Issue Link 'blocks' in Jira

Hari Prasath P

I have created two issues(Issue 1, Issue 2) each contained in a separate sprint. Now, I link them using 'blocks' from Issue 1 to Issue 2, it means the Issue 1 should be completed before Issue 2. I have few questions over here,

1. Whether this link blocks Issue 2, not to get completed before Issue 1?
2. Does the Start and End date of Issue 2 changes when linked?

So, I cannot figure out how the issue link 'blocks' works. What this issue link 'blocks' does actually?

A link in Jira is just a link.  It shows a relationship between two issues, and nothing more.

"Issue A is blocked by Issue B" is useful information for us humans, but all Jira knows is "A <words> B".  You could rename it to "Issue A eats fish provides by penguins assigned to Issue B" and it would make no difference.

So the answers to 1 and 2 are both "no" because there's no way Jira can know you want to do that.  "blocks" is just the name for that type of link.

But, you can hang code off it if you want.  It's very common to see both of your questions implemented with post-functions, validators, or functions in apps like ScriptRunner, PowerScripts, Automation etc.
