What setup for build cache is require for bundle install

Hello,

I am a bit of a noob in terms of all things ruby, so I am looking for some help.

As part of the deployment of my blog site, which is using octopress as the engine, I run the command bundle install. This goes off and grabs a bunch of installations each time I build my blog. I figure I should be able to cache these files using the appveyor build cache, but I have no idea what folder they end up going into.

Any thoughts on which folder I should add to the build cache to speed up this installation process, and not have to download the files each time?

Thanks!

Gary

   I "think" i might have answered my own question :-)

   Using this:

   http://stackoverflow.com/questions/5107141/ruby-on-rails-where-to-g...

   Added the following commands to my build script:

     - cmd: gem env
     - cmd: bundle show rack
   

   Which resulted in this:

   https://ci.appveyor.com/project/GaryEwanPark/adnuguk-github-io/buil...

   So I have added this to my cache settings:

   cache:
     - C:/Ruby193/lib/ruby/gems/1.9.1
     - C:/Users/appveyor/.gem/ruby/1.9.1
   

   And just trying this out. Does this seem like a sensible approach?

   Thanks

   Hmmm, did I do something wrong? My build just failed:

   https://ci.appveyor.com/project/GaryEwanPark/adnuguk-github-io/buil...

   With the error:

   The system cannot find the path specified

   All I did was add this:

   https://github.com/adnuguk/adnuguk.github.io/commit/34b7370a096a9e2...

   It is like the caching was able to find the folder, even though the gem env command just told me that it was there.

   Any thoughts?

   Thanks!

   Ok, looks like I am getting "somewhere" with this.

   If I change from this:

   cache:
     - C:/Ruby193/lib/ruby/gems/1.9.1
     - C:/Users/appveyor/.gem/ruby/1.9.1
   

   To this:

   cache:
     - C:\Ruby193\lib\ruby\gems\1.9.1
   

   i.e. use backslashes, rather than forward slashes, then the build caching works.

   However, then the rest of the build stops working properly :-(

   Here is the output of the build when caching is enabled:

   https://ci.appveyor.com/project/GaryEwanPark/adnuguk-github-io/buil...

   And here is the output from a build straight after the last one, with caching disabled:

   https://ci.appveyor.com/project/GaryEwanPark/adnuguk-github-io/buil...

   As you can see it is the rake generate step where things start to go wrong. I honestly have no idea why this is happening, or what effect the build caching is having on the process. Can anyone help?

   Thanks!

   Gary

   Maybe cache already contains some invalid data.

   I've just reset the cache for this project - give it another try with cache enabled.

   Re-running build now, will keep you posted.

   Thanks!

   Hello Feodor,

   Sorry to report that the same problem occured:

   https://ci.appveyor.com/project/GaryEwanPark/adnuguk-github-io/buil...

   Do you know if the folder that I am caching is all that is required? I am a complete noob in Ruby, and I don't know if there is other stuff that I need to cache or not.

   Thanks

   Gary

   That's interesting. Maybe there is some issue with file timestamps restored from cache.
   Btw, this is how it works in Travis: http://docs.travis-ci.com/user/caching/

   Another idea! Many gems put their bash or CMD scripts into bin folder to make tooling work from command line, for example jekyll.

   I think you should also try caching C:\Ruby193\bin folder in addition to that one.

   I cleared your cache one more time.

    You sir, are a genius!

    Build now working:

    https://ci.appveyor.com/project/GaryEwanPark/adnuguk-github-io

    with this:

    cache:
      - C:\Ruby193\lib\ruby\gems\1.9.1
      - C:\Ruby193\bin
    

    as cache settings.

    Thanks again!

    The above has taken my build times from 5 min 37 sec to 2 min 28 sec

    Awesome! This definitely should go to the docs!

    Thanks for the update!

    How does the documentation work here at AppVeyor, do you accept any community contributions?

    Website is in private repo right now, but we're going to make it public.

    If you want to help with content (any, not only help) - this would be fantastic help!

    Happy to help out, where and when I can :-)

    Perhaps a separate Issues list, or at least categorized issues, with tasks that can be cherry picked and raised as PR's into the documentation repo?
