activiti 发布服务报空指针异常

Question

public void test2() throws FileNotFoundException{
//        InputStream inputStreambpmn = 
//                DeployeProcess.class.getClassLoader().getResourceAsStream("c");
//        InputStream inputStreampng = 
//                DeployeProcess.class.getClassLoader().getResourceAsStream("diagrams/leave-demo/God Of Learning.png");
//                processEngine.getRepositoryService().createDeployment().addInputStream("addInputStream", inputStreambpmn).
//                addInputStream("inputStreampng", inputStreampng).deploy();
        String bpmn = "resources/diagrams/leave-demo/God Of Learning.bpmn";
        String png = "resources/diagrams/leave-demo/God Of Learning.png";
        FileInputStream inputStreamBpmn = new FileInputStream(bpmn);
        FileInputStream inputStreamPng = new FileInputStream(png);
        Deployment deployment = processEngine.getRepositoryService().
                createDeployment().addInputStream("God Of Learning.bpmn", inputStreamBpmn).
        addInputStream("God Of Learning.png", inputStreamPng).deploy();
        System.out.println(deployment.getId());
    }

   上面的代码再部署的时候报空指针异常,为什么?
