什么是“本地存储库”？

简而言之，我现在该怎么办？

Answer 1

您的 POM 指定这些存储库:

    <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>

这些存储库都不包含您尝试下载的插件。您需要向包含插件的 pom 添加其他存储库，或者需要将插件存储在存储库中，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。该消息告诉您该 jar 尚未下载。
