java.lang.NoClassDefFoundError: when trying to run jar

Question

I have a spring boot project using gradle

apply plugin: \'java\'
apply plugin: \'idea\'
apply plugin: \'jetty\'
apply plugin: \'war\'
apply plugin: \'org.spr         


        

Answer 1

This is because your dependencies are not included into the end jar file.

Take a look on the examples here or here.

Or alternatively use ./gradlew clean build that should automatically pack the app correctly. Take a look on the official guide
