Fehler beim Ausführen des Ziels org.codehaus.mojo: exec-maven-plugin: 1.5.0: java (default-cli) im Projekt nextrtc-signaling-serverrror

Question

Ich habe nextrtc-signaling-server getestet, der Open Source für Java ist. Aber ich begegnete Maven Problem zu erstellen. Ich hoffe, dass das gelöst ist.

Mein Konsolenprotokoll.

Ich habe diese Quelle bei "clean package exec: Java" (Maven Ziele)

gebaut

Was muss ich tun? Ich möchte es wirklich reparieren.

Answer 1

Sie können das nextrtc-signing-server-Projekt (https://github.com/mslosarz/nextrtc-signaling-server) mit dem Befehl unten erstellen.

mvn clean package 

Wenn es eine Hauptklasse (zum Beispiel MySampleApplication.java) in einem Projekt mit Paket (zB com.sample.my), dann können Sie ausführen, dass unter Befehl.

mvn exec:java -Dexec.mainClass="com.sample.my.MySampleApplication" 

Wenn Sie neue Anwendung entwickeln wollen „nextrtc-Signalisierungs-Server“ können Sie dann unter Maven Abhängigkeit in Ihrem Maven Projekt hinzufügen. Bitte beachten Sie https://nextrtc.org/archives/85
