Project build error: Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete, origin: ...app/build/intermediates/transforms/TheRouter/uat/debug/353.jar:../GrpcLog.class

[yorkvolvo]

Can't build the project with TheRouter version 1.1.2

复现问题

在项目中引用我们的一个 sdk 后编译报错，我在 TheRouter demo 中添加 sdk 引用后同样的编译报错，看起来是 TheRuter 相关的编译报错。。。

error log:

Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete, origin: 

...app/build/intermediates/transforms/TheRouter/uat/debug/353.jar:../GrpcLog.class

GrpcLog 代码

import kotlin.String

internal sealed class GrpcLog : LogString {
  public override val category: String = "Grpc"
}

internal class Grpclog : GrpcLog {
  private val `value`: String

  public override val message: String
    get() = "${value}"

  public constructor(`value`: String) {
    this.`value` = `value`
  }
}

看起来是R8在desugar过程中的问题，应该跟SDK无关，关闭R8再试试呢

[JackBro3306]

这边也遇到了同样的问题， 用的是 id("cn.therouter.agp8") version "1.2.2" apply false AGP版本为8.2.1 android.enableR8属性已被弃用
