How to start a single deployment upon successful completion of the Travis build?

Question

I am launching Travis CI using the Python version matrix, but I want to complete the release actions only after all of them are completed, obviously.

How can i do this? Expand actions seem to be performed for each substring.

Answer 1

This seems to be impossible at the moment, and there is a bug tracking it: https://github.com/travis-ci/travis-ci/issues/929

Update

Travis disables commenting on this issue, which is really bad. I assume that now you can only change them to open it again. Use social pressure, works against closed business models !;)

Also, if you are aware of some competitors that allow this, mention it! ... in the same tweet.

Answer 2

This is possible using the bash and Travis built-in variables. For a JavaScript / Node repository that will be:

dist: trusty language: node_js node_js: - '8' - '7' install: ... script: ... after_success: - 'if [ "${TRAVIS_NODE_VERSION}" = "8" ]; then cat ./coverage/lcov.info | coveralls ; fi' - 'if [ "${TRAVIS_NODE_VERSION}" = "8" ]; then firebase deploy --token $FIREBASE_TOKEN --non-interactive ; fi' 

Other built-in variables:

• TRAVIS_DART_VERSION
• TRAVIS_GO_VERSION
• TRAVIS_HAXE_VERSION
• TRAVIS_JDK_VERSION
• TRAVIS_JULIA_VERSION
• TRAVIS_NODE_VERSION
• TRAVIS_OTP_RELEASE
• TRAVIS_PERL_VERSION
• TRAVIS_PHP_VERSION
• TRAVIS_PYTHON_VERSION
• TRAVIS_R_VERSION
• TRAVIS_RUBY_VERSION
• TRAVIS_RUST_VERSION
• TRAVIS_SCALA_VERSION
