@amishra-dev could you please follow up with @kirankbs?

Hi @kirankbs (Kiran),
We discovered an issue in older versions listed below of the SDKs for Storage which we have removed from Maven. To upgrade to the latest version please change the dependency version in your pom.xml to a newer one listed below. We strongly recommend moving to the latest SDK if you are using any of these affected versions.

If you need to use an older Azure Storage REST API version, please read the sample here about using an older Service Version with a newer SDK. We apologize for the inconvenience this may have caused.

SDK	Versions Removed	Recommended Version
Azure Storage Blob	12.0 to 12.6.1	12.14.1
Azure Storage File Datalake	12.0 to 12.1.2	12.7.1
Azure Storage File Share	12.0 to 12.4.1	12.11.1

If you need further help
please create a ticket at aka.ms/azsupt.

Issue Type: Technical
Service Type: Blob Storage
Summary: #JavaSDKv12
Problem type: Development
Problem subtype: Client library or SDK

@amishra-dev In your guidelines it states:

Dependable

• 100% backward compatible

This is not true in the current case for 2 different reasons:

• library is completely removed, so we can't go back or develop locally with the current version as is doesn't exist.
• updating to 12.14.1, which is a minor bump, introduces a new constructor, which means a breaking change.

As you also state in the guidelines:

Consistent

• All differences from the guidelines must have good reasons.

I assume there is a serious issue that you are trying to manage and you have a good reason for that.
I'm interested in what's being done for these situations not to happen again?
