How to set no-retry on activity option in java-sdk since max-retry has special meaning for 0?

Hey,

I want to set some activities no-retry at all by setting 0 to max-retry time. But the comment says 0 means default, so as far as I remember for retry in activities, the default is retrying forever. So how to totally stop retry for all kinds of failures ?

Hi @maki_XIE

There are a couple of ways you can achieve it:

• setMaximumAttempts to 1 What is a Retry Policy? | Temporal Documentation
• inside your activity, you can wrap your exception in a non-retryable ApplicationFailure throw ApplicationFailure.newNonRetryableFailure

Keep in mind that in both cases, the activity execution will throw an ApplicationFailure that will fail your workflow if you don’t catch it

Oh, sorry. I misunderstood. I thought maximum-attempts refer to retry-attempts count and I wonder why it starts from 1…
