创建 Maven 项目时不可解析的父 POM

Question

我已经使用STS4创建了一个maven项目，但是创建时，第5行文件pom.xml中出现错误：

Non-resolvable parent POM for com.example:demo2:1.0: org.springframework.boot:spring-boot-starter-parent:pom:2.6.13 failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.6.13 from/to central (https://repo.maven.apache.org/maven2): repo.maven.apache.org

这是我的文件 pom.xml `

<?xml version="1.0" encoding="UTF-8"?>
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.13</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>
    <artifactId>demo2</artifactId>
    <version>1.0</version>
    <name>demo2</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>11</java.version>
    </properties>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

我应该怎么做才能解决这个问题？非常感谢

你必须删除*-无法使用org.springframework.boot:spring-boot-starter-parent:pom:2.6.13 的本地 Maven 存储库中的文件。

看看例如（如果您的本地 Maven 存储库是 .m2）

.m2/org/springframework/boot/spring-boot-starter-parent/2.6.13/
