kotlin-gradle-plugin 1.6.0 構建緩慢

Question

當我把kotlin版本從1.5.30升級到1.6.0的時候，compilekotlindebug任務和kapt的任務比較耗時，只需要三分鍾。 我使用 --info 獲取構建日志。 這部分被調用了數千次，大約需要 3 分鍾，而 1.5.30 沒有這個問題。

Answer 1

Kotlin 1.6.0中引入的 Android 項目的編譯速度存在已知的回歸，請參見KT-49910 。 也許這就是你受到的影響？

上述問題中還提供了一種解決方法，即：

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

這將在即將發布的1.6.10中修復。
