Bug 465447

Description Alexander Nyßen 2015-04-24 14:07:54 EDT

gef4master generates reference documentation by retrieving pages from wiki.eclipse.org via mylyn wikitext. Without any change to the wiki structure, nor the way it is retrieved (the scripts and mylyn wikitext libraries within gef4.releng have not been touched for over a year), the build suddenly started to fail when retrieving wiki contents and continues to do so. 

In build https://hudson.eclipse.org/hudson/job/gef4-master/2311/ it still passed the common.doc bundle's doc generation but failed when doing so for graph.doc:

[INFO] o.h.m.e.h.MavenExecutionResultHandler - Build failed with exception(s)

Since build https://hudson.eclipse.org/hudson/job/gef4-master/2312/ it now already fails when extracting wiki contents for common.doc:

[INFO] o.h.m.e.h.MavenExecutionResultHandler - Build failed with exception(s)

There are no changes to the code base (and I do not see any related to the wiki either) between both builds.
