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:

where are all answers are referring to building with Maven. Please put only answers related to Gradle here.
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:

I'm moving from a local application.yml configuration file to a config server managed configuration.
My application.yml file contains 2 (or more) profiles in the same file, in the format:
spring.application.name: config-client
app.myvar1: "Var 1 in default profile"
app.myvar2: "Var 2 in default profile"
---
spring.config.activate.on-profile: docker
app.myvar1: "Var 1 in docker profile"
When I test this configuration file in a NOT config-server environment, I the result reading from the specific profile, and if not found, reading from default. Sample
Correct result when I test without config-server
Profile: docker
MyVar1=Var 1 in docker profile
MyVar2=Var 2 in default profile
For testing I'm using a simple program:
package com.bthinking.configclient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
#RestController
public class ConfigClientApplication {
#Autowired
private Environment environment;
#Value("${app.myvar1:MyVar1 not found}")
String myVar1;
#Value("${app.myvar2:MyVar2 not found}")
String myVar2;
public static void main(String[] args) {
SpringApplication.run(ConfigClientApplication.class, args);
}
#RequestMapping("/")
public String index() {
StringBuffer b = new StringBuffer();
for (String profile : environment.getActiveProfiles()) {
b.append(String.format("Profile: %s</br>", profile));
}
b.append(String.format("MyVar1=%s</br>", myVar1));
b.append(String.format("MyVar2=%s</br>", myVar2));
return b.toString();
}
}
And I start the program with (I use gradle):
gradle :config-client:bootRun --args='--spring.profiles.active=docker'
But, when I migrate to config server, moving the file to a config-repo (I'm using file based repor), I get the invalid result (it's unable to read the variable in the default section). I have also tried with --spring.profiles.active=docker,default with no change
Profile: docker
MyVar1=Var 1 in docker profile
MyVar2=MyVar2 not found
For reference, my config-server has the following configuration:
server.port: 8888
spring.application.name: config-server
spring.cloud.config.server.native.searchLocations: file:${PWD}/config-repo
# spring.cloud.config.server.native.searchLocations: file:/Users/jmalbarran/Projects/BTH/BTH/SPB_SpringBoot/bugs/config/config-repo
logging.level:
root: debug
---
spring.config.activate.on-profile: docker
spring.cloud.config.server.native.searchLocations: file:/config-repo
The main class
package com.bthinking.configserver;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
#EnableConfigServer
#SpringBootApplication
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
And the build.gradle
plugins {
id 'org.springframework.boot' version '2.4.1'
id 'io.spring.dependency-management' version '1.0.10.RELEASE'
id 'java'
}
group = 'com.b-thinking'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
maven { url 'https://repo.spring.io/milestone' }
}
ext {
set('springCloudVersion', "2020.0.0")
}
dependencies {

testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
test {
useJUnitPlatform()
}
And I start it with:
gradle :config-server:bootRun --args='--spring.profiles.active=native'
NOTE: As I think this a bug, I have also created an issue in github. Check in Issue
After the #spencergibb (Thanks!) comment, I tried with the version 3.0.1, and it solves the problem.
This is now my build.gradle
plugins {
id 'org.springframework.boot' version '2.4.1'
id 'io.spring.dependency-management' version '1.0.10.RELEASE'
id 'java'
}
group = 'com.b-thinking'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
maven { url 'https://repo.spring.io/milestone' }
}
ext {
set('springCloudVersion', "2020.0.0")
}
dependencies {
implementation 'org.springframework.cloud:spring-cloud-config-server:3.0.1'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
test {
useJUnitPlatform()
}
It's amazing, because the version 3.0.1 is reported solving the opposite bug (the default configuration override the specific), but I imagine that the review solved both.

Issue#1777 Profile not correct with SpringBoot 2.4.1 + Ilford 2020.0.0 (working with 2.4.1 + Ilford 2020.0.0-RC1)

Goal: Adapting Prototype microservice example from Ch7 of Camel in Action by Claus Ibsen into a Gradle multi-module project.
I followed the Spring Guide to 'Creating a Multi Module Project' among other resources.
Project Structure:
+ main-mm-build
|--+ src
|--+ main
|--+ java // Spring Boot microservice (A) in this tree
|--+ build.gradle
|--+ settings.gradle
|--+ contact-manager // standalone-camel-spring microservice (B)
|--+ src
|--+ main
|--+ java // standalone-camel-spring microservice (B) here
|--+ build.gradle
Got as far as:
microservice A (Spring Boot Rest controller) can invoke microservice B (standalone Camel exposing rest() on jetty, without Spring DI).
But what I really want is to use Spring DI (without Spring Boot) in microservice B.
After making changes for camel-spring I get an error.
It's probably mucked up Gradle config, but I could use some help.

In order to use Spring Integration Amqp in a Spring Boot application, what are the dependencies I need to include?
Spring Boot version is 2.0.5.
Current dependencies I have are spring-boot-starter-integration and spring-integration-amqp
Error messages are classes like SimpleMessageListenerContainer and AmqpInboundChannelAdapter are not found on the classpath.
UPDATE:
My build.gradle entries --
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.5.RELEASE")
}
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-integration')
compile('org.springframework.boot:spring-boot-starter-amqp')
compile('org.springframework.integration:spring-integration-amqp')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
I had to add the following dependencies to resolve the classes in question (the last in the list did it, using latest spring initalizr, spring-boot 2.0.5)
dependencies {
implementation('org.springframework.boot:spring-boot-starter-amqp')
implementation('org.springframework.boot:spring-boot-starter-integration')
testImplementation('org.springframework.boot:spring-boot-starter-test')
compile 'org.springframework.integration:spring-integration-amqp'
}
To be fair, this answer was already given, just not for gradle.
I am using gradle 4.10.2 on a linux machine, spring-boot initialzr with the options RabbitMQ and Spring-Integration. Here are the changed files:
build.gradle
buildscript {
ext {
springBootVersion = '2.0.5.RELEASE'

Add this dependency:

<artifactId>spring-boot-starter-amqp</artifactId>
And are you sure you have this one?:
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-amqp</artifactId>
I have a SpringBootApp that I can run in eclipse by right-clinging and then selecting Run as -> Java Application. However, when I build a .war file and deploy it to my tomcat server. The console looks as though the application should have deployed but I'm unable to hit my rest services. I'm getting a 404 error. I really have no clue why it is not working so if anyone knows a solution could you explain why... Also, when I look in my war file i see all the classes files needed to deploy the application.

I am trying to write a custom Gradle Plugin that invokes the flyway migration using their API:
https://flywaydb.org/documentation/api/
This is a minimal example:
buildscript {
repositories.jcenter()
dependencies.classpath "org.flywaydb:flyway-core:4.1.2"
}
apply plugin: DatabaseHandlerPlugin
class DatabaseHandlerPlugin implements Plugin<Project> {
void apply(Project project) {
project.task("databaseHandler").doLast {
org.flywaydb.Flyway f = new Flyway(); // <= How can I use the above declared dependency here and in my projects?
}
}
}
But my gradle complains that it cannot load the Flyway class.
The Flyway class is in the org.flywaydb.core package. You missed the core bit. My full code that works:
import org.flywaydb.core.Flyway; // << can import here
buildscript {
repositories { mavenCentral() }
dependencies {
classpath "org.flywaydb:flyway-core:4.1.2"
}
}
apply plugin: DatabaseHandlerPlugin
class DatabaseHandlerPlugin implements Plugin<Project> {
void apply(Project project) {
project.task('databaseHandler') {
doLast {
Flyway f = new Flyway()
println "Flyway: $f"
}
}
}
}
Output:
> gradle databaseHandler
:databaseHandler
