Stuart McCulloch commented on WAGON-407:
----------------------------------------
My analysis:
Looks like a shading issue in maven-wagon/wagon-providers/wagon-http:
https://git-wip-us.apache.org/repos/asf?p=maven-wagon.git;a=blob;f=wagon-providers/wagon-http/pom.xml;h=1fd61e34da435024062a566f6bd68410d98fdc67;hb=HEAD#l87
It doesn?t shade in commons-io, commons-lang, or jsoup; despite
wagon-http-shared switching from plexus-utils to commons-lang/io, and over to
jsoup as the HTML parser:

It might be less fragile to just exclude unwanted dependencies in the
wagon-http shade configuration, rather than have to keep the list of includes
in sync?
As to why the IT passes with M2 but fails with M3... wagon-http is included in
the distribution lib (uber jar for M2, separate jar for M3) so M2 is using an
older version of wagon that doesn?t suffer from the above issue.
(NOTE: adding commons-io, commons-lang, and jsoup jars to the M3 distribution
lib is a workaround for this issue)
