Log the version of JDK installed

[asarkar]

The output from the action doesn't mention the version of JDK installed, which would be very useful to see.

I too think that reporting (and verifying) the version installed would be generally useful. The simplest way to do this is to execute java -version. One can obviously do that as a step in the job itself, but it would probably be useful (and cheap enough) to do this implicitly in the action as a good logging practice, as the version information is often needs for diagnostic reasons (and the need is usually noticed after the fact, rather than as a planned thing).

Is it possible to implement this seemingly easy ticket instead of waiting for the Big Bang #98 that could take months or even years?

Hello everyone. Setup-java@v2 was released and it logs version of setup java. Please see migration guide from v1 to v2. If you have any concerns feel free to reopen the issue.

@dmitry-shibanov I migrated to v2 and it looks good. Thank you. Couple of comments:

1. Not a big deal, but having a default distribution would be nice.
2. v2 seems to be more verbose, especially the downloading JDK part. Not sure if I want to see the action setting up Java in my build logs. May be hide it unless verbose: true is set?

Hello @asarkar. Thank you for your response and feedback.

1. We're not planning to make distribution field default one based on ADR.
2. Yes, sure. Setup-java@v2 is more verbose. But I'm not sure, that we should hide this logs. If you have any concerns about it, you can create separate issue to discuss it deeper.

Opened #157 for verbosity.
