android studio 4.2 纯 Java module 一直报红 但是能正常运行

今天升级 Android studio 4.2 之后 项目里面有 2 个 module 是 java-library 的 一直报错

感觉是 jdk 找不到了 改成 android-library 才好

什么情况？以后 Android Studio 不支持写纯 java 项目了？？

环境：Android Studio4.2

gradle:4.2.0

异常配置

plugins {
id 'java-library'
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
}

sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8

修复后配置

plugins {
id 'com.android.library'
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
}

sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8
