Maven report generation breaks, if a new page was added with new attachments and references to it

[FromirDread]

Hi,
I guess I found an issue when a new page was created with new attachments and references.
Probably at this point, only attachments which were already uploaded are considered and new uploads are ignored.

Site structure:
X
--X1
----X1.1
----page.md
----attachments
pom.xml

In page.md
![some.txt](./attachments/some.png)

How to reproduce:
1.) Reference a new file ![some.txt](./attachments/some.png)
2.) Add suitable <attachment uri=""/> for your attachments folder
3.) Provide your new attachment in attachment folder

Job result:

Workaround:

1. Generate page.md without any image markup and execute job
2. Add image markup and execute job again

Hi @FromirDread

I used this plugin for myself a lot, but what you are describing never happened.

Please share your site.xml (or .yaml) and the content of page.md so I can verify the issue

[bsorrentino]

@FromirDread I've deployed the release 7.12-SNAPSHOT with a fix

Please take chance to test it and let me know

[bsorrentino]

fixed in release 7.12

[FromirDread]

Hi,
I unfortunaly I haven't found time to test it last days.
Do you know when it's published to maven central?
I would also like to test it, if it's also from functional point of view fine.

Probably the publication process is bit slow today.

[bsorrentino]

It is published confluence-reporting-maven-plugin-7.12

[FromirDread]

@bsorrentino my problem was fixed with 7.12. I would also like to highlight that your response time and community is super fast. Thank you very much for this effort!
