CI doesn't detect gradle syntax errors

[ignasi35]

As reported in #74, #81, #72, ... some of the g8 template files use $ and templatecontrol messe them up breaking the g8 templating syntax.

The CI build in this repo doesn't detect this issue.

There is a gradle test, but it is configured as an allowed failure:
https://travis-ci.org/playframework/play-scala-seed.g8/builds/475599011

Looks like it was introduced here:
b28045a#diff-354f30a63fb0907d4ad57269548329e3R24

    # Current release of Gradle still does not supports Play 2.7.x releases
    # As soon as there is a release of Gradle that fixes that, we can then
    # remove this allowed failure.

@marcospereira it sounds like it should be safe to configure the 2.6.x branch to require this to pass, correct?

Looks like the underlying problem was fixed here: playframework/templatecontrol#85

Actually, this problem affects any use of sbt new, not just for Gradle users.

The problem is detected in the normal build, too, but does not cause the build to fail:
https://travis-ci.org/playframework/play-scala-seed.g8/jobs/475599012#L678

Falling back to file copy for /home/travis/build/playframework/play-scala-seed.g8/src/main/g8/build.gradle: File: /home/travis/build/playframework/play-scala-seed.g8/src/main/g8/build.gradle, 59:71: mismatched input '.' expecting LPAREN

The message is slightly different from what's reported by users, and looks like it's just a warning with fallback behavior. Maybe it depends on the sbt version used?

Gradle support has been dropped from this repo #119 therefore closing this issue.
However, meanwhile gradle does actually support Play 2.8, so if someone wants to it back here feel free to add a PR.
