【问题描述】:
我正在关注android developers tutorial来实现一个本地房间数据库。
我目前正在处理 Setup,因此正在更改我的依赖项。 但是,一旦我同步了 app build.gradle,它就会抛出一个错误。
A problem occurred evaluating project ':app'.
> Could not find method ksp() for arguments [androidx.room:room-compiler:2.3.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.
如何将它指向 ksp() 方法?
以前我在使用 kapt() 时遇到了同样的问题,但通过添加 id kotlin-kapt 解决了它,但我还没有找到 ksp() 所需的依赖项。
我的应用 build.gradle 看起来像这样。相应的部分在代码sn-p的下部并标有//rooom <---------
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
//Room
id 'kotlin-kapt'
