我已经在我的机器上安装了 STS（Spring tool Suite）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
Please read the following process output to find out more:

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。但仍然得到同样的错误
