我正在尝试使用STS 3.4.0版开始使用Gradle，但是当我尝试为我的项目添加Gradle支持时，子菜单中的所有选项都变灰了。我尝试将该项目删除并导入为Gradle项目，但是当我单击Build Model按钮时，会得到以下堆栈跟踪：
FAILURE: Build failed with an exception.
* Where:
Build file '/Users/xxx/Documents/development/sample/build.gradle' line: 13
* What went wrong:
A problem occurred evaluating root project 'sample'.
> org.gradle.api.tasks.TaskContainer.create(Ljava/lang/String;Ljava/lang/Class;)Lorg/gradle/api/Task;
* Try:
Run with --info or --debug option to get more log output.
* Exception is:
org.gradle.api.GradleScriptException: A problem occurred evaluating root project 'sample'.

BUILD FAILED

我猜这就是在我右键单击导入为简单Eclipse项目时选项变灰的原因，因为该项目中还没有.java文件，而
gradle CLI命令似乎没有问题（运行了build、eclipse和cleanEclipse几次）。欢迎提供任何指导。
