How to call Multiple REST Client from Quarkus Controller?

Question

Does Quarkus controller allow to use multiple rest clients? I pretty much tried everything in my power to figure out what I might be doing wrong but No success.

I am using below variables to point to open jdk 11 JAVA_HOME and JDK_HOME ( openjdk-11.0.2_windows-x64_bin ) graal vm GRAALVM_HOME ( graalvm-ce-java11-22.3.0 ) maven ( Apache Maven 3.8.6 )

Build works fine when running it using below commands mvn clean mvn install mvnw quarkus:dev

Issue happens in controller.
// IT BLOWS UP ON BlockHeaderController in method public BlockHeaderDTO addBlockHeader(BlockHeaderDTO dto) throws Exception

If I comment out this call to blockTypeCategoryService, then all services defined in controller works. I am not sure why controller allows to use Client: masterCustomerSetService but it is not liking client: blockTypeCategoryService

 /*  IF commented out this code then service works fine. 
    Optional<BlockTypeCategoryDTO> blockTypeRec =
            blockTypeCategoryService.getBlockTypeByCategoryAndType(
                    inputEntity.getBlockTypeCode(), "Costshare");
    if (blockTypeRec.isPresent()) {
        inputEntity.setBlockTypeCategoryId(blockTypeRec.get().getBlockTypeCategoryId());
    }
    */

I pretty much tried all tricks Trick 1 : changing scope of clients in properties file (ApplicationScope, Singleton, SessionScope ) all 3 doesn't work! Trick 2 : Using jandex-maven-plugin as described here : https://quarkus.io/guides/cdi-reference ( in addition to modifying application.properties with quarkus.arc.unremovable-types=demo.rest.clients.* )

**BlockHeaderController.java**   This is main Controller which use two clients 
BlockHeaderDTO.java
**MasterCustomerSetService.java**  This client works just fine! 
CustomerSet.java
**BlockTypeCategoryService.java**  This client gives problem for some reason 
BlockTypeCategoryDTO.java
BlockHeaderMapperImpl.java
BlockHeaderMapper.java
BlockHeaderRepository.java
BlockHeader.java
application.properties
pom.xml

        return blockHeaderMapper.toBlockDTO(blockHeaderRepository.save(inputEntity));
        */

        // After commenting about above code using /* .. */  code works.
        // code doesn't faile when calling client1 : masterCustomerSetService.getMasterCustomerSetByName
        // Not sure why calling client2 : blockTypeCategoryService.getBlockTypeByCategoryAndType is problem
        return blockHeaderMapper.toBlockDTO(inputEntity);

    }

}

Answer 1

I solved it! Issue was with conflicting client Jars.
