Question

Here is my error

Project build error: Non-resolvable parent POM for com.aftermath:guli_parent:0.0.1-SNAPSHOT: org.springframework.boot:spring-boot-starter-parent:pom:2.2.1.RELEASE failed to transfer from http://maven.aliyun.com/nexus/content/groups/public during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of alimaven has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.2.1.RELEASE from/to alimaven ( http://maven.aliyun.com/nexus/content/groups/public ): Connect timed out and 'parent.relativePath' points at no local POMJava(0)

I found a similar error and tried command mvn dependency:purge-local-repository but also encountered an error

I don't know what to do next. This is the first time I use vscode to run Java Maven project. Is there any configuration missing? Ask for help

You have a duplicate dependency in lines 96 & 171

        <dependency>
            <groupId>com.aliyun.oss</groupId>
            <artifactId>aliyun-sdk-oss</artifactId>
            <version>${aliyun-sdk-oss.version}</version>
        </dependency>
