Trivadis IoT卡车模拟器Maven构建运行空指针异常求助

我正尝试运行开源IoT卡车模拟器，需对项目进行二次开发，修改路线点位、新增不同IoT设备以适配自身需求。我已下载项目压缩包，完成IntelliJ环境配置后尝试构建运行，但持续出现多个报错，出现频率最高的报错栈如下：

Exception in thread "main" java.lang.RuntimeException: Error running truck stream generator
at com.hortonworks.labutils.SensorEventsGenerator.generateTruckEventsStream(SensorEventsGenerator.java:43)
at com.hortonworks.solution.Lab.main(Lab.java:277)
Caused by: java.lang.NullPointerException
at java.base/java.util.Arrays.sort(Arrays.java:1249)
at com.hortonworks.simulator.impl.domain.transport.route.TruckRoutesParser.parseAllRoutes(TruckRoutesParser.java:77)
at com.hortonworks.simulator.impl.domain.transport.TruckConfiguration.parseRoutes(TruckConfiguration.java:62)
at com.hortonworks.simulator.impl.domain.transport.TruckConfiguration.initialize(TruckConfiguration.java:38)
at com.hortonworks.labutils.SensorEventsGenerator.generateTruckEventsStream(SensorEventsGenerator.java:25)
... 1 more

根据报错信息定位到Lab.java中getResource与getPath相关代码段：

sensorEventsParam.setNumberOfEvents(1000);
sensorEventsParam.setDelayBetweenEvents(delayBetweenEventsMs);
System.out.println(Lab.class.getResource("/" + "routes/neom").getPath());
sensorEventsParam.setRouteDirectory(Lab.class.getResource("/" + "routes/neom").getPath());
sensorEventsParam.setTruckSymbolSize(10000);
SensorEventsGenerator sensorEventsGenerator = new SensorEventsGenerator();
sensorEventsGenerator.generateTruckEventsStream(sensorEventsParam);

我推测问题来源于路径处理逻辑，因为sensorEventsGenerator.generateTruckEventsStream的报错指向getRouteDirectory方法，而该配置值来源于sensorEventsParam的setRouteDirectory方法赋值。求排查思路与解决方案。
