如何摆脱增量注释处理请求的警告? [英] How to get rid of Incremental annotation processing requested warning?

问题描述

我刚刚开始使用android开发并尝试使用Room库.从昨天开始我就面临着这个警告消息

I have just started using android development and trying to use Room library. Since yesterday I am facing this warning message

w:[kapt]已请求增量注释处理，但支持 禁用，因为以下处理器不是增量处理器: androidx.lifecycle.LifecycleProcessor(NON_INCREMENTAL)， androidx.room.RoomProcessor(NON_INCREMENTAL).

w: [kapt] Incremental annotation processing requested, but support is disabled because the following processors are not incremental: androidx.lifecycle.LifecycleProcessor (NON_INCREMENTAL), androidx.room.RoomProcessor (NON_INCREMENTAL).

我已尝试研究和修复，但无法避免此错误，这是我的grale.build文件.请提出建议/建议我在做什么错了.

推荐答案

kotlin-gradle-plugin版本1.3.50中有一个错误，如@Necrontyr所述.只需将build.gradle(Project)中的kotlin_version降级到1.3.41.

There is a bug in kotlin-gradle-plugin version of 1.3.50 as @Necrontyr mentioned. Just downgrade the kotlin_version in build.gradle(Project) to 1.3.41.
