谷歌地图插件科尔多瓦不加载getMap（）

Question

Everything worked before. But suddenly it's showing white screen and throwing this below error.

getMap is not defined

buildscript {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
    dependencies {
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
    //This replaces project.properties w.r.t. build settings
    project.ext {
      defaultBuildToolsVersion="'26.0.2'" //String
      defaultMinSdkVersion=19 //Integer - Minimum requirement is Android 4.4
      defaultTargetSdkVersion=26 //Integer - We ALWAYS target the latest by default
      defaultCompileSdkVersion=26 //Integer - We ALWAYS compile with the latest by default
    }
}

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

The dependency section of platform/android/app/build.gradle is probably like this:

dependencies {
    implementation fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
    implementation(project(path: ":CordovaLib"))
    compile "com.google.android.gms:play-services-maps:12.0.0"
    compile "com.google.android.gms:play-services-location:12.0.0"
    compile "com.android.support:support-core-utils:24.1.0"
    compile "com.google.gms:google-services:+"
    compile "com.google.android.gms:play-services-tagmanager:+"
    compile "com.google.firebase:firebase-core:+"
    compile "com.google.firebase:firebase-messaging:+"
    compile "com.google.firebase:firebase-crash:+"
    compile "com.google.firebase:firebase-config:+"
    // SUB-PROJECT DEPENDENCIES END
}

The problem is some plugin specifies + , but the maps plugin specifies 12.0.0 (or maybe other versions)

The version number + is very danger keyword. The gradle use the latest version at the build time when you specified + , but it does not work sometimes. That's why the maps plugin specifies particular version, but you can specify the version with --variable .

You need to modify the build.grale file. Specify the same version of all dependencies that use Google Play Services SDK.

For example:

dependencies {
    implementation fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
    implementation(project(path: ":CordovaLib"))
    compile "com.google.android.gms:play-services-maps:12.0.1"
    compile "com.google.android.gms:play-services-location:12.0.1"
    compile "com.android.support:support-core-utils:24.1.0"
    compile "com.google.android.gms:play-services-tagmanager:12.0.1"
    compile "com.google.firebase:firebase-core:12.0.1"
    compile "com.google.firebase:firebase-messaging:12.0.1"
    compile "com.google.firebase:firebase-crash:12.0.1"
    compile "com.google.firebase:firebase-config:12.0.1"
    // SUB-PROJECT DEPENDENCIES END
}

By the way com.google.gms:google-services:+ installs all packages. This increases apk file size. And it causes troubles. I recommend to remove it.

update: Also classpath 'com.google.gms:google-services:3.0.0' should be removed because of the same reason.
