Re: [tycho-user] Building with Tycho offline

[Thanh Ha <thanh.ha@xxxxxxxxxxx>]

I was curious so I made a custom Tycho to add a print string to print the "prefix" and "repositoryLocation" at the beginning of this function [1]. What I noticed was on the working system the prefix is calculated to be "compositeContent" while on the system that is failing the prefix is calculated to be "content" as shown below.

How does the prefix get calculated? and why would it be calculated differently on different systems?



Working system:

Can you try on your failing machine after you deleted the local Maven repo ?

I tried this but it did not help. I even tried zipping up the local repo from the working machine and copying it over but that didn't seem to affect anything either.

Hi Everyone,

I ran into an issue trying to do an offline build with Tycho and was wondering if anyone ran into this before. Basically when I build on one system in offline mode I'm returned with "Repository system is offline and no local cache available for ..." (Snippet below) which as far as I can tell is a Tycho message.

I built this cache by first building normally to create the cache and then on my 2nd run I enabled Maven's --offline mode.

What's strange is that when I build on a different system following the same steps doing a normal build first to build the cache and then enabling offline mode, it works as expected. On both systems I'm building the same code and using the same version of JDK and Maven so I'm not sure what could be different between the 2 systems that would cause the error to appear in 1 but not the other.

Maybe there's some environment settings I can look at?


Thanks,


Thanh
