Could not resolve org.jetbrains.kotlin:kotlin-gradle-plugin:1.8.0 because no repositories are defined

这个错误通常意味着 Gradle 无法找到 Kotlin Gradle 插件的依赖项。您需要在您的 Gradle 构建文件中定义一个 Kotlin Gradle 插件的存储库。您可以在您的 `build.gradle` 文件中添加以下内容：

buildscript {
    repositories {
        mavenCentral() // 或者其他您喜欢的 Maven 存储库
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.8.0"
    }
}

apply plugin: "kotlin"

请确保将 `repositories` 块和 `dependencies` 块添加到 `buildscript` 块中而不是项目的 `repositories` 和 `dependencies` 块中。这是因为 Kotlin Gradle 插件需要在 Gradle 构建自身之前加载。

Could not resolve org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10.

这个错误提示是 Gradle 在构建项目时无法找到 Kotlin Gradle 插件的版本 1.7.10。这可能是因为该版本的插件尚未发布或者您的 Gradle 配置文件中没有正确指定该版本的插件。

您可以尝试更新您的 Gradle 配置文件，确保使用了正确的 Kotlin Gradle 插件版本。例如，您可以将以下内容添加到您的 `build.gradle` 文件中：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10"
    }
}

如果这个版本的插件还没有发布，您可以尝试使用其他版本的插件来代替。您可以在 Kotlin Gradle 插件的官方文档中查找可用的版本信息。

Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.0.6. Required by

This error message indicates that Gradle is unable to find the required version of the Spring Boot Gradle plugin (3.0.6) in any of its configured repositories.

To resolve this issue, you can try the following steps:

1. Make sure that you have specified the correct version of the plugin in your Gradle build file. Double-check the version number to ensure that it matches the version you need.

2. Check your internet connection and ensure that you can access the repository from which the required plugin is being downloaded. If you are behind a proxy, make sure that you have configured Gradle to use the correct proxy settings.

3. Try deleting the Gradle cache directory (located in your home directory under .gradle/caches/) and running the build again. Sometimes, Gradle cache can get corrupted and cause issues.

4. If none of the above steps work, try manually downloading the required plugin JAR file and placing it in your local Gradle repository. You can then refer to the plugin using the `mavenLocal()` repository in your Gradle build file.

I hope this helps!
