SpringBoot - making jar files - No auto configuration classes found in META-INF/spring.factories

Question

Everything was working fine when starting my app using IntelliJ . But when I made a fat jar and executed it with

java -jar myapp.jar

I got this:

16:37:44.194 [main] ERROR org.springframework.boot.SpringApplication - Application startup failed

It looks like it doesn't found auto configuration classes in META-INF/spring.factories . How to add it, and what should be the content of this file?

Answer 1

I had the same problem and just solved it.

At first, I was generating the fat jar with the maven-assembly-plugin , which created a file called mavenproject1-0.0.1-SNAPSHOT-jar-with-dependencies.jar . This file gave the same problem as you mentioned when I tried running it.

I think that because it's a Spring Boot application, you need to use their plug-in. I changed my packaging to the spring-boot-maven-plugin and it generates two files: mavenproject1-0.0.1-SNAPSHOT.jar and mavenproject1-0.0.1-SNAPSHOT.jar.original . Just try java -jar target/mavenproject1-0.0.1-SNAPSHOT.jar , and it will hopefully work. :-)

Answer 2

This is the solution :

1. add only plugin in POM.xml

   <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <fork>true</fork> <mainClass>${start-class}</mainClass> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins>

2. One property in pom.xml

   <properties> <start-class>com.xxx.yyy.MainClass</start-class> </properties>

3. Run command

   mvn clean package spring-boot:repackage

4. Now run your jar (it includes all dependencies now) created inside target folder

    java -jar my-service-0.0.1-SNAPSHOT.jar

Answer 3

Alternatively, if you cannot use the spring boot plugin for whatever reason, you can include the following file in your application. It should be called src/main/resources/META-INF/spring.factories :

https://github.com/spring-projects/spring-boot/blob/1.5.x/spring-boot-autoconfigure/src/main/resources/META-INF/spring.factories

This will work for spring boot 1.x and is helpful if you want to use spring managed beans in a REPL.

Answer 4

This configuration works for me. I execute my JAR as a service but the line is:

javaw -jar MY_JAR.jar

POM :

<properties>
        <!-- Spring boot main class -->
        <start-class>com.PATH_TO_MAIN.Main</start-class>
</properties>
...
<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

With Spring Boot, it is no longer necessary to use the assembly-plugin. Do not forget to call the package goal.

Here is the documentation example .

Answer 5

I have added this configuration in my pom and the issue got resolved:

<build>
<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>1.5.2.RELEASE</version>
        <executions>
            <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>
</build>

Answer 6

Caused by: 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.

From above it seems that your packageing is not properly done. I know I'm late but it might help someone else.

Solution

Please check your @SpringBootApplication class shoud have base package all above the other classes. For example, let's your class @SpringBootApplication is inside a package com.sb.foo then all other spring stereotype classes should goes inside com.sb.foo.xxx where xxx can be anything. It can be further sub package com.sb.foo.xxx.yyy . This is a functionality of SpringBoot to enable Auto Configuration. This auto configuration works fine with IDE's like Intellij or Eclipse even if you have made the mistake.

The chances of facing such problem will be more if you're not using any building tool or recommeded IDEs like STS eclipse for development.

Answer 7

You could add the spring.factories file to your META-INF folder. The spring.factories file for Spring version 2.0.4 is located here: https://github.com/spring-projects/spring-boot/blob/v2.0.4.RELEASE/spring-boot-project/spring-boot-autoconfigure/src/main/resources/META-INF/spring.factories

Answer 8

For those of us new to IntelliJ, Spring, and Maven:

If you want to build a jar in IntelliJ, chances are you are using IntelliJ's build system: build, build artifacts, etc. However, that's not Maven. What you need is for Maven - not IntelliJ - to build it for you. To do this, you want to bring up the Maven panel in IntelliJ (under View => Tool Windows => Maven toward the bottom), and double click "package". Voila!

Answer 9

spring.factories is loaded by the AutoConfigurationImportSelector class in spring-boot-autoconfigure. This walks the context classloader for all resources of type META-INF/spring.factories.

To get spring boot to work after shading the jar, I simulated the same by merging the contents of all available spring.factories files into a single spring.factories file in my own jar's META-INF folder.

Here's my current spring.factories file:

Answer 10

I encountered the same problem:

IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories.

with Java 9, spring boot 2.0.0, springboot-javafx-support 2.1.6. I tried both maven and gradle 4 on the same project.

For me the fix was packaging the jar with java 8.

Answer 11

Met same problem and tried all above methods without success, then learned from Chinese coding website , and it resolved my problem:

Run following command in the Maven tool window Maven Projects->Execute Maven Goal

package -Dmaven.test.skip=true
