maven-dependency-plugin的功能

maven-dependency-plugin是
  Maven的一个插件
    提供一系列目标
    用于处理项目依赖
以下是一些maven-dependency-plugin的主要功能：

复制依赖
copy-dependencies目标允许将项目的依赖复制到指定目录
对于创建包含所有依赖的可执行JAR文件或将依赖复制到特定位置以供其他目的

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>3.1.2</version>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/dependencies</outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

解压依赖：

            <version>3.1.2</version>
            <executions>
                <execution>
                    <id>unpack-dependencies</id>
                    <phase>package</phase>
                    <goals>
                        <goal>unpack-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/unpacked-dependencies</outputDirectory>
                    </configuration>
                </execution>
            </executions>

    </plugins>
</build>

查看依赖：
list目标允许列出项目依赖

<build>
