什么是“本地存储库”？

简而言之，我现在该怎么做？

Answer 1

您的POM指定了这些存储库：

    <repositories>
        <repository>
            <id>spring-release</id>
            <name>Spring Framework Release Repository</name>
            <url>http://maven.springframework.org/release</url>
        </repository>
        <repository>
            <id>spring-milestone</id>
            <name>Spring Framework Milestone Repository</name>
            <url>http://maven.springframework.org/milestone</url>
        </repository>
        <repository>
        <!-- necessary for Spring Security OAuth SNAPSHOT dependency -->
            <id>spring-snapshost</id>
            <name>Spring Framework Maven Snapshot Repository</name>
            <url>http://maven.springframework.org/snapshot</url>
        </repository>
        <repository>
            <id>objectstyle</id>
            <name>ObjectStyle.org Repository</name>
            <url>http://objectstyle.org/maven2/</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
      </repository>
    </repositories>

这些回购中没有一个包含您尝试下载的插件。您需要在包含插件的pom中添加其他存储库，或者您需要将插件存储在repo中，以便maven可以找到它。

尝试添加http://maven.apache.org/repository/

本地存储库是maven存储它下载的文件的地方。该消息告诉你罐子没有下载。

Answer 2

简单的答案是，因为你使用的是错误的groupId。

<dependency>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
    <version>2.2</version>
</dependency>

Maven：org.codehaus.mojo的POM在哪里：tomcat-maven-plugin：jar：2.2？
