根因分析

build.gradle中Java和Kotlin的JVM目标版本不匹配，导致编译不兼容。

English

Mismatch between Java and Kotlin JVM target versions in build.gradle, causing compilation incompatibility.

官方文档

解决方案

  1. In build.gradle (app level), set both targets: android { compileOptions { sourceCompatibility JavaVersion.VERSION_11; targetCompatibility JavaVersion.VERSION_11 } kotlinOptions { jvmTarget = '11' } }
  2. If using Java 8, align both to 8: kotlinOptions { jvmTarget = '1.8' } and compileOptions { sourceCompatibility JavaVersion.VERSION_1_8; targetCompatibility JavaVersion.VERSION_1_8 }

无效尝试

常见但无效的做法:

  1. Only changing compileSdk version in build.gradle without adjusting Java/Kotlin targets 95% 失败

    compileSdk is separate from JVM target; does not resolve version mismatch error.

  2. Setting both Java and Kotlin targets to 1.6 (deprecated) in hope of backward compatibility 85% 失败

    AGP 8.0+ requires minimum Java 8; 1.6 is unsupported and causes other errors.
