Gradle不断重新下载android sdk资源

Question

我正在使用在 Ubuntu 上运行的 Visual Studio Code for Android Dev (18)

gradle version: 7.4.2
java jre: 11 and 8
I have downloaded Android SDK with:
    "platforms;android-29"
    "platforma;android-31"
    "build-tools;29.0.0"

每次我发出命令：

./gradlew assembleRelease

我得到：

重新下载以下内容：平台工具、工具、模拟器和 patcher/v4

如何阻止 gradle 重新下载现有文件

我的构建.gradle

./gradlew assembleRelease

其他构建.gradle：

buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.2"
    }
}


allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter()
    }
}

gradle-wrapper.properties：

plugins {
    id 'com.android.application'
}

android {
    compileSdk 31
    defaultConfig {
        applicationId "xxx.xxx.xxx"
        minSdk 21
        targetSdk 31
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.4.0'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'io.socket:socket.io-client:1.0.0'
    implementation 'com.android.volley:volley:1.2.0'
}

Answer 1

我也曾因这个问题而苦苦挣扎，直到我向更有经验的 Android 开发人员寻求帮助。

解决方案很简单（至少在我的例子中），只需将 Gradle 指向正确的 SDK 目录即可。

我的local.properties：

sdk.dir=/usr/local/share/android-commandlinetools/cmdline-tools/latest

但相反，它应该是以下位置的更高级别目录local.properties：

sdk.dir=/usr/local/share/android-commandlinetools

我希望这可以帮助别人。
