Martin Malina commented on JBIDE-17536:
---------------------------------------

I'm sorry, I still don't quite understand the difference between composite and aggregate. Is it that composite just points to the various components' update sites, whereas aggregate copies them into one place?
Thanks for offering http://download.jboss.org/jbosstools/updates/nightly/core/4.2.luna/ , but that's not what I want ;)  I just want to install nightly master, as offered here: http://tools.jboss.org/downloads/overview.html
We don't even offer 4.2.luna nightly from the web.

My point is: I just want to install the nightly master build that is listed on our web. And that fails sometimes. We might come to the conclusion that it's very rare and does not need solving. But using other update sites is not a solution (unless they offer master nightly and are listed on our web).

> When you install JBT nightly from http://download.jboss.org/jbosstools/updates/nightly/core/master/ into Eclipse and during the build, a new nightly build replaces the old one, you can get a failure like this:
> {code}http://download.jboss.org/jbosstools/updates/nightly/core/master/features/org.jboss.tools.wtp.runtimes.tomcat.feature_1.1.0.Beta3-v20140603-0027-B526.jar cannot be found{code}
> This is because during your install, the old jars were replaced with the new jars, i.e. different filenames.
> I'm not sure if it's something we really need to fix, it's open for discussion. But it happened to me yesterday and it wasn't the first time, so I'm throwing it on the table.
> Nick offered this alternative:
> install from a specific build folder instead of the "latest nightly"
> http://download.jboss.org/jbosstools/builds/nightly/core/master/2014-06-04_06-40-59-B8878/all/repo/
> http://download.jboss.org/jbosstools/builds/nightly/core/master/2014-06-04_09-46-40-B8879/all/repo/
> But obviously that's just a workaround, not a real solution.
> One way this could be achieved is this: plugins/ and features/ would contain jars from both the latest and previous builds. This way if you start installing (latest=build N) and in the middle of your installation there is a new build (N+1), there would still be jars for both N and N+1 builds.
