BPMN Fehler in Eclipse activiti

Question

Ich versuche, eine einfache Hello World-Anwendung mit Activiti Eclipse BPMN Designer 5.9 machen. Ich habe ein activiti-Projekt in Eclipse erstellt und das Diagramm check.bpmn zum Ordner src/main/resources und meine Dateien .java zu src/test/java und activiti.cfg.xml zum Ordner src/test/resources hinzugefügt. Die Anwendung soll nur die Warnung "Hello" auf der Konsole anzeigen, aber ich kann es anscheinend nicht dazu bringen. Unten, wenn alle Dateien, die ich verwende, um die Anwendung auszuführen. Ich weiß nicht, was ich vermisse. Ich habe Activiti Eclipse BPMN 2.0 Designer installiert.

UPDATE:

ich habe hinzugefügt JAR-Dateien

Fehler:

Answer 1

Der Fehler

Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \)

sagt Ihnen Ihr String ungültig ist.

private String filename = "C:\Users\User\workspace\Proj\src\main\resources\diagrams\Check.bpmn"; 

sollte

private String filename = "C:\\Users\\User etc..."; 

Answer 2

prüfen Maven Abhängigkeiten in Ihnen Projektstruktur entwertet werden. Überprüfen Sie, ob activiti-engine-{activiti-version}.jar verfügbar ist oder nicht.

Answer 3

Sie müssen das Projekt in Maven-Projekt konvertieren. Danach sehen Sie "Maven Dependencies" in Ihrem Projekt- und Klassenpfad.

Um zu konvertieren versuchen Sie rechts auf Projektname -> Kontextmenü -> Konfigurieren -> In Maven-Projekt konvertieren.
