flutter 编译Android版本报错

[!] This is likely due to a known bug in Android Gradle Plugin (AGP) versions less than 8.x.x

这是java版本和Gradle版本兼容问题，需要统一设置。

1、先检测java版本是否21，如果不是请更新

2、setting.gradle更改

id "com.android.application" version "8.1.0" apply false
id "org.jetbrains.kotlin.android" version "1.8.22" apply false

改成

id "com.android.application" version '8.7.3' apply false
id "org.jetbrains.kotlin.android" version "2.0.21" apply false

3、gradle>wrapper>gradle-wrapper.properties 更改

distributionUrl=https://services.gradle.org/distributions/gradle-8.3-all.zip

改成

distributionUrl=https://services.gradle.org/distributions/gradle-8.9-all.zip

4、build.gradle(app) 更改

android {
    ···
    ndkVersion = flutter.ndkVersion

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_1_8
    }
    ···
}

改成

android {
    ···
    ndkVersion = "27.0.12077973"

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_21
        targetCompatibility = JavaVersion.VERSION_21
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_21
    }
    ···
}
