无法使用Fresco Included生成签名的apk

Question

我最近将图像加载库从Glide切换到Fresco，现在我无法生成签名的apk。

我一直收到这个错误;

Execution failed for task ':app:transformClassesWithDexForRelease'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Too many classes in --main-dex-list, main dex capacity exceeded 

我的Application课程延伸MultidexApplication，我的proguard-fresco.pro中包含build.gradle个文件。

在使用Fresco之前，我的项目每次都成功构建，但现在我无法生成签名的apk。如何缓解这个问题并让我的项目构建？

我的build.gradle文件如下：

buildscript {
    repositories {
        mavenCentral();
        maven { url 'https://maven.fabric.io/public' }
    }

        classpath "com.newrelic.agent.android:agent-gradle-plugin:5.9.0"
    }
}
