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

Benoit Larochelle

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. :-)

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.

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.

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>

                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>
</build>
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.

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:

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.

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

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

error start

it's happening because need commenting the code in main class, im my case

This error is because you are exporting the jar by eclipse. Soluction: after mvn clean install, just to use the jar generated in target folder
