Spring Boot deployment — NoClassDefFoundError
I’m trying to deploy Spring Boot application. I build a jar file through maven plugins. But I get an error saying:
Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication at com.spring-boot.example.AppConfig.main(AppConfig.java:18) Caused by: java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) . 1 more I tried adding additional plugins to the pom.xml file, but none of it worked. Any help will be very appreciated. This is my pom.xml file:
4.0.0 com.spring-boot.example spring-boot-example 0.1 1.8 UTF-8 com.spring-boot.example.AppConfig 4.0.7.RELEASE 1.2.17 1.7 org.springframework.boot spring-boot-starter-parent 1.1.9.RELEASE org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-actuator org.springframework.boot spring-boot-starter-test test org.hibernate hibernate-validator org.springframework spring-test test org.springframework spring-jdbc 4.2.0.RELEASE org.springframework.boot spring-boot-starter-jdbc 1.2.1.RELEASE org.springframework.boot spring-boot-starter-tomcat provided org.springframework.boot spring-boot-maven-plugin Spring boot not running on Heroku
So I have a spring boot application build with Gradle. It’s working just fine when build and run locally, however, I can’t make it run on Heroku. Here are the logs:

I think by running locally, you mean running from target folder. copy the jar somewhere else and run, I suspect this wont work because the jar does not have required dependencies (hence class not found exception). If you see this is the issue, try creating fat jar using spring boot plugin.
@bestwishes by running locally I mean that I can build it as it is with IntelliJ, however when I push it to Heroku, it doesn’t build
