Errore del test case nel sonar

Sto cercando di ottenere un rapporto sonar per uno dei miei progetti.Errore del test case nel sonar

Ho eseguito mvn clean install

Running blah.blah.BlahTest1 
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.016 sec 
Running blah.blah.BlahTest2 
Tests run: 3, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.078 sec

Quando eseguo mvn sonar:sonar ottengo l'errore sotto.

Could not find the main class: null. Program will exit. 
Exception in thread "main" 
[ERROR] There are test failures.

Non so da dove cominciare a cercare. Ho provato a cercare in google non ho trovato nulla di simile al mio problema.

Per favore aiutami a capire quale può essere una possibile causa da cercare.

Grazie.

Vorrei iniziare con l'aggiornamento della versione plug-infallibile. L'ultimo è 2.18.1, quindi 2.4.3 è antico. Inoltre, assicurati di utilizzare Maven 3. – user944849

@ user944849: Non posso farci molto. Cambiare la versione sarebbe l'ultima risorsa. – NewUser

Aspetta, perché non puoi aggiornare la versione del plugin? Sicuramente questo sarebbe l'approccio più semplice a questo problema che potrebbe benissimo essere collegato a un bug in una versione specifica. – Makoto

Io non sono un esperto di Maven, anche se ma, ho implementazione in cui, durante il ciclo di vita Maven, eseguo alcuni dei JUnità per trovare la copertura del codice e il sonar, naturalmente. Sto attaccando il mio pom. Forse questo aiuta.
