Spring NoUniqueBeanDefinitionException for TransactionAttributeSource on ProGuard build - spring

Question

I have a maven based Java web application that contains Spring 5.2.0.RELEASE. When I try to obfuscate code with ProGuard 6.2.2, it builds with success. However, I'm getting following error when I try deploy the obfuscated war file on Apache Tomcat.
[ERROR] 2020-06-08 09:23:27.748 [localhost-startStop-1] ContextLoader [][][] Context initialization failed

Spring itself creates the bean that gets the error. So I can't trace the bugging code. Can you help me with this problem.

Thank you for spending time.

Answer 1

It was because of defining transaction manager twice (both xml and java)
Removing following line from context.xml solved the problem.
<tx:annotation-driven transaction-manager="transactionManager" />
The java side of transaction manager
/*
* https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/transaction/annotation/EnableTransactionManagement.html
* <tx:annotation-driven transaction-manager="transactionManager" />
*/
#EnableTransactionManagement
This normally doesn't cause a problem without obfuscation. Removing xml line fixed the problem.
