kotlin-gradle-plugin 1.6.0构建缓慢

Question

当我将kotlin版本从1.5.30升级到1.6.0时，编译kotlin任务和kapt的任务非常耗时，而且只需要三分钟。我使用--info获取构建I日志。这个部分被调用了数千次，大约需要3分钟，而1.5.30没有这个问题。

Answer 1

在Kotlin 1.6.0中引入的Android项目的编译速度有一个已知的倒退，请参阅KT-49910。也许这就是你所受的影响？

在上述问题中还提供了一种解决方法，即：

buildscript {
  dependencies {
    // Must go before the real KGP plugin!
    classpath("dev.zacsweers:kgp-160-patcher:1.0.0")
  }
}

这将在即将发布的1.6.10中修复。
