英文:
Gradle init project not able to add dependencies to "app" subproject
问题
我使用Gradle 8.1.1创建了一个新项目，选择了应用程序(2)、Java(3)、没有多个子项目、Groovy DSL、JUnit 5、相同的项目和源包名称以及Java 11。
我将Apache Commons添加到app/build.gradle，并希望在App.java中调用StringUtils，但失败了。起初我以为是VS Code有问题，但运行./gradlew build也失败了，错误如下：
gradle-basic-structure-dep-error\app\src\main\java\gradle\basic\structure\dep\error\App.java:10: error: incompatible types: boolean cannot be converted to String
return StringUtils.isBlank(" ");
^
1 error
FAILURE: Build failed with an exception.
这是完整的示例链接：https://github.com/cwansart/gradle-basic-structure-dep-error
为什么会失败？这可能是生成的代码中的错误吗？
英文:
I created a new Gradle 8.1.1 project with gradle init chosing the options application (2), Java (3), no multiple subprojects, Groovy DSL, JUnit 5,the same project and source package name and Java 11.
I added Apache Commons to app/build.gradle and wanted called StringUtils in App.java but it failed. I first thought VS Code had an issue, but running ./gradlew build fails also with:
gradle-basic-structure-dep-error\app\src\main\java\gradle\basic\structure\dep\error\App.java:10: error: incompatible types: boolean cannot be converted to String
return StringUtils.isBlank(" ");
^
1 error
FAILURE: Build failed with an exception.

Why is it failing? Might this be an error in the generated code?

以下是已翻译的内容：
因为 getGreeting() 的返回类型是 String，而 StringUtils.isBlank(" ") 的返回类型是 boolean。
所以你应该像下面这样更改返回类型：
public boolean getGreeting() {
return StringUtils.isBlank(" ");
}
此外，你应该使用像Intelij或Eclipse这样的IDE来编写Java代码。它会为你突出显示和报告这种类型的错误。
英文:
It's because the return type of getGreeting() is String, and return type of StringUtils.isBlank(" ") is a boolean.
So you should change the return type like below
public boolean getGreeting() {
return StringUtils.isBlank(" ");
}
Beside, you should write java code using IDE like Intelij or Eclipse. It will highlight and report this kind of error for you

To clarify the issue: in VS Code the imports were marked red and not found, regardless of the error I did mention by Jeremie.
I tried it on a different computer on which it worked. I tried it again on my working machine in a new profile with a clean checkout and it worked again. It seems that the Java or Gradle VSCode plugin had an issue, I guess?
