AutoValue in domain module : Cannot resolve symbol generated AutoValue_Foo

I am trying to use AutoValue in the domain module.
Here is the AutoValue class data implementation :

```
import com.google.auto.value.AutoValue;
import org.jetbrains.annotations.Nullable;
import java.util.Date;

@AutoValue
public abstract class Trip {
public abstract int id();
public abstract String name();
public abstract int totalDistance();
@Nullable public abstract Date startDate();
@Nullable public abstract Date endDate();

public static Builder builder() {
return new AutoValue_Trip.Builder().totalDistance(0);
}

@AutoValue.Builder
public abstract static class Builder {
public abstract Builder id(int id);
public abstract Builder name(String name);
public abstract Builder totalDistance(int totalDistance);
public abstract Builder startDate(Date startDate);
public abstract Builder endDate(Date endDate);
public abstract Trip build();
}
}
```

Android Studio cannot find the generated AutoValue_Trip class, so it marks it as an error however, the project builds and runs just fine.

Here is my module's build.gradle file
```
buildscript {
repositories {
mavenCentral()
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath 'me.tatarka:gradle-retrolambda:3.2.3'
classpath "net.ltgt.gradle:gradle-apt-plugin:0.12"
}
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: "net.ltgt.apt"
apply plugin: 'me.tatarka.retrolambda'

//noinspection GroovyUnusedAssignment
sourceCompatibility = 1.8
//noinspection GroovyUnusedAssignment
targetCompatibility = 1.8

configurations {
provided
}

sourceSets {
main {
compileClasspath += configurations.provided
}
}

dependencies {
def domainDependencies = rootProject.ext.domainDependencies
def domainTestDependencies = rootProject.ext.domainTestDependencies

apt domainDependencies.autoValue
compileOnly domainDependencies.autoValue

provided domainDependencies.javaxAnnotation

compile domainDependencies.javaxInject
compile domainDependencies.rxJava
compile domainDependencies.arrow

testCompile domainTestDependencies.junit
testCompile domainTestDependencies.mockito
testCompile domainTestDependencies.assertj
}
```

I have tried using a sourceSet as follows to add the generated build files and folders to the source path:

```
main {
java {
srcDirs += 'src/../build/generated'
}
}
```

But then I was getting compileJava errors.

Has anyone ran into this issue and how did you correct it? Additional info will be provided if necessary.

从 domain 模块的 build.gradle 开始，重现 Android Studio 报告无法解析 AutoValue_Trip 的警告与 build 成功之间的不一致。检查 apt 生成的源如何暴露给 IDE，包括尝试过的生成 sourceSet，并验证 compileJava 仍能成功执行，同时不会引入源路径错误。当 Android Studio 能够识别生成的类且不破坏编译时，即表示完成。
