在IntelliJ中找不到符号变量DaggerAppComponent

Question

I cloned this project https://github.com/robohorse/RoboPOJOGenerator and trying to build with the help of IntelliJ IDE.

It is imported succesfully and downloaded necessary dependencies but it fails when I rebuild it.

Error:(10, 24) java: cannot find symbol
  symbol:   variable DaggerAppComponent
  location: class com.robohorse.robopojogenerator.injections.Injector

I have tried many threads of stackoverflow but didn't work for me. Is this something with gradle or dagger.

buildscript {
    repositories {
        mavenCentral()
        maven { url "http://dl.bintray.com/jetbrains/intellij-plugin-service" }
        maven { url "https://plugins.gradle.org/m2/" }
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
    }

    compile 'com.fifesoft:rsyntaxtextarea:2.6.0'

**@Singleton**
@Component(modules = AppModule.class)
public interface AppComponent {
...
}

Make sure you have @Singleton annotated for your component.
