Without looking at the JIRA issue, the 'specification' of what 'A;B' should do is explained here: http://ant.apache.org/ivy/history/latest-milestone/ivyfile/dependency.html
without a defaultconfmapping set the following should be equivalent: A;B = A->A;B->B Maarten Van: Gintautas Grigelionis <g.grigelio...@gmail.com> Aan: Ant Developers List <dev@ant.apache.org> Verzonden: vrijdag 2 februari 9:55 2018 Onderwerp: IVY-1282 It seems that there still are problems with conf mappings containing whitespace around semicolon separator.

I cannot find a specification, though, what should happen when defaultconfmapping is not set or when conf is "A;B": an exception or semicolon interpreted as comma? Gintas
