我的诡异错误

我用intellij 直接把廖老师的zip包解压 然后open as intellij project -> 然后到根目录底下，运行：mvn dependency:get

报错是： Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:get (default-cli) on project web-servlet-embedded: You must specify an artifact, e.g. -Dartifact=org.apache.maven.plugins:maven-downloader-plugin:1.0 -> [Help 1]

我看了一下pom文件里面并没有引用这个plugin，感觉是mavin自己给找到的依赖性。我在pom里面增加了如下一段，还是一样的错误

<dependency>   <groupId>org.apache.maven.plugins</groupId>   <artifactId>maven-dependency-plugin</artifactId>   <version>2.8</version>   <scope>provided</scope></dependency>

我的java --version出来是这样：

java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) Client VM (build 25.261-b12, mixed mode)

我的mvn -v 这样

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

Maven home: D:\Java\apache-maven-3.6.3\bin\..

Java version: 12.0.1, vendor: Oracle Corporation, runtime: c:\Program Files\Java\jdk-12.0.1

Default locale: zh_CN, platform encoding: GBK

OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

请各位不吝赐教。感谢感谢。已经折腾了几个小时了。
