I launch my app in eclipse and works fine and I got the initialization of de entityManagerFactory by default as I wish:

2022-11-28 13:32:58.558  INFO 12176 --- [  restartedMain] j.LocalContainerEntityManagerFactoryBean : Initialized JPA EntityManagerFactory for persistence unit 'default'

but when I deploy my app by a runnable jar file it is not launching, I'm sharing this question after much research, here is my pom (I'm extracting the libraries into generated jar):

I thinks it is possible a incompatibility from one spring-boot version to another dependency, but I'm not certain. Also attach the console trace.

ZpectrumApplication: Cannot create inner bean '(inner bean)#71a9b4c7' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#71a9b4c7': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' available

You have to build and package the jar with dependencies, add the below to your plugins in the pom.xml, change the main mainClass to yours.

I solve it by deploying the project by command prompt in the next three steps:

• downloading Apache-Maven https://maven.apache.org/download.cgi
• following this tutorial: https://www.youtube.com/watch?v=-ARoNTL90hY
• modifying the pom.xml with manual configuration -> https://www.baeldung.com/executable-jar-with-maven
