Missing SVN Update on materialized plugins [message #1132800]

Hello all,

I'm deciding to write on something that's happening on our builds long time ago but never managed to fix: Buckminster resolves some plugins through SVN (a convenien searchPath is defined in our RMAP). So far so good. However, next time we launch a build, Buckminster finds the plugin already materialised, but does not consider the fact that there may be new commits in SVN affecting that plugin. The Result: we get a build with an old version of the plugin.

Found several posts about this, but none clearly stated how to solve this (the advisorNode technique does not seem to work for us either)

https://bugs.eclipse.org/bugs/show_bug.cgi?id=286284
(Bucky Book does not document the above feature, AFAIK)

http://www.eclipse.org/forums/index.php?t=msg&th=202459&start=0&S=7ca5960ff6869b921d186b4c8ef28222

My workaround used to be deleting buckminster.output, but that makes the next build take much longer, as everything needs to be materialised again.

Now I created a script that executes "svn update" over plugins resolved through SVN.

cd %Workspace%\plugins
for /d /r %%i in (*com.opencanarias*) do @svn up %%i
cd %Workspace%\features
for /d /r %%i in (*com.opencanarias*) do @svn up %%i

Is there any way to tell bucky that it should update plugins resolved through svn before building?

I'm using the 4.2 bucky release

Thank you!
Víctor Roldán

We do exactly what you do (loop through and svn update) - we also do the same for git (loop through and git pull). I never found a way to make Bucky do this for you.

Mathew,

I see, so I'm not alone on this Razz

Hope someone from the bucky team can clarify this.

Thanks for your comments,
Víctor.

I guess you're using Jenkins or Hudson, right?
The auto update from svn/git/cvs could be done by the Jenkins job
configuration ("Source Code Management" section); this is
straightforward if you fetch from a single source repository...

does it take longer because a brand new svn checkout is performed, or
because the workspace needs to be materialized from scratch?

In the latter case, I've always thought that it is better to always
perform a brand new workspace materialization in a headless build... at
least that's what I saw in most examples (and it never gave me problems
in all my builds; on the contrary trying to do an incremental workspace
materialization always gave me troubles)... of course you can avoid
materializing the target platform itself over and over again, I was only
referring to materialization of projects in the workspace.

cheers
Lorenzo
