OauthSampler from JMeter 3.0 to JMeter 3.3 - plugins

Question

I have a test plan that works great in JMeter 3.0 (it was conceived with this version).
I tried to upgrade JMeter to 3.3 and now I have few new errors.

How can I overcome this error? I know that OAuth Sampler is deprecated. Is there a way to fix this? Also I have some error when I try to read from a file (might not be related).

Answer 1

Looking into commit 2651c6ffc534e0137849377fce4b1b0e1aafca47 the file src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPSampler2.java has been removed as a part of issue 60727 during JMeter 3.2 release
So maximum JMeter version you can use with OAuth Sampler is JMeter 3.1.
You can reach out to JMeter Plugins developers and/or maintainers via JMeter Plugins Forum and clarify the status and the plans or use one of alternative approaches described in How to Run Performance Tests on OAuth Secured Apps with JMeter, they should be JMeter-version-agnostic.
You can download JMeter 3.1 from Apache JMeter Archives page
