How to upload a JAR file of an add-on for cloud JIRA

[thilini perera]

When submitting an add-on to market place i noticed that for both server and cloud version the .jar file can be submitted.

The same .jar file can be used to test in server version

But when i try to upload the add-on as a jar file in cloud version, it does not accept it.

Hi I want to install my Jira plugin on Jira cloud. How can I do it ?

[Robert Massaioli _Atlassian_]

You cannot upload a JAR file to the Atlassian Marketplace to be installed in Cloud instances. Only Atlassian Connect add-ons can be installed on Atlassian Cloud instances; they use descriptor files.

See: connect.atlassian.com

Hi Robert, So if I choose to upload just the .jar file, the marketplace will not allow the cloud instances to install the plugin?

[Robert Massaioli _Atlassian_]

That is correct. .jar files are built using Plugins 2. Atlassian Connect add-ons on the other hand can be installed in Cloud.

@Robert Massaioli _Atlassian_  I've build a jira plugin and can I upload it in my jira cloud environment ? Is this feature available now?

No, the "apps" framework for Cloud is totally different to the Server/DC one.  This is not going to change.

You need to write a different type of App, one suitable for Cloud.

Hi @Nic Brough -Adaptavist- , please could you provide appropriate link we can follow to create Cloud suitable apps and how we can integrate that app with our JIRA cloud instance. Thank you!

Bear in mind that Cloud and Server are very different - you will probably be able to reuse some of the logic in your Server app, but the frameworks are so different, you won't be able to just "convert" - you should treat this as an entirely new app.

Given the end of life announcement for supporting server licenses, is there ANY plugin to app migration methodology or utility?

[Nic Brough -Adaptavist-]

No, you need to move to apps that provide the same functionality on Cloud.

Some apps can take data from their server version to their Cloud version, but that is entirely a function of the app, it's not something you can generically code for.

@thilini perera  has this been resolved?  If so, I'm wondering if you could mark it as answered for us.  Thx.
