android – Why in my Java class library I can not import dependency classes?

The steps I took to create a pot was as follows:

In Android Studio, I created a new blank project.

Once the project was created, I created a new module "Java Library".
No build.gradle in reference to the created lib, I added dependencies, for example:

apply plugin: java-library & # 39;

dependencies {
FileTree implementation (dir: 'libs', include: ['*.jar'])
implementation com.bla.bla .... & # 39;
}

I clicked on "Synchronize Now" and until then everything was perfect.

But in the Java class, I can not see the implementation classes and I can not import classes.

If I create a normal project in Android Studio and I add the same dependency in build.gradleit works well, I can import and use classes. Why is this happening?
