Possible incompatibility of Spring Boot Starter 3.4.0 with spring-cloud-azure 6.0.0-Beta.4

[JoanaPedrosoDiconium]

After upgrading spring-boot-starter-parent from version 3.3.5 to 3.4.0 I started getting this error when booting the application and running tests that require spring context:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'springCloudAzureDefaultCredential' defined in class path resource [com/azure/spring/cloud/autoconfigure/context/AzureTokenCredentialAutoConfiguration.class]: Unsatisfied dependency expressed through method 'tokenCredential' parameter 0: Error creating bean with name 'azureCredentialBuilderFactory' defined in class path resource [com/azure/spring/cloud/autoconfigure/context/AzureTokenCredentialAutoConfiguration.class]: Unsatisfied dependency expressed through method 'azureCredentialBuilderFactory' parameter 1: Error creating bean with name 'springCloudAzureCredentialTaskExecutor' defined in class path resource [com/azure/spring/cloud/autoconfigure/context/AzureTokenCredentialAutoConfiguration.class]: Failed to instantiate [org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor]: Factory method 'credentialTaskExecutor' threw exception with message: org/springframework/boot/task/TaskExecutorBuilder

This happens because TaskExecutionBuilder is no longer available for the AzureTokenCredentialAutoConfiguration which is a class loaded by the spring-cloud-azure-autoconfigure dependency with the version 6.0.0-beta.4 that we use in our project.

Any idea how to fix this?

Thank you!

TaskExecutorBuilder has been deprecated since Spring Boot 3.2.0. As per our deprecation policy, it was removed in Spring Boot 3.4.0. The required fix is for Spring Cloud Azure to switch to using ThreadPoolTaskExecutorBuilder, introduced in Spring Boot 3.2.0 instead.

You may want to raise an Azure Java SDK issue as recommended in the Azure docs.

Thank you for the reply and for the links! I did find an issue was already opened on their side to address this. For reference: Azure/azure-sdk-for-java#43085
