Project 'org.springframework.boot:spring-boot-starter-parent:2.3.0.RELEASE' not found

It seems that you are encountering an error related to the Spring Boot starter parent dependency with version 2.3.0.RELEASE. This error usually occurs when the specified dependency cannot be found in the repository or when there is an issue with the dependency declaration.

To resolve this issue, you can try a few troubleshooting steps:

1. Verify the dependency declaration: Double-check the spelling and syntax of the dependency declaration in your project's build file (e.g., pom.xml for Maven or build.gradle for Gradle). Ensure that the version number is correct and matches the available versions in the repository.

2. Clear local repository cache: Sometimes, the issue can be caused by a corrupted local repository cache. You can try deleting the contents of your local repository cache and re-downloading the dependencies. The location of the local repository varies depending on your build tool (e.g., ~/.m2/repository for Maven).

3. Check network connectivity: Ensure that your network connection is stable and capable of accessing the remote repository. Try pinging the repository URL or accessing it via a web browser to ensure that it is accessible.

4. Use a different version: If the specific version (2.3.0.RELEASE) is not available or causing issues, you can try using a different version of the Spring Boot starter parent dependency. Check the official Spring Boot documentation or repository for the available versions and select a suitable one.

If none of these steps resolve the issue, please provide more details about your project setup, build tool, and any relevant error messages, so that I can assist you better.

Could not find artifact org.springframework.boot:spring-boot-starter-parent:pom:2.3.0.M4 in nexus-tencentyun

这个错误提示表明在nexus-tencentyun仓库中找不到org.springframework.boot:spring-boot-starter-parent:pom:2.3.0.M4这个依赖项。可能的原因是该依赖项未被正确部署到nexus-tencentyun仓库中，或者您的项目的pom.xml文件中的仓库配置不正确。

解决此问题的步骤如下：
1.检查您的pom.xml文件中是否正确配置了nexus-tencentyun仓库。您可以在pom.xml文件中添加以下代码块来配置nexus-tencentyun仓库：

<repositories>
    <repository>
        <id>nexus-tencentyun</id>
        <url>http://nexus-tencentyun/repository/maven-public/</url>
    </repository>
</repositories>

2.检查您的依赖项是否正确。您可以在maven仓库中搜索该依赖项，以确保它存在于maven仓库中。如果该依赖项不存在于maven仓库中，则需要手动将其部署到nexus-tencentyun仓库中。

3.如果您确定该依赖项已正确部署到nexus-tencentyun仓库中，并且您的pom.xml文件中的仓库配置正确，则可能是由于nexus-tencentyun仓库无法访问导致的。您可以尝试使用其他maven仓库或检查您的网络连接。
