Recently wrote a Maven Netbeans program that writes to firebase. It all works perfectly when I run it in the Netbeans IDE but when I build it and try to run it I get this error:
C:\Users\TOM\.m2\repository\com\FUJCode\climate2.0\1.0-SNAPSHOT>java -jar climate2.0-1.0-SNAPSHOT.jar
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/firebase/FirebaseOptions$Builder
at Climate.main(Climate.java:94)
Caused by: java.lang.ClassNotFoundException:
com.google.firebase.FirebaseOptions$Builder
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
... 1 more
I'm not sure why this is happening.
My code links to a json file here:
serviceAccount = new FileInputStream("serviceAccountKey.json");
FirebaseOptions options = new FirebaseOptions.Builder()
.setCredential(FirebaseCredentials.fromCertificate(serviceAccount))
.setDatabaseUrl("https://controller-39c7e.firebaseio.com/")
.build();
FirebaseApp.initializeApp(options);
} catch (FileNotFoundException ex) {
Logger.getLogger(Climate.class.getName()).log(Level.SEVERE, null, ex);
} finally {
try {
serviceAccount.close();
} catch (IOException ex) {
Logger.getLogger(Climate.class.getName()).log(Level.SEVERE, null, ex);
}
}
And I put the file itself here:
However I don't think this is the problem, I have added the dependencies in netbeans and like I said it runs in the IDE. Any help will be much appreciated.

Here is the pom.xml
