Reuse Jira Components in my own plugin code

[eXtensi Admin]

I'm building a new plugin and I'd like to reuse some of the existing Jira functionality by importing some dependencies into my plugin.

For example

<dependency>com.atlassian.jira.jira-issue-nav-components:query</dependency>

I can see here the people are reusing similar components but want to confirm it if there are any legal restrictions around that.

I couldn't find anything specific in the agreement which only says that decompiling or modifying is not permitted which is not the case here.

IANAL so I can't speak to the decompiling but it's kinda uhm poor form... IMHO. But you shouldn't have to since JIRA provides the source for free if you have a valid license. 

One be word of caution - if you rely on non-public APIs - you'll have a hard time maintaining version compatibility.

[Atlassian Developer Terms]

(e) copy, frame or display any elements of the Atlassian Products through the Add-Ons or use the Atlassian Developer Assets with Add-Ons that substantially replicate any features or functionality of Atlassian Products, except as expressly authorized by Atlassian in writing; 

So if I decide to reuse lets say JQL auto completion will I need an authorization or not?

The issue is that from the usage terms or other docs I'm not able to tell which API is allowed and what are the usage conditions.

Where is that from? You may need to ask Developer Relations to for clarification: https://developer.atlassian.com/help#contact-us

I suspect that it's more that it's about reusing the Atlassian features in an non-atlasssian product. But again - I'm not a lawyer. Your best bet would be reach out to Developer Relations.
