How to fix error: Couldn't find any of the CDI or Jakarta CDI Dependency types. Are you missing a dependency on your classpath?

Question

I upgraded my entity library to Hibernate 6.2.7 from version 5.6.15. Added some new DTOs and Mapstruct mappers. Suddenly I am getting following error:

error: Couldn't find any of the CDI or Jakarta CDI Dependency types. Are you missing a dependency on your classpath?

My build.gradle file is as follows:

    plugins {
    id 'java'

One of the Mapstruct mapper looks like this. It was autogenerated by JPA buddy plugin of IntelliJ Idea.

package com.iiotwizards.model.mappers;

import com.iiotwizards.model.UserManagement.UserAdminUsersEntity;
import com.iiotwizards.model.dtos.UserAdminUsersEntityDto;
import com.iiotwizards.model.UserManagement.UserTokenEntity;
import org.mapstruct.*;

@Mapper(unmappedTargetPolicy = ReportingPolicy.IGNORE, componentModel = MappingConstants.ComponentModel.CDI)
public interface UserAdminUsersEntityMapper
{
    UserAdminUsersEntity toEntity(UserAdminUsersEntityDto userAdminUsersEntityDto);

    @AfterMapping
    default void linkEmailSettings(@MappingTarget UserAdminUsersEntity userAdminUsersEntity)
    {
        userAdminUsersEntity.getEmailSettings().forEach(emailSetting -> emailSetting.setDefaultSender(userAdminUsersEntity));
    }

    @AfterMapping
    default void linkOpcAeConditions(@MappingTarget UserAdminUsersEntity userAdminUsersEntity)
    {
        userAdminUsersEntity.getOpcAeConditions().forEach(opcAeCondition -> opcAeCondition.setUser(userAdminUsersEntity));
    }

    @AfterMapping
    default void linkOpcAeEmailRecipients(@MappingTarget UserAdminUsersEntity userAdminUsersEntity)
    {
        userAdminUsersEntity.getOpcAeEmailRecipients().forEach(opcAeEmailRecipient -> opcAeEmailRecipient.setUser(userAdminUsersEntity));
    }

    @AfterMapping
    default void linkUserAdminPasswordResetTokens(@MappingTarget UserAdminUsersEntity userAdminUsersEntity)
    {
        userAdminUsersEntity.getUserAdminPasswordResetTokens().forEach(userAdminPasswordResetToken -> userAdminPasswordResetToken.setUserId(userAdminUsersEntity.getId()));
    }

    @AfterMapping

    {
        userAdminUsersEntity.getUserAdminVerificationTokens().forEach(userAdminVerificationToken -> userAdminVerificationToken.setUserId(userAdminUsersEntity.getId()));
    }

    @AfterMapping
    default void linkUserEmails(@MappingTarget UserAdminUsersEntity userAdminUsersEntity)
    {
        userAdminUsersEntity.getUserEmails().forEach(userEmail -> userEmail.setUser(userAdminUsersEntity));
    }

    @AfterMapping
    default void linkUserImages(@MappingTarget UserAdminUsersEntity userAdminUsersEntity)
    {
        userAdminUsersEntity.getUserImages().forEach(userImage -> userImage.setUser(userAdminUsersEntity));
    }

    @AfterMapping
    default void linkWebUiUserToken(@MappingTarget UserAdminUsersEntity userAdminUsersEntity)
    {
        UserTokenEntity webUiUserToken = userAdminUsersEntity.getWebUiUserToken();
        if (webUiUserToken != null)
        {
            webUiUserToken.setUserAdminUsersEntity(userAdminUsersEntity);
        }
    }

    UserAdminUsersEntityDto toDto(UserAdminUsersEntity userAdminUsersEntity);

    @BeanMapping(nullValuePropertyMappingStrategy = NullValuePropertyMappingStrategy.IGNORE)
    UserAdminUsersEntity partialUpdate(UserAdminUsersEntityDto userAdminUsersEntityDto, @MappingTarget UserAdminUsersEntity userAdminUsersEntity);
}

Answer 1

Use componentModel = "spring" instead of componentModel = "cdi" in the @Mapper annotation of MapStruct. By specifying componentModel = "spring", MapStruct produces the mapper as a Spring bean, simplifying injection into other Spring components. Alternatively, you can include the necessary dependencies for CDI ("cdi") to achieve the desired functionality.
