升级Gradle后Android Studio编译错误：Java与Kotlin JVM版本不匹配

升级Gradle版本后应用编译失败，已将项目Java版本改为17，且在Android Studio中修改了Gradle的Java版本，但问题仍未解决。

错误日志 #

Execution failed for task ':stripe_android:compileDebugKotlin'.
> 'compileDebugJavaWithJavac' task (current target is 1.8) and 'compileDebugKotlin' 
task (current target is 17) jvm target compatibility should be set to the same Java 
version.

当前app/build.gradle配置 #

plugins {
    id "com.android.application"
    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
}

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

android {
    namespace "com.roam1.esim"
    compileSdkVersion flutter.compileSdkVersion
    ndkVersion flutter.ndkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }

    kotlinOptions {
        jvmTarget = '17'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: 配置唯一的应用ID
        applicationId "com.example.sim"
        minSdkVersion 21
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    buildTypes {
        release {
            // 使用debug签名配置以便`flutter run --release`正常运行
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation 'com.facebook.android:facebook-android-sdk:latest.release'
    implementation platform('com.google.firebase:firebase-bom:32.4.0')
    implementation 'com.google.firebase:firebase-analytics-ktx'
}

错误根源是stripe_android第三方模块的编译目标版本还是1.8，和项目设置的17不匹配。你只配置了主app模块的版本，没覆盖到依赖模块，按以下方法解决：

方法1：统一所有模块编译版本 #

在项目根目录的build.gradle（非app子目录下的文件）中添加以下配置，强制所有子模块（包括第三方依赖）使用相同的Java和Kotlin版本：

subprojects {
    afterEvaluate { project ->
        if (project.hasProperty('android')) {
            project.android {
                compileOptions {
                    sourceCompatibility JavaVersion.VERSION_17
                    targetCompatibility JavaVersion.VERSION_17
                }
                kotlinOptions {
                    jvmTarget = '17'
                }
            }
        }
    }
}

方法2：单独配置stripe_android模块 #

如果不想影响其他模块，可在app目录的build.gradle中单独给stripe_android设置版本：

project(':stripe_android').afterEvaluate {
    android {
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_17
            targetCompatibility JavaVersion.VERSION_17
        }
        kotlinOptions {
            jvmTarget = '17'
        }
    }
}

额外检查项 #

1. 打开local.properties文件，确认org.gradle.java.home指向Java 17的安装路径，示例：

org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home

2. 执行File -> Invalidate Caches... -> Invalidate and Restart清理缓存后重新编译。
