Gradle build with fatJar plugin and SpringBoot application gives 'Application startup failed' - gradle

Question

Everything was working fine when starting my app using Intellij. But when I made fatJar (with gradle plugin: eu.appsatori.fatjar) and execute:
java -jar myapp.jar
I'm getting something like this:
11:41:01.224 [main] ERROR org.springframework.boot.SpringApplication - Application startup failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [my.testing.MyAppMain]; nested exception is java.lang.IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.
at org.springframework.context.annotation.ConfigurationClassParser.processDeferredImportSelectors(ConfigurationClassParser.java:482)
at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:184)
...
It looks like it didn't found auto configuration classes in META-INF/spring.factories.
How to add this file? And what should be the content of it?
I've got following build script:
apply plugin: "java";
apply plugin: "idea";
apply plugin: 'application'
apply plugin: 'eu.appsatori.fatjar'
apply plugin: 'org.springframework.boot'
repositories {
mavenCentral()
}
buildscript {
ext {
springBootVersion = '1.4.3.RELEASE'
}
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"
classpath "eu.appsatori:gradle-fatjar-plugin:0.3"
}
}
sourceSets {
main {
java {
srcDir 'src/main/java'
}
resources {
srcDir 'src/main/resources'
}
}
test {
java {
srcDir 'src/test/java'
}
}
}
fatJar {
manifest {
attributes("Main-Class": 'my.testing.MyAppMain')
}
exclude 'META-INF/*.DSA'
exclude 'META-INF/*.SF'
exclude 'META-INF/*.RSA'
}
dependencies {
compile 'org.springframework.boot:spring-boot-starter-jdbc'
runtime 'mysql:mysql-connector-java'
testCompile 'org.springframework.boot:spring-boot-starter-test'
}
And my example code is:
package my.testing;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;
#SpringBootApplication
public class MyAppMain {
private ConfigurableApplicationContext springContext;
#Autowired
private SimpleDao dao;
public static void main(String[] args) throws Exception {
MyAppMain test = new MyAppMain();
try {
test.init();
test.doWhatYouGotToDo();
} finally {
test.stop();
}
}
private void doWhatYouGotToDo() {
System.out.println("Auto-wired dao: " + dao.hashCode());
System.out.println("Auto-wired jdbcTemplate: " + dao.jdbcTemplate.hashCode());
}
private void init() throws Exception {
springContext = SpringApplication.run(MyAppMain.class);
springContext.getAutowireCapableBeanFactory().autowireBean(this);
}
private void stop() throws Exception {
springContext.close();
}
}
#Component
class SimpleDao {
#Autowired
JdbcTemplate jdbcTemplate;
}
application.properties file:
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/some_db?useSSL=false&serverTimezone=UTC
spring.datasource.username = some_user
spring.datasource.password = some_pass
NOTE: This question is based on SpringBoot - making jar files - No auto configuration classes found in META-INF/spring.factories
where are all answers are referring to building with Maven. Please put only answers related to Gradle here.

Answer 1

Although I mostly use Maven for Spring and Gradle for Android, but here is the gradle way for a Spring project:
gradle clean build
gradle bootRepackage
Result:
Here is my build.gradle file:
