Subject Re: Stop offline mode artifact version renumbering
Date Mon, 29 Jul 2013 14:04:32 GMT
The application in question has a java web app which sits between a
message broker service and a database.
There is a plugin that also uses jetty but tries to keep it's own local
copy in it's own lib subdirectory.
When I replace the version number in the parent pom of the main project it
fixes that jetty-start issue.
And if I want to build the plugin, I do the same to it's pom file.
So I'm fairly sure the 7.5.3 number is coming from the top level project
specifically as it's the only piece of software on the system where that
version string is defined.

I'm building on a RHEL6 based system, and I initially had to force an
install of maven and a bunch of dependencies from a fedora17 branch  onto
a test system since it wasn't in the EPEL repo.
I then used that machine to recompile all those rpms from sources to have
a RHEL6 native install.
Since I built, and where necessary patched all those packages myself, I
trust that none of them are calling for jetty-7.5.3, however I do know
that a couple other transitives were giving me trouble, and I added a
custom depmap to the project as well as defining a common local repo in
the build directory for the project to use.
Without the local repo defined all the sub-packages used their own local
repo and later subs couldn't find the earlier jars it needed as

One of the framework dependencies was attempting to call both
servlet-api-2.5 and servlet-api-3.0 which, and this is odd, but even
though nearly everything else depends on 3.0, it kept taking 2.5 instead.
And even when I had fixed the top level pom to specifically take 3.0 (as
jetty-8 needs 3.0, it would rename 2.5 to 3.0 and cause the app to fail.
I ended up removing tomcat6 entirely from the system and substituting a
later fedora rpm jboss-servlet-api-2.5 which rebundles the 2.5 apis and
rebuilt the package that kept trying to pull in the wrong version
(resteasy or spring framework) to use that instead of the earlier tomcat.

I was just hoping that maybe maven could use the local version numbers
without renumbering everything as a command line option, especially for my
environment where I can't have the maven going online and have to use the
packages that I built from sources due to security requirements.
