我在 Android Studio 中使用 Kotlin。我无法在连接了 moshi 库的情况下编译项目。https://github.com/square/moshi

告诉我，我做错了什么？？我可以在控制台中看到：

:app:packageInstantRunResourcesDebug UP-TO-DATE
:app:checkManifestChangesDebug
:app:transformClassesWithAndroidGradleClassShrinkerForDebug

首先，您minifyEnabled true在调试中设置，但minifyEnabled false在发布中设置。那没有意义。要么都设置为 要么true都设置为false。

第二件事是。你知道做什么minifyEnabled吗？它在您的项目中启用了 ProGuard。有关更多详细信息，请参见此处。

然而。您有两种选择来解决该问题。minifyEnabled以正确的方式设置false或应用 ProGuard。

从添加开始

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

到你的build.gradle.

通过在您的proguard-rules.pro.
