travis fails now - as far as I can see it's because the necessary version of guava (23) was updated in the swagger-codegen/pom.xml on the 17-01-2018, but travis seems to be using a snapshot of a few days earlier:

[INFO] Downloading from sonatype-snapshots: https://oss.sonatype.org/content/repositories/snapshots/io/swagger/swagger-codegen/3.0.0-SNAPSHOT/swagger-codegen-3.0.0-20180112.231844-20.pom

@ljgw the problem is that guava no longer in the dependency tree is.

I have compared the last released version (1.0.0-rc0) and the current SNAPSHOT version.

guava version 23.0 was provided by swagger-codegen (version 3.0.0-rc0). With the current 3.0.0-SNAPSHOT version, this is no longer the case.

See issue #5

You can rebase your change on top of PR #6, but as I wrote there this only solves the first errors mentionned in your Travis Build:

now that #7 is fixed, rebasing on master should help your change

[ljgw]

Thanks, @jmini. travis-ci will still fail because it cannot find ./mvnw, but at least everything compiles now on travis-ci.

[jmini]

Some code was pushed on master for mvnw(see #8)

[ljgw]

Some more code was pushed on master to fix the travis-ci build, and now it passes! I rebased on master and pushed.
