Re: [platform-releng-dev] Problem migrating releng config to new Git set

[David M Williams <david_williams@xxxxxxxxxx>]

Questions such as this are best asked on
the cbi-dev list (The "common build" list) whereas this list
is specific to "building the platform". 

But, I'll give you a few hints, so your
next question on cbi-dev can be more specific. 

First, what ever your "automatic
build" does ... you probably want to do "by hand" a few
times, so you more easily learn what's going on. 

Second, you'd for sure not want to use
a "cvs" command to get something from Git. The typical pattern
is to check if repository (directory) exists locally and if not, clone
it (see 'git clone') . If it did already exist, from previous runs, you'd
want to do a "pull" to fetch everything new, and merge it into
your existing repository tree. (A 'git pull' does a 'git fetch' followed
by a 'get merge'). 

Thirds, the typical pattern, using Hudson
or similar, is to let Hudson do it for you. I has s "SCM" section
where you can specify your repo parameters, and have it clone or fetch
things on a schedule. So, by the time it get's to your build step, you'd
assume everything you need, is already there. 

I'm sure for any individual case, there's
a few dozen variations on the above themes, but once you get a little further
and need some more quick education, the cbi project is the place to get
help. 

Good luck,

Hi,
we recently migrated to Git and now we are having trouble
getting our build working again. The problem is that I don't know how to
tell the build script that the releng project root is a Git repo, and not
CVS or SVN. Here the output:

[start] [05:53:24] Started on 20140711 with these
options:
   -projectid modeling.emft.henshin
   -version 0.9.11
   -buildType N
   -buildTimestamp 201407110553
   -writableBuildRoot /opt/users/hudsonbuild/.hudson/jobs/cbi_henshin_nightly/workspace/build
   -thirdPartyJarsDir /opt/users/hudsonbuild/.hudson/jobs/cbi_henshin_nightly/workspace/build/3rdPartyJars
   -downloadsDir /opt/users/hudsonbuild/.hudson/jobs/cbi_henshin_nightly/workspace/build/downloads
   -buildDir /opt/users/hudsonbuild/.hudson/jobs/cbi_henshin_nightly/workspace/build/N-SNAPSHOT
   -projRelengRoot /gitroot/henshin/org.eclipse.emft.henshin.gitd
   -projRelengPath releng/nightly
   -buildAlias N-SNAPSHOT
   -forceContextQualifier
   -fetchTag HEAD

[start] Create build directory /opt/users/hudsonbuild/.hudson/jobs/cbi_henshin_nightly/workspace/build/N-SNAPSHOT

  cvs -d /gitroot/henshin/org.eclipse.emft.henshin.git -Q ex -r HEAD
-d org.eclipse.henshin.releng releng/nightly
cvs [export aborted]: cannot get working directory: No such file or directory


How can I specify that it is a Git repo?


Cheers,
Christian
