Problem installing Demo Flavor

[vmassol]

@Chaos234

and I don’t know why this happens because Index of /groups/public/org/xwiki/contrib/macro-jwplayer/2.1.8 exists at the mentioned URL

Actually it (= the XAR) doesn’t exist at that URL. What exists is a POM module, see Index of /groups/public/org/xwiki/contrib/macro-jwplayer/2.1.8

What you want is probably Index of /groups/public/org/xwiki/contrib/macro-jwplayer-ui/2.1.8

Thx
