Build: relax jar-dependencies requirements (logstash-plugins#19)

Bundler is having issues (using bundle exec) with default gems :
`ruby -rbundler/setup -S rake vendor`

```
Gem::LoadError: You have already activated jar-dependencies 0.4.0, but
your Gemfile requires jar-dependencies 0.3.12. Prepending `bundle exec`
to your command may solve this.
```

Merge pull request logstash-plugins#1 from yaauie/initial-release

bump version to 10.0.0
