堆栈溢出社区用户，我的项目中的spring安全实现有一个奇怪的问题：
如果我加上这个：

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-security -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

在pom.xml上
发生这种情况：
sts:spring工具套件，在pom的第一行显示此错误：

<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">
Failure to transfer org.springframework.security:spring-security-core:jar:5.4.2 from https://repo.maven.apache.org/maven2 was cached in the local 
 repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact 
 org.springframework.security:spring-security-core:jar:5.4.2 from/to central (https://repo.maven.apache.org/maven2): Permission denied: no further information 
 org.eclipse.aether.transfer.ArtifactTransferException: Failure to transfer org.springframework.security:spring-security-core:jar:5.4.2 from https://
 repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are 
 forced.

我所做的：
在project>maven>updateproject上右键单击run project>clean
一旦我删除了Spring Security 依赖项，错误就消失了，但是我正在尝试在我的学习课程项目上实现Spring Security ，但是由于上面解释的原因，我不能，请帮助！
谢谢你在福沃德
