在做solr的dataimport的定时任务时，启动时报了如下的错误，一直搞不明白，最后发现是引的包有问题（apache-solr-dataimportscheduler-1.0.jar）

08-Dec-2016 11:57:06.563 INFO [localhost-startStop-1] org.apache.jasper.servlet.TldScanner.scanJars At least one JAapache-solr-dataimportschedulerR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

解决方法时，换一个包，在网上找了一个大神重新编译的包，验证后是可以使用的。
