spring-boot - Gradle无法同步Spring Boot项目

Question

我正在尝试从intelij中的start.spring.io导入带有gradle的新项目，它无法下载任何依赖项或导入插件。我看到来源列表是空的。

知道如何解决吗？

   $ ./gradlew build

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\Jarek\Downloads\demo\build.gradle' line: 3

* What went wrong:
Plugin [id: 'org.springframework.boot', version: '2.2.2.RELEASE'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.springframework.boot:org.springframework.boot.gradle.plugin:2.2.2.RELEASE')
  Searched in the following repositories:
    Gradle Central Plugin Repository

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

您可能已为gradle切换了OFFLINE MODE。请关闭离线模式并在IDE终端上运行./gradlew build。
