我们正在从Android Gradle插件2.3.3迁移到Gradle插件3.0.1。 目前，可以使用插件2.3.3与Proguard或使用插件3.0.1但不使用Proguard来构建项目。应用程序包含两个模块。 Proguard之后有大约一百个警告：
Warning: there were 70 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning: there were 10 instances of library classes depending on program classes.
You must avoid such dependencies, since the program classes will
be processed, while the library classes will remain unchanged.
(http://proguard.sourceforge.net/manual/troubleshooting.html#dependency)
Warning: there were 34 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile the code.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedprogramclassmember)
而忽略它们不是解决方案。在这种情况下，我在应用程序启动时得到了这个：
