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

We Are Going To Discuss About SpringBoot – making jar files – No auto configuration classes found in META-INF/spring.factories. So lets Start this Java Article.

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

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

    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.

Solution 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. 🙂

Solution 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

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.

Solution 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.
