【问题描述】：

我正在我的应用程序中集成 dagger 当我运行应用程序时遇到这个问题

java.lang.RuntimeException: Unable to instantiate application com.mine.parsexml.ParseApplication: java.lang.ClassNotFoundException: Didn't find class "com.mine.parsexml.ParseApplication" on path: DexPathList[[zip file "/data/app/com.mine.parsexml-4NxKMOI9esXH_ar6UHYk5w==/base.apk"],nativeLibraryDirectories=[/data/app/com.mine.parsexml-4NxKMOI9esXH_ar6UHYk5w==/lib/x86, /system/lib, /system/product/lib]]

这是应用程序类 - 也已在清单中声明

class ParseApplication: Application()

【问题讨论】：

我在 2.40.1 版本中也遇到了这个错误

@Denny 检查我的答案是否适合你

我实际上纠正了我的问题。我没有将域模块包含到主应用程序模块中

【参考方案1】：

我的问题是匕首依赖的关键字错误 因为编译器必须使用 kapt 而不是实现

改变了

implementation "com.google.dagger:hilt-android-compiler:2.39.1"

到

kapt "com.google.dagger:hilt-android-compiler:2.39.1"

【讨论】：

救我一命。我还使用了implementation "com.google.dagger:hilt-android-compiler:2.39.1" 而不是kapt "com.google.dagger:hilt-android-compiler:2.39.1"。值得一提的是，官方文档根本不清楚需要哪些依赖项和插件
