在 Spring Tool Suite 中导入 gradle 项目时遇到错误“无法启动守护进程”

Question

我已经在我的机器上安装了 STS（Spring 工具套件）并尝试导入现有的 gradle 项目，但它给了我一个错误。我已经检查了 jdk 路径环境变量。

错误是

 Loading Gradle project preview failed due to an error connecting to the Gradle build.
Could not fetch model of type 'GradleBuild' using Gradle distribution 'https://services.gradle.org/distributions/gradle-3.4.1-bin.zip'.

Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at https://docs.gradle.org/3.4.1/userguide/gradle_daemon.html

我已经安装了builship 插件。我也尝试过两种方式，默认 gradle 支持 STS 和 buildship 集成。但仍然遇到同样的错误

只需重新安装 jdk 即可解决我的问题。
