如何解决添加应用插件时出错:'com.google.gms.google-services'
我正在尝试将 Firebase 与 Flutter 项目联系起来,我按照 firebase 指南中的描述做了所有的事情。但是当我将 apply plugin: 'com.google.gms.google-services'
添加到 android/app/build.gradle
时,控制台中出现此错误:
FAILURE: Build Failed with an exception.
* Where:
Build file 'C:\Users\yassine\AndroidStudioProjects\chat\android\app\build.gradle'
line: 25
* What went wrong:
A problem occurred evaluating project ':app'.
> com.google.common.util.concurrent.ExecutionError: java.lang.classFormatError: Illegal UTF8 string in constant pool in
class file com/google/gms/googleservices/GoogleServicesPlugin$PluginType
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
这是我的android/app/build.gradle
:
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def FlutterRoot = localProperties.getProperty('Flutter.sdk')
if (FlutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with Flutter.sdk in the local.properties file.")
}
def FlutterVersionCode = localProperties.getProperty('Flutter.versionCode')
if (FlutterVersionCode == null) {
FlutterVersionCode = '1'
}
def FlutterVersionName = localProperties.getProperty('Flutter.versionName')
if (FlutterVersionName == null) {
FlutterVersionName = '1.0'
}
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'kotlin-android'
apply from: "$FlutterRoot/packages/Flutter_tools/gradle/Flutter.gradle"
android {
compileSdkVersion 30
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
defaultConfig {
// Todo: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "userapp.chat"
minSdkVersion 23
targetSdkVersion 30
versionCode FlutterVersionCode.toInteger()
versionName FlutterVersionName
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 {
implementation platform('com.google.firebase:firebase-bom:28.3.0')
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.google.firebase:firebase-analytics'
implementation 'com.android.support:multidex:1.0.3'
}
这是android/build.gradle
:
buildscript {
ext.kotlin_version = '1.3.72'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.google.gms:google-services:4.3.8'
classpath 'com.android.tools.build:gradle:4.1.3'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
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
}
解决方法
显然文件中没有错误。请尝试以下操作:
运行命令:
flutter clean
然后,运行:
flutter pub get
执行项目。
