路径为的项目:在根项目“gradle tutorial”中找不到projecta

我是刚认识Gradle的人,正在关注这个 Gradle tutorial 它给出了下面的例子,在我的/GooLeTeal/Budio.GooLLE文件中复制/粘贴

project(':projectA') {
   task hello
}
task hello

println tasks.getByPath('hello').path
println tasks.getByPath(':hello').path
println tasks.getByPath('projectA:hello').path
println tasks.getByPath(':projectA:hello').path

当我奔跑

$ gradle -q hello

我明白了

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/myuser/gradle-tutorial/build.gradle' line: 1

* What went wrong:
A problem occurred evaluating root project 'gradle-tutorial'.
> Project with path ':projectA' could not be found in root project 'gradle-tutorial'.

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

我确实创建了一个~~/GoeldTeal/StudioA/Budio.GoeLLE文件,但仍然有同样的错误。

我错过了什么?

我找到的笔记 Project with path ':mypath' could not be found in root project 'myproject' 但不知道如何使这个答案适用于我的简单的一个文件/一个目录案例。
