安装maven和maven插件

Question

我已经在windows和安装works.However上下载了Apache 3.1.1，我想启动jetty，但是我想有一种方法必须首先告诉Maven在哪里找到jetty，但是我还是继续了，我得到了这个

C:\maven>mvn jetty:run

我必须告诉maven在哪里找到jetty，以及如何安装这个版本的plugin?.In，我发现插件directory.Should有一个吗？

Answer 1

您需要将插件添加到pom.xml中。这里是文件。

Answer 2

尝试在pom.xml中添加插件

<plugin>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <version>9.0.5.v20130815</version>
</plugin>
