fix: enforce blank line after body declaration

[Shaolans]

What changed with this PR:

Fix #271

Example

// Input
public class JWTFilter extends GenericFilterBean {
    public static final String AUTHORIZATION_HEADER = "Authorization";

    private TokenProvider tokenProvider;
}
// Output
public class JWTFilter extends GenericFilterBean {

    public static final String AUTHORIZATION_HEADER = "Authorization";

    private TokenProvider tokenProvider;
}

However it should be noted that we can have this case:

// Input
public class MyClass {
    public void myMethod() {
        return new AnonymousClass() {
            int a;
        }
    }
}
// Output
public class MyClass {
    public void myMethod() {
        return new AnonymousClass() {

            int a;
        }
    }
}

Since inside the class this is also a classBodyDeclaration node.
I think we can probably make an exception on class body for anonymous class but I don't know if we should.

ping @Shaolans @clementdessoude
What's the state of this PR plz ?
It's opened since 4 months

[Shaolans]

It should be good to go but as I explained with this PR, when you now define an anonymous class it will enforce a blank line and I was wondering if we should keep it that way.

[pascalgrimaud]

ok, you're right @Shaolans
exception for anonymous class should be nice. Is it possible ?

[sanjayrawat1]

@Shaolans Is there any update on this PR, please. I would like to adopt prettier-java in my new project but because of this issue, I would not be able.

[Shaolans]

Hi,
Sorry I was quite busy these past few weeks.
I will try to do it this week or the next one.

[Shaolans]

It should be good to go.
@clementdessoude Can you merge and make a release since this bug was requested many times ?

[sanjayrawat1]

If @clementdessoude is not available can someone else merge this PR, please! Maybe @pascalgrimaud or @deepu105.

[pascalgrimaud]

I'll contact Clement today

[sanjayrawat1]

Thanks, @pascalgrimaud for merging this PR. I guess the team is waiting for other PRs (#384) to get merged, after that the new release will come out. Hoping for the new release coming out soon.

[pascalgrimaud]

@sanjayrawat1 : I don't forget you. I didn't manage to contact @clementdessoude about release process.
I'm waiting @Shaolans or @Hawkurane to merge this #384
If no answer, I'll trust you and merge it myself. Then, I'll try to do a new release.

[pascalgrimaud]

Just have some news about Clément. He told me he'll try to find time for reviewing the other PR and will do a new release during this week-end.
Is it fine for you @sanjayrawat1 ?

[sanjayrawat1]

@pascalgrimaud Yeah, it's fine. Thanks a lot!

[sanjayrawat1]

@pascalgrimaud can we have a release, please?

[pascalgrimaud]

@sanjayrawat1 : I'll try

[pascalgrimaud]

@sanjayrawat1 : just release v0.8.3 -> https://github.com/jhipster/prettier-java/releases/tag/v0.8.3
I'm waiting your feedbacks to tell me if it works well, like you wish

[sanjayrawat1]

@pascalgrimaud Yeah, it's working as expected. Thanks :)

[clementdessoude]

Thank you for taking care of the release @pascalgrimaud !
