Running a script conditionally doesn't work in travis.yml, why?

Question

The following reasons do not allow building at all. When I try to check the file travis.yml, it complains that the line just above the if statement is missing a character -in column 3, but the error is related to the if statement below.

Do I need to move the if statement to a script?

# Deploy
after_success:
  - ./tools/docker-push-container.sh
  - if [ $TRAVIS_BRANCH == "master" && $TRAVIS_PULL_REQUEST == "false" ]; then
      ./.travis/success_message.sh
    fi

Answer 1

You make some assumptions about the YAML syntax that cause problems. If you “highlight” the YAML line by inserting the following lines into it, for example:

- The quick brown fox
  jumped over the
  lazy dog.

This is exactly the same as you wrote this:

- The quick brown fox jumped over the lazy dog.

This means that your shell fragment that you wrote as:

  - if [ $TRAVIS_BRANCH == "master" && $TRAVIS_PULL_REQUEST == "false" ]; then
      ./.travis/success_message.sh
    fi

It actually becomes:

if [ $TRAVIS_BRANCH == "master" && $TRAVIS_PULL_REQUEST == "false" ]; then ./.travis/success_message.sh fi

sh: -c: line 1: syntax error: unexpected end of file

; fi. :
