I am so confused as to why I can run it in IDE but not as a jar. Also I found out that my jar doesn't contain any libraries at all.
EDIT:
This is my Application.class
package some.application;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class Application
{
public static void main(String[] args)
{
SpringApplication.run(Application.class, args);
}
}
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
Define a task called fatJar in build.gradle:
jar {
baseName = 'base-name'
version = '0.1.0'
manifest {
attributes(
'Main-Class': 'com.github:'
)
}
}
task fatJar(type: Jar) {
manifest.from jar.manifest
// classifier = 'all'
from {
configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
artifacts {
archives fatJar
}
Run gradle fatJar or ./gradlew fatJar to generate a jar file with all dependencies, which can run independently but may be pretty large in size (that's why it's called a fat jar).

I have setup a gradle multi project in java. The build was successful but when I tried to run the JAR, a java.lang.NoClassDefFoundError was thrown.

The error message says that it cant find a class in my common package.
I don't know why because I used compile project (':common') in my authserver gradle configuration
Here is the command: java -jar authserver/build/libs/authserver.jar
Thank you for your help and have a nice day !
For me worked next thing: in kotlin I haved spring boot plugin applied to all subprojects {} in root build.gradle
Instead of this I've removed
apply(plugin = "org.springframework.boot") from root build.gradle and applied this line for each subproject instead of common module
I think the issue is that the JAR you are creating does not include the class files generated from compiling the common module. Try ammending the jar task of authserver module so that you include the output of compiling the common module:
jar {
from project.sourceSets.main.allSource
from project(":common").sourceSets.main.java.output
manifest {
attributes 'Main-Class': 'fr.evywell.robserver.auth.Main'
}
}
I used the shadow plugin to build a "fat jar". I don't know if it's a good practice...
Thank you for your help !

Now I am using Java 8 and Spring I am doing it with intellij from File>Project Structure>Artifacts, there I choose ProjectRoot main module and then also add my resources directory content and I build the jar.

My RestaurantAplication.class is was in my restaurant folder, but I read somewhere that it should be above my package with my classes, so I moved it to the projectId folder, but it didn't work.
My main:
#SpringBootApplication
#EnableScheduling
#EnableConfigurationProperties
public class RestaurantApplication {
public static void main(String[] args) {
SpringApplication.run(RestaurantApplication.class, args);
}
}
Edit: in the jars's spring.factories in the META-INF folder there is only one line:
org.springframework.beans.BeanInfoFactory=org.springframework.beans.ExtendedBeanInfoFactory
I tried adding them to the file also adding some of the ones listed in the error and also my config files:
org.springframework.beans.BeanInfoFactory=org.springframework.beans.ExtendedBeanInfoFactory
org.springframework.boot.autoconfigure.AutoConfigurationImportSelector
org.springframework.context.annotation.ConfigurationClassParser
com.projectId.restaurant.config.AppConfig
com.projectId.restaurant.config.PasswordEncoderConfig
com.projectId.restaurant.config.ScheduleConfig
com.projectId.restaurant.config.Scheduler
com.projectId.restaurant.config.SecurityConfig
But even then the lines in the error still exist for the exact configurations I have added:

How to solve this?
You are including two different versions of the jackson lib. For Spring 4+ use the com.fasterxml.jackson.core like you have. Remove the two org.codehaus.jackson dependencies.
