Which Jackson and Azure SDK versions are compatible for JMeter file uploads?

I'm attempting to upload a file from JMeter to an Azure fileshare, but I'm encountering a java.lang.LinkageError due to conflicting library versions.
Below is part of the error log:
JAVA2025-02-07 12:27:22,939 INFO c.a.c.i.j.JacksonVersion: Package versions: jackson-core=2.17.2, jackson-databind=2.17.2, jackson-dataformat-xml=2.17.2, jackson-datatype-jsr310=2.17.2, azure-core=1.53.0, Troubleshooting version conflicts: https://aka.ms/azsdk/java/dependency/troubleshoot 2025-02-07 12:27:22,939 ERROR c.a.c.i.j.ObjectMapperShim: Package versions: jackson-core=2.17.2, jackson-databind=2.17.2, jackson-dataformat-xml=2.17.2, jackson-datatype-jsr310=2.17.2, azure-core=1.53.0, Troubleshooting version conflicts: https://aka.ms/azsdk/java/dependency/troubleshoot 2025-02-07 12:27:22,939 WARN r.c.Exceptions: throwIfFatal detected a jvm fatal exception, which is thrown and logged below: java.lang.LinkageError: Package versions: jackson-core=2.17.2, jackson-databind=2.17.2, jackson-dataformat-xml=2.17.2, jackson-datatype-jsr310=2.17.2, azure-core=1.53.0, Troubleshooting version conflicts: https://aka.ms/azsdk/java/dependency/troubleshoot
I have reviewed the dependency versions and the troubleshooting link mentioned in the logs, but I'm unsure which Jackson and Azure SDK versions work together seamlessly for file uploads from JMeter. Any guidance on resolving these version conflicts would be greatly appreciated.

It looks like your question is related to uploading files to an Azure Files share using JMeter and dependency version conflicts, which isn’t in the scope of Azure Monitor and Observability. Could you please confirm or ask a question that falls within the Azure Monitor/Observability domain?

You're getting this error due to having 2 different versions of same library in classpath
The options are in:
- remove jackson libraries from lib folder of your JMeter installation
- remove jackson libraries from azure sdk
- consider other ways of uploading files, like you can mount azure fileshare as NFS or SMB/CIFS and access it like a local hard drive so the file can be copied using OS Process Sampler
- There is Azure Files REST API, you can upload your file via normal JMeter's HTTP Request sampler, see REST API Testing: How to Do it Right article for more information on the concept.
