  • java.lang.ClassNotFoundException: javassist.bytecode.ClassFile. So Javassist is not in the CLASSPATH. QED Commented Jan 27, 2018 at 9:15
  • Remove the hibernate dependencies from your list of dependencies. Those are already pulled in by the spring-boot-starter-data-jpa. Commented Jan 27, 2018 at 9:31

Reset to default

This is because you do not have javassist dependency in classpath or your IDE can not resolve classpath correctly.

  1. Try add this to pom and re-import

    <dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.22.0-GA</version>
</dependency>

  2. Try build the project using maven command
