3. Add the following code to the dependencies section:

   dependencies {
    implementation files('libs/your-jar-file.jar')
   }

   Replace your-jar-file.jar with the actual name of the JAR file you added.

4. Save the build.gradle file.
5. Sync the project by clicking on Build > Rebuild Project or by running the command ./gradlew build in the terminal.
