什么是“本地存儲庫”？

簡而言之，我現在該怎么辦？

Answer 1

您的POM指定了以下存儲庫：

    <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>

這些存儲庫均不包含您嘗試下載的插件。 您需要在包含插件的pom中添加其他存儲庫，或者需要將插件存儲在存儲庫中，以便maven可以找到它。

嘗試添加http://maven.apache.org/repository/

本地存儲庫是maven存儲下載的文件的位置。 該消息告訴您未下載jar。

Answer 2

簡單的答案是，因為您使用的是錯誤的groupId。

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