependency:copy-dependencies

重写默认位置${project.build。目录}/依赖，添加一个名为outputDirectory的系统属性，即

    -DoutputDirectory=${project.build.directory}/lib
