项目环境配置 #

• IDE: Android Studio Arctic Fox 稳定版 | Patch 3
• Java JDK 版本：11
• Kotlin 版本：1.5.30
• Jetpack Compose 版本：1.0.3
• Android Gradle 插件版本：7.0.2
• Gradle Wrapper 版本：7.0.2
• JaCoCo 版本：0.8.7

相关build.gradle配置 #

jacoco {
  toolVersion = "0.8.7"
}

android {
  ...
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
  kotlinOptions {
    jvmTarget = "1.8"
  }
}

buildTypes {
  debug {
    testCoverageEnabled true
  }
}

根因分析 #

该问题是Android Gradle Plugin 7.0+开启测试覆盖率（testCoverageEnabled true）后，和Jetpack Compose的构建流程冲突导致的：AGP 7.0+默认内置的JaCoCo版本和手动指定的0.8.7版本不匹配，Compose的字节码插桩流程会打断JaCoCo的插桩，最终导致运行时缺失JaCoCo的Offline类。

解决方案 #

方案1：调试阶段临时关闭测试覆盖率 #

如果当前不需要跑覆盖率统计，直接修改debug构建类型的配置：

buildTypes {
  debug {
    testCoverageEnabled false
  }
}

修改后重新构建即可解决启动崩溃问题。

方案2：强制指定统一JaCoCo版本 #

在app模块的build.gradle中添加JaCoCo运行时依赖，统一版本：

dependencies {
  implementation "org.jacoco:org.jacoco.agent:0.8.7:runtime"
  androidTestImplementation "org.jacoco:org.jacoco.agent:0.8.7:runtime"
}

多模块项目需要在所有开启了覆盖率的模块都添加该依赖。

方案3：升级AGP到7.1.0及以上版本 #

该版本官方已经修复了Compose和JaCoCo插桩的冲突问题，升级后保持原配置即可正常使用。
