[FIXED] java.lang.NoSuchMethodError when initialising firebase through admin SDK Java

Issue

I am trying to connect to firestore through the firebase admin SDK. However, when I call:

 FirebaseOptions options = new FirebaseOptions.Builder()
            .setCredentials(GoogleCredentials.fromStream(serviceAccount))
            .build();
    
    FirebaseApp.initializeApp(options);

I get the following exception: java.lang.NoSuchMethodError: 'void com.google.common.base.Preconditions.checkArgument(boolean, java.lang.String, java.lang.Object)'

I only get this exception when running the program through the jar file, it runs fine when compiled through NetBeans. I read online and it seems to be an issue with versions of the firebase admin SDK, but I am not sure which version to use and have tried multiple versions with the same error.

Maybe it is an error with the way I am bundling my dependencies in the jar file?

This is my build.gradle file:

apply plugin: 'java'
apply plugin: 'jacoco'
apply plugin: 'application'


mainClassName = 'QMPAngola.Main'

repositories {
    jcenter()
}

dependencies {
    compile 'com.google.firebase:firebase-admin:5.9.0'
    testCompile 'junit:junit:4.12'
}

configurations.all {
    resolutionStrategy {
        force 'com.google.guava:guava:30.1.1-jre'
    }
}

jar {
    manifest {
        attributes "Main-Class": "QMPAngola.Main"
    }
    
    from { (configurations.runtime).collect {it.isDirectory() ? it : zipTree(it)} } 
   
}

This is the full stacktrace:

Solution

From my understanding com.google.firebase:firebase-admin is using guava as dependency.

From my understanding you override the transitive dependency to guava by

configurations.all {
    resolutionStrategy {
        force 'com.google.guava:guava:30.1.1-jre'
    }
}

with a incompatible version.

I'd say you should remove that block or is there any reason why you added it?
