得到“请更正警告编译”android调试，但我已经 - 在Proguard文件中发出警告

Question

当我编译我的应用程序时，我得到一个org.gradle.api.tasks.TaskExecutionException：任务执行失败'：******：transformClassesAndResourcesWithProguardFor ***** Debug'。正如你所看到的，我在proguard文件中有所有-dontwarn符号，但是当我收到调试警告时，看起来我没有添加它们。我得到了所有依赖项的警告：

警告：com.itextpdf.awt.PdfGraphics2D：找不到超类或接口java.awt.Graphics2D

我哪里错了？

这是我的gradle文件：

似乎在构建特定风味维度时未找到proguard规则文件。不知道为什么。

通过在加载proguard规则文件时指定根文件夹来解决此问题：

buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), "$project.rootDir/proguard-rules.pro"
        }
        debug {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), "$project.rootDir/proguard-rules.pro"
        }
    }

希望这有助于其他人，花了一整天才弄明白。
