It was working ok a few days ago, but recently the build started to fail. Anyone is having the same problem? What could it be?

[ricrempel]

Same problem here, all of a sudden. Have already tried cordova clean, manually cleaning gradle cache, removing and re-adding platform, starting project from scratch...

Commenting out app-FCMPlugin.gradle' line: 20 will have the app build, but then the plugin doesn't work well -- couldn't use FCMPlugin.getToken() for instance.

[chrisjpalmer]

I can confirm I am having the same issue. Did the same thing... wiped out the line 20 then plugin stops working => I debugged the code where the token is retrieved and an exception occurs.

But I seriously don't understand any of this gradle stuff. If some genius could come a long and fix it, that would be awesome.

[chrisjpalmer]

Here's a dirty hack to get it working. I have no idea about the long term fix however:

go to platforms/android/cordova-plugin-fcm and open up the gradle file inside. Make it look like this:

go to platforms/android/build.gradle Find the lines of code which have

And add the following lines around them (above and below)

Have your project open in android studio and go Tools > Android > SYnc Project with Gradle Files.

Build and it should work

[chrisjpalmer]

Basically I came across this solution by going back to basics according to the documentation.

Same issue here. It was working the last time I build but now it give me an error

same issue here... any stable fix?

[luigi37]

Chris Workaround does work.

I copy and paste the text to help others avoiding typos:

go to platforms/android/cordova-plugin-fcm and open up the gradle file inside.

Change the file from:

android {
    defaultConfig {
                multiDexEnabled true
    }
}

buildscript {
    repositories {
            jcenter()
                        maven { url 'https://maven.google.com' }
        }
    dependencies {
        classpath 'com.android.tools.build:gradle:+'
        classpath 'com.google.gms:google-services:3.1.1'
    }
}
// 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
ext.postBuildExtras = {
    apply plugin: com.google.gms.googleservices.GoogleServicesPlugin
}

To:

android {
    defaultConfig {
                multiDexEnabled true
    }
}

//buildscript {
//  repositories {
//            jcenter()
//                      maven { url 'https://maven.google.com' }
//        }
//    dependencies {
//        classpath 'com.android.tools.build:gradle:+'
//        classpath 'com.google.gms:google-services:3.1.1'
//    }
//}
// 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
//ext.postBuildExtras = {
//    apply plugin: com.google.gms.googleservices.GoogleServicesPlugin
//}

edit file platforms/android/build.gradle

change this:

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
    debugCompile(project(path: "CordovaLib", configuration: "debug"))
    releaseCompile(project(path: "CordovaLib", configuration: "release"))
    compile "com.google.firebase:firebase-core:11.4.2"
    compile "com.google.firebase:firebase-messaging:11.4.2"
    compile "com.android.support:support-v4:24.1.1+"
    // SUB-PROJECT DEPENDENCIES END
}

to this:

buildscript {
    dependencies {
    classpath 'com.google.gms:google-services:3.1.1'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
    debugCompile(project(path: "CordovaLib", configuration: "debug"))
    releaseCompile(project(path: "CordovaLib", configuration: "release"))
    compile "com.google.firebase:firebase-core:11.4.2"
    compile "com.google.firebase:firebase-messaging:11.4.2"
    compile "com.android.support:support-v4:24.1.1+"
    // SUB-PROJECT DEPENDENCIES END
}

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

[Maistho]

Any idea on how to convert this into a patch? Afaik it's not possible to modify build.gradle directly from a plugin, so is it possible to still only use the plugins gradle-file?

[luigi37]

no clue sorry :-(

[wdarking]

This issue may be related to Google's update on support package:

Google released the new version 28.0.0-alpha1 of com.android.support:support-v4 which is adding 2 new attributes(android:fontVariationSettings and android:ttcIndex). Some of the plugins are using the latest android-support libraries which results in unwanted incompatibilities.

source: https://stackoverflow.com/a/49200782/4687714

I've managed to solve my build problems using this workaround:

cordova platform rm android cordova platform add android

Option 2: Add next code snippet in build.gradle under platforms/android

configurations.all {
    resolutionStrategy.force 'com.android.support:support-v4:27.1.0'
}

Isn't a stable fix though

[Maistho]

@wdarking Cool, I've done a similar thing but still had some issues with multidex not being applied properly. Maybe I need to take a better look at that.

I guess that all plugins probably should do something like what they've done in cordova-plugin-googlemaps in order to properly support the correct android-support version. (Same with play services as well)
