Add GradleProjectConfigurator to support smart-import

[laeubi]

Fixes https://github.com/eclipse/buildship/issues/356

Context

Currently gradle projects are not detected when using smart import. This adds the necessary ProjectConfigurator to support importing gradle projects this way.

[laeubi]

Build complain about

Line does not match expected header line of '^ * Copyright (c) \d\d\d\d Gradle Inc.$'. [RegexpHeader]

but I do not have anything to do with Gradle Inc so why should they hold the copyright of my contributed file?

[laeubi]

@donat can you probably take a look at this? This will really improve user experience and preventing false positive detection in m2eclipse.

[donat]

Sorry for the late reply. We'll take a look shortly.

@laeubi Would you mind rebasing your PR and changing the copyright line to

Gradle Inc. and others

This seems to be the recommended way of leaving the Copyright with it's original creators.

Feel free to add specific copyright notices somewhere down in the file, this was done in the past too.

[laeubi]

Done.

[reinsch82]

@laeubi you'll need to rebase again shortly, we had to change our copyrights too to match the new rule. For some reason the PR would let it through thx for your help

[laeubi]

@reinsch82 I have adjusted the "marker files", also feel free to enhance this as needed afterwards, this is more a first start to make it work, but you as the gradel experts might have some ideas how to further improve that, I'm only a (seldom) gradle user so most of the time :-)

[donat]

Thank you for the contribution, @laeubi!

[jabby]

Thank you @laeubi

Great to see this integrated, will this be part of the next Eclipse Release (2023-06) or are there usually release in between?

[donat]

We're planning to do a release in the upcoming weeks, so you can expect your changes to appear in Eclipse 2023-06 by default.
