无法应用插件[class'com.google.gms.googleservices.GoogleServicesPlugin'](对于输入字符串:“ +”)

我想用Firebase Cloud Messenging服务实施推送通知。我添加了:

ionic cordova plugin add cordova-plugin-fcm-with-dependecy-updated
npm install @ionic-native/fcm

app.component.ts中:

import { FCM } from '@ionic-native/fcm/ngx';

// ...

constructor(private fcm: FCM)

// ...

this.fcm.getToken().then(token => {
    console.log('Token :', token);
});

这使我在台式机中出现错误,因为Cordova不可用,没关系。

但是,当我想像往常一样在android上进行测试时,我会做出: ionic cordova run android --device

这给了我一个错误:

FAILURE: Build failed with an exception.

我正在与:

Ionic:

   ionic (Ionic CLI)             : 4.12.0 (C:\Users\username\AppData\Roaming\npm\node_modules\ionic)
   Ionic Framework               : @ionic/angular 4.1.1

   @angular-devkit/schematics    : 7.2.4
   @angular/cli                  : 7.3.6
   @ionic/angular-toolkit        : 1.4.0

Cordova:

   cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms     : android 7.1.4, ios 4.5.5
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 3.1.2, (and 8 other plugins)

   npm               : 6.9.0
   OS                : Windows 10

这是\ platforms \ android \ cordova-plugin-fcm-with-dependency-updated \ billingtests-FCMPlugin.gradle内容:

buildscript {
    repositories {
        mavenCentral()
        jcenter()
        mavenLocal()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.+'
        classpath 'com.google.gms:google-services:3.1.+'
    }
}
repositories {
    mavenCentral()
    jcenter()
}
dependencies {
    compile 'com.google.firebase:firebase-core:10.+'
}
// apply plugin: 'com.google.gms.google-services'
// class must be used instead of id(string) to be able to apply plugin from non-root gradle file
apply plugin: com.google.gms.googleservices.GoogleServicesPlugin

我遇到了完全相同的问题,终于能够通过一些猜测来解决此链接中的信息: cordova-android-play-services-gradle-release

这涉及添加一个特殊的插件来尝试设置所需的播放服务版本号。这个特殊的设置对我有用:

cordova plugin add cordova-android-play-services-gradle-release --variable PLAY_SERVICES_VERSION=16+

基本上,这似乎只是在 config.xml 中自动添加版本号:

<plugin name="cordova-android-play-services-gradle-release" spec="^2.1.0">
    <variable name="PLAY_SERVICES_VERSION" value="16+" />
</plugin>

也许您的情况需要一个不同的版本号,或者可能会因为使用Ionic 4并尝试添加推插件而有所不同。无论哪种方式,我都相信答案就在这种情况下。

*注意:这与插件 cordova-plugin-firebase

结合使用

我遇到了同样的问题,这是因为我错过了 com.google.gms:google-services 依赖项。我这样做是因为我在 Flutter 中重新生成了 Android 文件:

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.1'
        classpath 'com.google.gms:google-services:4.3.8'
    }

请务必按照 set up documentation 中的说明进行操作。
