In the meantime, I had a look at the Travis YAML file for examples how there the compilation for 2.12 is happening. It appears that 1) there might be a typo, because the build profile is 2.112 instead of 2.12 (see https://github.com/apache/flink/blob/master/.travis.yml#L143) and there's also not a build profile for only 2.12, it always includes Hadoop
