1、使用tomcat-maven-plugin需要在pom.xml檔案中project>build節點下新增以下程式碼：

 <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.tomcat.maven</groupId>
          <artifactId>tomcat6-maven-plugin</artifactId>
          <version>2.3-SNAPSHOT</version>
        </plugin>
        <plugin>
          <groupId>org.apache.tomcat.maven</groupId>
          <artifactId>tomcat7-maven-plugin</artifactId>
          <version>2.3-SNAPSHOT</version>
        </plugin>
      </plugins>
    </pluginManagement>

（a）在project>repositories節點下加如下配置資訊

<repository>
	<id>people.apache.snapshots</id>
	<url>
		http://repository.apache.org/content/groups/snapshots-group/
	</url>
	<releases>
		<enabled>false</enabled>
	</releases>
	<snapshots>
		<enabled>true</enabled>
	</snapshots>
</repository>
 

（b）在project>pluginRepositories下新增如下配置資訊

<pluginRepository>
	<id>apache.snapshots</id>
	<name>Apache Snapshots</name>
	<url>
		http://repository.apache.org/content/groups/snapshots-group/
	</url>
	<releases>
		<enabled>false</enabled>
	</releases>
	<snapshots>
		<enabled>true</enabled>
	</snapshots>
</pluginRepository>
 

正確的pom.xml檔案為：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

	<groupId>MavenHelloWorld</groupId>
	<artifactId>MavenHelloWorld</artifactId>
	<packaging>war</packaging>
	<version>0.0.1-SNAPSHOT</version>
	<name>MavenHelloWorld Maven Webapp</name>
	<url>http://maven.apache.org</url>
	<dependencies>
		<dependency>

	</dependencies>
	<repositories>
		<repository>

			</releases>
			<snapshots>
				<enabled>true</enabled>
			</snapshots>
		</repository>
	</repositories>
	<pluginRepositories>
		<pluginRepository>

		</url>
			<releases>
				<enabled>false</enabled>
			</releases>
			<snapshots>
				<enabled>true</enabled>
			</snapshots>
		</pluginRepository>
	</pluginRepositories>
	<build>
		<finalName>MavenHelloWorld</finalName>
		<pluginManagement>
			<plugins>
				<plugin>
					<groupId>org.apache.tomcat.maven</groupId>
