带有 Proguard 的 Android Studio 中的 Dagger 警告即使没有直接使用 Dagger

Question

我的项目不再使用 Proguard 优化进行编译。 正如您将在下面看到的，它提到了dagger，但我没有直接使用与此相关的任何东西。我最近一次更新了许多依赖项。

如果我使用dontwarn 来抑制dagger 相关行，我会收到以下消息（我尝试使用--info、--debug 和--scan 获取更多行，但输出具有相同的细节）：

> Task :app:transformClassesAndResourcesWithProguardForRelease FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> java.io.IOException: java.lang.ArrayIndexOutOfBoundsException: 2

我也试过最新的（6.1.1）Proguard（覆盖默认的），结果是一样的。

可能是什么原因？

应用的build.gradle 内容：

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {

    compileSdkVersion 29//28
    buildToolsVersion "29.0.0" //"28.0.3"
    defaultConfig {
        applicationId "myapp"
        minSdkVersion 16
        targetSdkVersion 28

        multiDexEnabled true
        manifestPlaceholders.crashlyticsEnabled = "true"
    }
    buildTypes {

        }
    }

    dexOptions {
        javaMaxHeapSize "2g"
    }
}
configurations {
    all*.exclude group: 'com.google.guava', module: 'listenablefuture'
}

        exclude group: 'org.json', module: 'json'
    }
}

apply plugin: 'com.google.gms.google-services'

更新 我将依赖项恢复到他们以前的版本。问题是 implementation 'com.google.firebase:firebase-inappmessaging-display:18.0.0' 如果我将版本更改为17.1.0，“匕首”相关问题就会消失。如果我把它改成17.2.0，问题又来了。

更新2 这可能是 Firebase 的一个错误。我已经联系了他们，他们创建了一个内部错误报告。当我有答案时，我会更新这个问题。

Answer 1

当我将新版本的 firebase crashlytics 添加到我的项目时，我遇到了一个非常相似的问题，输出与您的相同，我所做的是在 pro-guard 文件中为 dagger 库添加了一个 dontwarn，因为这个匕首问题根本没有影响项目，它只是 pro-guard 混淆任务的问题。

#dagger
-dontwarn  dagger.android.**

这解决了我的问题。

Answer 2

因为您不知道您的 dagger 版本是什么，所以很难在您的项目中找到确切的问题，但您可以在 progaurd-rules.pro 文件中添加以下代码，您的项目将成功构建。

-ignorewarnings
-keep class * {
    public private *;
}

试着告诉我。希望它对你有用。 快乐编码:)
