Android Square Dagger IllegalStateException:无法加载类MyApplicationModule的模块适配器

我在Android项目中使用eclipse和Dagger 1.2.2。我设法用Dagger实现了一个测试应用程序。但通过我的“真实”应用程序，我得到：

java.lang.RuntimeException:无法创建应用程序app.MyApplication:java.lang.IllegalStateException:无法加载类app.MyApplicationModule的模块适配器。请确保已为此模块运行代码生成。：

我还将匕首罐包括在构建路径和工厂路径中。

我发现了我的错误：

---

对于“Java编译器”和“注释处理”，必须选中“启用特定于项目的设置”。现在，我的应用程序抛出了许多其他错误，但Dagger代码生成工具可以工作

对于任何可能和我一样有这个问题的人。我面临的问题是，我没有在gradle构建文件中添加依赖项，以允许dagger在我的类上生成代码：

添加以下内容：

apt 'com.squareup.dagger:dagger-compiler:1.2.2'

更新：如果你不知道apt插件在哪里，你可以把它安装在你的Project gradle文件中。我的依赖项如下所示：

dependencies {
    classpath 'com.android.tools.build:gradle:1.0.0'
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4+'
}

---

如果你使用multiDex，别忘了在你的app.class中激活它

   @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);

        MultiDex.install(this);
    }

这解决了我类似的问题。

project build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4+'
    }

你添加了匕首编译器依赖项吗？@Joseph:是的，我添加了。我一次又一次地检查了所有内容。您还引用了javawriter（）和javax.inject.jar库吗？您使用什么IDE，Eclipse还是Android Studio？@Jospeh：是的，还引用了javawriter和javax.inject。我使用Eclipse Luna。如前所述，我的演示项目可以运行，但我的“真实”应用程序无法启动。为了补充这一点，可以在此处找到android apt的完整文档：为什么不添加“提供的'com.squareup.dagger:dagger compiler:1.2.2'”而不是“提供的”对我不起作用。当我把它改为apt时，一切正常。我不知道。我甚至没有在Android Studio中看到这样的选项。这是因为它是为EclipseAa设计的，Android插件的运行充满了活力，你不需要创建

提供的
配置。另外，不要同时使用提供的
和
apt
。
