missing kafka source and sink for flume 1.5.2 binary package

[十六夜涙]

Since the flume git repository already has kafka source and sink source 
code.there's no kafka jar file in the lib directory‍ of flume home ,wish could 
get the binary package via download link.I tried to build flume by myself but 
it occurs an error while building flume-ng-morphline-solr-sink.‍
it shows:
Caused by: org.sonatype.aether.transfer.ArtifactNotFoundException: Failure to 
find ua_parser:ua-parser:jar:1.3.0‍‍
