java - Google AutoValue 无法识别 AutoValue_CustomType

Question

我试图在我的 Android Studio 项目中使用 Google AutoValue 生成 HomeKey，但它没有忽略 AutoValue_HomeKey() (请参阅下面的注释代码)。使用的gradle版本:4.10.1

我的 Android 项目基于此示例: https://github.com/Zhuinden/simple-stack/tree/master/simple-stack-example-basic-java-fragment

我是否忘记应用插件，或者实现了错误的包？

HomeKey 类:

import com.google.auto.value.AutoValue;

@AutoValue
public abstract class HomeKey extends BaseKey {
    public static HomeKey create() {

        /*
            Cannot resolve AutoValue_HomeKey()
        */
        return new AutoValue_HomeKey(); 
    }

    @Override
    protected BaseFragment createFragment() {
        return new HomeFragment();
    }
}

BaseKey 类:

import android.os.Bundle;
import android.os.Parcelable;

import gamf.tankolaskonyvelo.fragment.BaseFragment;

public abstract class BaseKey implements Parcelable {
    public String getFragmentTag() {
        return toString();
    }

    public final BaseFragment newFragment() {
        BaseFragment fragment = createFragment();
        Bundle bundle = fragment.getArguments();
        if (bundle == null) {
            bundle = new Bundle();
        }
        bundle.putParcelable("KEY", this);
        fragment.setArguments(bundle);
        return fragment;
    }

    protected abstract BaseFragment createFragment();
    }
}

Answer 1

您正在使用托管在 clojars 上的 annotationProcessor 'frankiesardo:auto-parcel:1.0.3'。

因此，您应该将以下存储库添加到 build.gradle 中的 allprojects { block 中:

maven { url "https://clojars.org/repo/" }

那么你应该尝试重建项目。

成功构建后，应显示注释处理生成的类。

(如果您检查存储库的根 build.gradle，那么您会看到示例可能使用的 Maven 存储库:

repositories {
    google()
    mavenCentral()
    maven { url "https://clojars.org/repo/" }
    maven { url "https://jitpack.io" }
    maven { url 'https://maven.google.com' }
    jcenter()
}

因此，即使库本身托管在 jitpack.io 上，示例的依赖项 auto-parcel 也位于 clojars 上)
