安装Maven和Maven插件

Question

我已经在Windows XP上下载了Apache Maven 3.1.1，并且安装正常。但是，我想启动码头，但我想有一种方法可以告诉maven首先在哪里找到码头，但是无论如何我还是继续了。

C:\maven>mvn jetty:run

我是否必须告诉maven在哪里可以找到码头以及如何安装码头插件？在此版本的maven中，我会找到插件目录。应该有一个吗？

Answer 1

您需要将插件添加到pom.xml中。 这是文档。

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>
