I'm doing simple api with Spring Boot and embeeded database and it's hits me an

NoClassDefFoundError. : Error creating bean with name 'entityManagerFactory'

Maybe you know which dependency I should include to my pom.xml. Maven project. here is what i have:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.derby</groupId>
        <artifactId>derby</artifactId>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

NoClassDefFoundError has javadocs. docs.oracle.com/javase/7/docs/api/java/lang/… a class or a dependency of that class is not in the CLASSPATH. Nothing (explicitly) to do with the JPA or anything, just basic Java – user8558216

hibernate-core and hibernate-entitymanager are being transitively included via spring-boot-starter-data-jpa

Edited: Could you first try removing you local .m2/repository? Sometime it gets corrupted.

rm -rf ~/.m2/repository

Could you include which Spring Boot version are you using pom.xml content.

Could you also include you data source and JPA properties?

1) Make sure none of your dependencies (except spring-boot-starter-data-jpa) have inclusive dependency to hibernate-core. Otherwise libraries may get clashed.

2) You may also need to add this artifact:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
</dependency>

Version should be inferred.
