> Recently I've opened a few jiras which suggested to use standard java classes
> instead of external libraries ( OOZIE-3463, OOZIE-3467). There is a tool
> which can find such technical depts: [maven modernizer
> plugin|https://github.com/gaul/modernizer-maven-plugin].
> The usage is quite simple:
> {noformat}
> $ mvn modernizer:modernizer

> There are several ways to use this plugin:
> # Add the plugin to the root pom and let developers manually use this
> plugin. It's the simplest solution, but it will be easy to forget it.
> # Add this to the precommit script similarly to findbugs and at least avoid
> to insert new code which uses old style API. Probably we will have the same
> problems like we have with findbugs, we will have lots of false positive
> warnings.
> # Turn the plugin on by default and fail the compilation if it finds any
> problem. I think this is too strict.
> If we choose option 2 or 3 we should probably specify an ignore list, I don't
> think for instance that we really want to change all the {{new Long(10)}}
> code to {{Long.valueOf(10)}}.
> By default this plugin checks the target java version (1.8 right now) but
> it's possible to specify 1.7 instead if we want to focus on those problems
> first. (It was not working for me without specifying the java version.)
