• make build - The build was successful.

• move2kube translate -s srcfolder - Tested with a simple ruby application and move2kube was able to detect it successfully. (Adding the screen shot below for reference)

@ashokponkumar I don't exactly understand why this build failed. There are no logs for the failure in details. Can you give me any inputs on this ?

You can check it out in https://travis-ci.com/github/konveyor/move2kube/builds/189306775. It is essentially failing because make test-style is failing. make test-style is failing because of missing license headers.

If you can add the license headers to the files you added, and did a make test-style, and if it succeeds, the build will succeed.

Thanks @ashokponkumar. Fixed it. Also, I think we can make test-style as part of build script. We can fail the local build if make-test fails. What's your opinion on this ?
