Non-resolvable parent POM in tutorial project #8

Closed andrew-koster- closed 8 years ago

andrew-koster- commented 8 years ago

There appears to be a problem with the structure of the Maven projects, and I don't know these projects well enough to fix this structural problem.

I'm following the instructions in https://www.kurento.org/docs/current/tutorials/java/tutorial-3-one2many.html with the goal of setting up a basic media server.

I've created a new Ubuntu 14.04 machine for this purpose and cloned the sources just before the build, so everything is up to date.

I opened the POM files in question and everything looks fine to me, but I'm far from an expert at Maven or at Kurento. This IS a tutorial project, it seems to me that it should Just Work for someone who isn't familiar with this software. Isn't that the point?

There is no problem with the structure of the project. You had just checked out the development version of the tutorials, which depends on a SNAPSHOT artifact. Since dev artifacts are not published in maven central, you need to checkout a release version of the projects, or add our development repo. Please read more in this stackoverflow answer.

We've updated the documentation to check out a release version, so this doesn't happen to new users.
