Travis-ci file for multi-module multi-language project - travis-ci

Question

Is there a way to setup travis-ci to build multiple projects in different languages ?
Lets say my repo is
AwesomeRepoThatDoestOneThingInDifferentLanguages
-cpp
-csharp
-python2
-python3
-java
-go
-ruby
-lua
-objectivec
Now, I wish to apply ci to this.
If I just add .travis.yml file to my python2 project, travis-ci complains that no .travis.yml found, since its looking for one at the root of the repo.
So, is there a way where I can put a .travis.yml at the top, which then further invokes the travis.yml in each of my sub-modules ?

Answer 1

I was able to find a way to actually do this. This is not complete yet since some of the jobs are still failing and I need to fix them individually, but overall the idea works just fine.
I am using travis ci's matrix way. Here is my .travis.yml
Thought this might help if someone else had the same question or scenario.
