1、选择

org.apache.maven.archtypes:maven-archtype-webapp

2、禁止远程下载

archetypeCatalog=internal

目的是不远程下载，否则始终【downloading maven plugins...】

3、jetty

<build>
    <finalName>myprj</finalName>
    <plugins>
      <plugin>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>9.3.27.v20190418</version>
        <configuration>
          <httpConnector>
            <port>9999</port>
          </httpConnector>
          <scanIntervalSeconds>10</scanIntervalSeconds>
          <webAppConfig>
            <contextPath>/myprj</contextPath>
          </webAppConfig>
        </configuration>
      </plugin>
    </plugins>
  </build>
