run osgi webUI error

[jzybsy]

Hi, I download your SampleTap application on github,I change the Opendaylight SNAPSHOT of pom.xml in root directory.Using 1.4.6-SNAPSHOT instead of 1.4.2-SNAPSHOT.Because when I use 1.4.2-SNAPSHOT have this error Could not transfer artifact org.opendaylight.controller:commons.opendaylight:pom:1.4.2-SNAPSHOT from/to Spark repository:www.sparkjava.com and 'parent.relativePath' points at wrong local POM@line 4,column 11:Unknown host www.sparkjava.com

when I change it,I insert :mvn clean install ,I got BUILD SUCCESS but when I copy the jar in SampleTap-master/target under opendaylight plugin directory,I find another problem in OpenDaylight OSGi webUI

I guess the reason of this problem is the OpenDaylihgt's version not fit SampleTap,I use OpenDaylight code branch stable/hydrogen.But I can't find the latest version of hydrogen(the reason of not using helium is I can't find folder named plugins and I think it is not fit). Now I don't have any way to deal with it,please help me,thank you very much!
