for people interested in working on this relocation topic: 1. I just updated the relocation guide to add some details gathered from the current discussion [1]
2. I'll be at JChateau unconference [2] mid-march: if people want to join, we could probably work on this topic Regards, Hervé [1] https://maven.apache.org/guides/mini/guide-relocation.html [2] https://www.jchateau.org/ Le jeudi 20 février 2020, 08:54:53 CET Hervé BOUTEMY a écrit : > +1 > > probably will start by improving the documentation, because this is really > the current intent from what I can understand: a relocation pom only > provides relocation info only, no jar, no build info > > like https://repo.maven.apache.org/maven2/ant/ant/1.7.0/ that points to > https://repo.maven.apache.org/maven2/org/apache/ant/ant/1.7.0/ > > AFAIK, there is no modification expected on existing artifacts, just > relocation poms to create at old coordinates to point new coordinates = the > new canonical coordinates > > > then perhaps the way it is implemented can be improved: one issue I can see > (from a pure theoretical point of view, I didn't take time to make extensive > tests) is to define when you stop publishing relocation poms at old > coordinates, ie. starting with which version? > and how to be sure that the relocation is detected when resolving both old > coordinates and new coordinates that are both canonical coordinates? > > for example ant:ant:1.6.5 (= canonical coordinates for this release) and > org.apache.ant:ant:1.8.0 (= canonical coordinates for this release), given > there is no relocation pom published for ant:ant:1.8.0, only for > ant:ant:1.7.0 > > Regards, > > Hervé > > Le mercredi 19 février 2020, 16:48:38 CET Jonathan Valliere a écrit : > > Maybe we need to rework how this functionality works.
