I created a jar file in intelliJ and it went ok, but when I do: java -jar fileserver-1.0-SNAPSHOT.jar

I get: Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication

EDIT: Cmd error

Mvn clean package: mvn clean package from intelliJ

    [INFO] Building fileserver 1.0-SNAPSHOT

I've been looking for other answers but no one worked for me. Hope someone can help

@Anna Actually `spring-boot-maven-plugin` adds the dependencies to the jar file. are you share `repackage` goal is executed? — badger, Mar 25 '22 at 11:14
@hatefalipoor don't understand, what do u mean with repackage? — Anna, Mar 25 '22 at 11:34
do you see this line in cmd `[INFO] --- spring-boot-maven-plugin:2.4.3:repackage (repackage) @ fileserver --- [INFO] Replacing main artifact with repackaged archive` — badger, Mar 25 '22 at 11:37
no, I don't see it, I updated the question with an screenshot of what cmd says — Anna, Mar 25 '22 at 11:39
@hatefalipoor no, I don't see it, I updated the question and copied what i get with mvn clean — Anna, Mar 25 '22 at 12:57
@hatefalipoor updated: added an image how I did it from intelliJ "mvn clean package from intelliJ" — Anna, Mar 25 '22 at 13:05

Either you code has some static references that is not getting resolved or the fat jar has some dependency library missing Why am I getting a NoClassDefFoundError in Java?
