Google Auto Factory：未使用@Provided注释？
所以我正在尝试谷歌汽车工厂，但我得到一个奇怪的错误。
工厂类：
@AutoFactory( className = "MembersAdapterFactoryImpl" ) public class MembersAdapter extends ArrayAdapter { /** * Get an instance of the helper */ private MembersAdapterHelper mMembersAdapterHelper; public MembersAdapter(@Provided MembersAdapterHelper membersAdapterHelper, Context context, int resource, List 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 membersAdapterHelperProvider; @Inject public MembersAdapterFactoryImpl(Provider membersAdapterHelperProvider) { this.membersAdapterHelperProvider = membersAdapterHelperProvider; } public MembersAdapter create(android.content.Context context, int resource, java.util.List members) { return new MembersAdapter(membersAdapterHelperProvider.get(), context, resource, members); } }
这似乎很好，但我得到了这个例外。

我在我的android gradle文件中将其列为编译：
// 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'
为什么编译器会抱怨的任何线索？
看起来问题主要是注释处理/匕首/缺少javaxjar子。
我应该感谢Github上的cypressious发布他的gradle build.gradle文件，lifesaver。

你需要使用
（i）使用Dagger 2.0时，依赖性问题仍然存在，但您不需要任何apt。 所以跳到3。
apply plugin: 'com.neenbedankt.android-apt' -
看起来使用“提供”的依赖关系不适用于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）导致类似的东西
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，你必须把它带入你的依赖项：
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，Google Auto Factory在我的项目中可用。
