Could not find artifact org.springframework.boot:spring-boot-starter-parent:pom:2.1.0 in aliyunmaven

It seems that you're facing a problem with finding the artifact "org.springframework.boot:spring-boot-starter-parent:pom:2.1.0" in the "aliyunmaven" repository.

To resolve this issue, there are a few possible solutions you can try:

1. Check the repository URL: Make sure that the repository URL you are using is correct and accessible. Sometimes, repositories may have changed or been discontinued, so double-checking is crucial.

2. Clear your local Maven repository: It's possible that your local repository may have cached outdated or incorrect metadata. You can try deleting the specific artifact folder from your local repository and then triggering a fresh download.

3. Try a different repository: If the "aliyunmaven" repository is not working, you can try using a different Maven repository like Maven Central or JCenter. Update your project's `pom.xml` file to include the desired repository and try again.

Here's an example of adding Maven Central as a repository in your `pom.xml`:

<repositories>
    <repository>
        <id>central</id>
        <name>Maven Central Repository</name>
        <url>https://repo.maven.apache.org/maven2</url>
    </repository>
</repositories>

Remember to update your `dependency` section with the correct artifact details.

I hope one of these solutions helps you resolve the issue. Let me know if you have any further questions!
