我在启动应用程序NullPointerException时调用org.zkoss.less.ZKLessServlet.initLessResource时ServletContext.getResourcePaths(LessResourcePath) LessResourcePath，其中SEVERE: Servlet /IPSMWeb threw load() exception java.lang.NullPointerException at org.zkoss.less.ZKLessServlet.initLessResource(ZKLessServlet.java:121) at org.zkoss.less.ZKLessServlet.init(ZKLessServlet.java:90) at org.apache.catalina.core.StandardWrapper.initServlet(StandardWrapper.java:1190) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1103) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:1010) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4957) at org.apache.catalina.core.StandardContext$3.call(StandardContext.java:5284) at org.apache.catalina.core.StandardContext$3.call(StandardContext.java:5279) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619)是包含较少文件的路径。如何纠正这个问题？

错误的完整堆栈跟踪是：

调用ServletContext时的org.zkoss.less.ZKLessServlet.initLessResource中的java.lang.NullPointerException＃getResourcePaths（）
