Unable to import Litho KComponent, ComponentScope and other Litho classes

Version

0.49.0

Issues and Steps to Reproduce

1. Create a new project in android studio

2. Select these settings

3. Update your dependencies in the gradle file

dependencies {
    implementation("androidx.core:core-ktx:1.9.0")
    implementation("androidx.appcompat:appcompat:1.6.1")
    implementation("com.google.android.material:material:1.11.0")
    implementation("androidx.constraintlayout:constraintlayout:2.1.4")
    testImplementation("junit:junit:4.13.2")
    androidTestImplementation("androidx.test.ext:junit:1.1.5")
    androidTestImplementation("androidx.test.espresso:espresso-core:3.5.1")

    // Litho
    implementation ("com.facebook.litho:litho-core:0.49.0")
    implementation ("com.facebook.litho:litho-widget:0.49.0")

    // SoLoader
    implementation ("com.facebook.soloader:soloader:0.10.5")

    // For integration with Fresco
    implementation ("com.facebook.litho:litho-fresco:0.49.0")

    // For testing
    testImplementation ("com.facebook.litho:litho-testing:0.49.0")
}

4. Run gradle sync

5. Modify your MainActivity.kt file like so

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import com.facebook.litho.Component
import com.facebook.litho.ComponentScope
import com.facebook.litho.KComponent
import com.facebook.litho.LithoView
import com.facebook.litho.kotlin.widget.Text
import com.facebook.rendercore.dp

class MyActivity : AppCompatActivity() {

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    val lithoView = LithoView.create(this /* context */, MyComponent())
    setContentView(lithoView)
  }
}

class MyComponent() : KComponent() {
  override fun ComponentScope.render(): Component {
    return Text(text = "Hello, World!", textSize = 50.dp)
  }
}

After doing this, I received errors saying "Unresolved reference" for these imports

import com.facebook.litho.ComponentScope
import com.facebook.litho.KComponent
import com.facebook.litho.kotlin.widget.Text

I also couldn't find the classes/imports with "Unresolved reference" in this folder or definition for them

Expected Behavior

I would say the expected behavior is just to import the classes for the tutorial

Thanks for reporting the issue. There is a bug in the maven publish plugin and we just revoked back. Could you please check v0.49.1 if it works for you?
