EPG Import Plugin java.lang.ClassNotFoundException

[mwnswiss]

I suddenly got an exception with my xmltv.XMLTVImportPlugin which is not loading anymore.

The xmltv import property:
epg/epg_import_plugin=xmltv.XMLTVImportPlugin

the class files are as always in the folder xmltv/

Log shows:

I did not get that with 9.0.12.510 for sure and no other changes took place, but after digging around in the code I did not see any significant changes, the class loader seems to be untouched. So I would assume that it could relate to a java upgrade. I'm on build 1.8.0_121-b13 on a ubuntu 16.04 64bit installation. I recompiled the xmltv (https://github.com/yafraorg/xmltvplugin) but no success.

I'm a bit stuck, any help to further narrow it down would be appreciated.

I rolled back to 9.0.12 and it worked again, so it must be a change in the recent code which results into the loader issue of the EPG XMLTV plugin. It can't be related with the jvm updates, it must be with sagetv code changes.

Found it now. It was with commit https://github.com/google/sagetv/com...2994663dcec9f4 changing the classpath and replacing the ":.:". The path "." is needed for xmltv classloading.

I will do a change.

It might be better if the change involved putting the xmltv files in a jar and then adding that file the JARs directory, and/or updating it as a sagetv plugin. The "." is something that should not really be in the classpath (and was removed).

Any hint how I could load the class triggered through the property?

My guess is that if you add the xmltv files to a jar file, preserving the folder structure, and put that jar in the JARs directory, then it will just work.

It works, just did not include the xmltv/ directory in the jar, including the xmltv and having the setting still as xmltv.XMLTVImportPlugin it works now. I will update my repo for my xmltv importer https://github.com/yafraorg/xmltvplugin.
