I have upgraded my java azure function dependencies from Spring boot 3.3.0 -> spring boot 3.4.0 and using the below dependencies.
com.microsoft.azure.functions:azure-functions-java-library:3.1.0
org.springframework.cloud:spring-cloud-function-dependencies:4.2.0
com.google.code.gson:gson:2.8.9
Now, I start seeing issues. I tried upgrading the gson version 2.11.0/2.10.1 and even removed it but I still getting the below error.
WARNING: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gsonBuilder' defined in class path resource [org/springframework/boot/autoconfigure/gson/GsonAutoConfiguration.class]: Failed to instantiate [com.google.gson.GsonBuilder]: Factory method 'gsonBuilder' threw exception with message: 'com.google.gson.GsonBuilder com.google.gson.GsonBuilder.setStrictness(com.google.gson.Strictness)'
adding more error details below:

What is the right version of GSON to use along with spring boot 3.4.0 , spring framework 6.2.0 and azure functions java library 3.1.0?
Thanks in advance for the help :).

The issue could be due to the conflict between dependencies versions you have used.
Thanks for the insights @E.Makarovas.
Spring Boot has the correct gson jar configured as a dependency which will be included in your build automatically. When you specify a dependency to gson explicitly, it overrides the default dependency version brought by Spring Boot.
To resolve this error:
gson from your pom.xml (or) build.gradle.com.google.code.gson:gson to 2.11.0.com.microsoft.azure.functions:azure-functions-java-library:3.0.0
org.springframework.cloud:spring-cloud-function-dependencies:4.0.0
com.google.code.gson:gson:2.11.0
Gson class or exclude "AutoConfiguration" for Gson class by adding below line in the Main class of Spring Boot Application:@EnableAutoConfiguration(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
Code Snippet:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableAutoConfiguration(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
public class DemoApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(DemoApplication.class, args);
}
}
I have created a Spring Boot Azure function with latest versions of the libraries.
