Gradle失败评估项目'：app'时发生问题

作者：刘美娥94662 | 2023-06-09 11:19

如何解决《Gradle失败评估项目'：app'时发生问题》经验，为你挑选了1个好方法。

我正在尝试为我的应用程序构建gradle，但是构建失败

我到处都在寻找与此问题有关的其他问题，但无法解决。另外，我尝试过更改gradle构建工具的版本，添加了不同的lib和一些其他无法解决问题的内容。

pubspec.yaml

项目级别build.gradle

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.3.0'
    }
}

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

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

应用程序级别build.gradle

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

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

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

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

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.app"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:multidex:1.0.3'
    implementation 'com.google.firebase:firebase-core:17.0.1'
    implementation 'com.google.firebase:firebase-firestore:20.2.0'

}

apply plugin: 'com.google.gms.google-services'

这似乎是由于Flutter样板指定了gradle插件的旧版本引起的。我仍然不清楚pubspec.yaml / lock中的Flutter软件包更新是否触发了该问题，我回滚了一些方法，但仍然存在。

由于某些原因，这会影响我的Windows 10系统，但不会影响我的Mac开发环境。据我所知，它们都是最新的（Flutter 1.7.8 + hotfix.4），并且在所有版本的相同版本上。因此，在下面的注释中使用了路径分隔符。

在android\gradle\wrapper\gradle-wrapper.propertiesFlutter样板中指定了gradle分布4.10.2，它支持的插件版本最高为3.3.2。但是，android\build.gradle仅取决于插件版本3.2.1（classpath 'com.android.tools.build:gradle:3.2.1'）。目前尚不清楚为什么Flutter样板内部不一致。

要解决，请更改com.android.tools.build:gradle:3.2.1=> com.android.tools.build:gradle:3.3.2，然后运行flutter clean并再次尝试构建。

根据gradle发行说明，该插件和gradle的当前（2019年7月）版本分别为3.4.2和5.1.1。我不知道Flutter是否正式支持此版本，尽管它似乎可以在我的项目中使用，而且干净的构建速度明显更快。发行说明涵盖了3.2.x => 3.3.x => 3.4.x的部分更改。

要升级到当前版本，请编辑android\gradle\wrapper\gradle-wrapper.properties源gradle 5.1.1，然后就可以将gradle插件升级到3.4.2。

gradle-wrapper.properties：

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

build.gradle：

classpath 'com.android.tools.build:gradle:3.4.2'

请注意，一旦使用gradle 5.1.1，您仍然可以将插件版本设置回3.2.1，以重现该问题。

我已经与Flutter团队讨论了一个问题，以尝试更好地理解这一点，如果他们有任何具体建议，将更新此答案。
