Question

所以我尝试了谷歌汽车工厂，但我得到了一个奇怪的错误。

工厂类：

@AutoFactory(
    className = "MembersAdapterFactoryImpl"
)
public class MembersAdapter extends ArrayAdapter<Member> {

    /**
     * Get an instance of the helper
     */
    private MembersAdapterHelper mMembersAdapterHelper;

    public MembersAdapter(@Provided MembersAdapterHelper membersAdapterHelper,
                          Context context,
                          int resource,
                          List<Member> members){
        super(context, resource, members);
        mMembersAdapterHelper = membersAdapterHelper;
    }
}

生成的类：

package me.magneto.groups.adapters;

import javax.annotation.Generated;
import javax.inject.Inject;
import javax.inject.Provider;
@Generated("com.google.auto.factory.processor.AutoFactoryProcessor")
public final class MembersAdapterFactoryImpl {
  private final Provider<MembersAdapterHelper> membersAdapterHelperProvider;
  @Inject
  public MembersAdapterFactoryImpl(Provider<MembersAdapterHelper> membersAdapterHelperProvider) {
    this.membersAdapterHelperProvider = membersAdapterHelperProvider;
  }
  public MembersAdapter create(android.content.Context context, int resource, java.util.List<me.magneto.groups.models.group.Member> members) {
    return new MembersAdapter(membersAdapterHelperProvider.get(), context, resource, members);
  }
}

这似乎完全正常，但我得到了这个例外。

我将此列为我的android gradle文件中的编译：

// factories
compile 'com.google.auto.factory:auto-factory:0.1-beta1'

// dagger
compile 'com.squareup.dagger:dagger:1.2.0'
provided 'com.squareup.dagger:dagger-compiler:1.2.0'

编译器为什么会抱怨的任何线索？

Answer 1

看起来问题主要是注释处理/匕首/缺少javax罐子。

我应该感谢Github上的cypressious发布他的gradle build.gradle文件，救生员。

您需要使用

（i）使用Dagger 2.0时，依赖性问题仍然存在，但您不需要任何apt。所以请跳到3。

apply plugin: 'com.neenbedankt.android-apt'
看起来使用'provided'作为依赖项不适用于Google自动工厂，而是需要使用'apt'插件来代替依赖项。这包括匕首（如果你正在使用它，我假设）导致类似
```
apt 'com.google.auto.factory:auto-factory:0.1-beta1'
compile 'com.google.auto.factory:auto-factory:0.1-beta1'

compile 'com.squareup.dagger:dagger:1.2.0'
apt 'com.squareup.dagger:dagger-compiler:1.2.0'
```
现在这是另一件大事，在Dagger 1.2.1 / 1.2.2不受支持，所以我不得不最终使用Dagger 1.2.0。
最后一步必须将其纳入您的依赖项：

compile 'javax.annotation:jsr250-api:1.0'

看起来Generated注释不包含在Java8中？我不是100％，或者这就是Gradle默认情况下不包括'Generated'注释作为注释处理的一部分。

无论如何，在完成这三件事之后，我的项目中会出现Google Auto Factory。

Google Auto Factory：未使用@Provided进行注释？
