问题背景

当我新建了一个项目，然后由于某些原因，需要迁移androidx到旧版的Android Support Library，当我调试完，一直报错，后放弃该新建项目，打开我之前可正常bulid的项目，改回androidx
当我再次build时，报错信息如下：

Duplicate class kotlin.collections.jdk8.CollectionsJDK8Kt found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.internal.jdk8.JDK8PlatformImplementations found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.jvm.jdk8.JvmRepeatableKt found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.random.jdk8.PlatformThreadLocalRandom found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.streams.jdk8.StreamsKt found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.streams.jdk8.StreamsKt$asSequence$$inlined$Sequence$1 found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.streams.jdk8.StreamsKt$asSequence$$inlined$Sequence$2 found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.streams.jdk8.StreamsKt$asSequence$$inlined$Sequence$3 found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.streams.jdk8.StreamsKt$asSequence$$inlined$Sequence$4 found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.text.jdk8.RegexExtensionsJDK8Kt found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0) Duplicate class kotlin.time.jdk8.DurationConversionsJDK8Kt found in modules kotlin-stdlib-1.8.20 (org.jetbrains.kotlin:kotlin-stdlib:1.8.20) and kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0)

在这里插入图片描述

解决方案

在build.gradle.kts文件末尾，添加以下配置

// 排除kotlin-stdlib-jdk8
configurations.implementation {
    exclude("org.jetbrains.kotlin", "kotlin-stdlib-jdk8")
}
