Hi Thomasy,

I've written a lot of Atlassian apps in the past, and in my experience, apps need to be built and compiled for at least the major version of the system you're going to plug it into.

That is, an app compiled for 6.x.x is not likely to work in 7.x.x and extremely unlikely to work on 5.x.x.

It is possible to create apps that span large ranges of versions, but it's difficult, far beyond me. And some major version releases are simply completely incompatible. It is not possible to write an app for Jira 6 and 7 at the same time for example. I seem to remember Confluence has a similar break at 2 -> 3, 3 -> 4, and 7 -> 8.

You need to build your app for Confluence 6 if you want it to work on that version. Unless you're doing something very clever and specific, it should work fine for all 6.x versions, and has a good chance of working on 7.x. But you'll need to branch and update it for 8, no question.

Hi @thomasy Jacky

I'm not a SW Dev, but I've seen happening due to the many dependencies/libraries/differences between Confluence 6.x and 8.x.

Even a small version update can break a plugin when Atlassian introduces new changes.

Something that works in 8.x doesn't mean it will work in a previous, really old EOL version.

Hope that helps!

Regards

thomasy Jacky

but this plugin codes are base on 5.x version ，i just add some jars ，use the original pom.xml ,i just import other depencies ,it doesn't make a jar ,so it real matters with me!!!
