com.android.tools.r8.CompilationFailedException: Compilation failed to complete

接入SDK遇到报错：

com.android.tools.r8.CompilationFailedException: Compilation failed to complete, position: Lcom/github/gzuliyujiang/oaid/IRegisterCallback;onComplete()V

解决方案：

在主项目的build.gradle中添加JDK1.8的支持

compileOptions {
     //加载了gradle构建工具的情况下可以使用
     sourceCompatibility JavaVersion.VERSION_1_8
     targetCompatibility JavaVersion.VERSION_1_8
 }
