Spring Application doesn't start due to missing EmbeddedServletContainerFactory bean

Question

I'm trying to deploy an application on heroku and came past several issues. The application is working in my IDE(Intellij) but when I try to run it with "heroku local -f Procfile.windows" I get this error:

Answer 1

For starters work with the framework instead of against/around the framework. Your dependencies are a mess and you aren't using the correct plugin.

First remove all of your plugins and replace with the spring-boot-maven plugin. (See also the reference guide for this).

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

Next cleanup your dependencies and use the proper (the Spring Boot managed) versions.

<dependencies>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-jpamodelgen</artifactId>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-batch</artifactId>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>

    <dependency>
        <groupId>org.flywaydb</groupId>
        <artifactId>flyway-core</artifactId>
    </dependency>

    <dependency>
        <groupId>org.assertj</groupId>
        <artifactId>assertj-core</artifactId>
        <version>3.4.1</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
    </dependency>

</dependencies>

Finally your application class is (somewhat) flawed you don't need that many annotations and you are extending a Spring Boot config class . What you are attempting to do in your overridden method is already provided by default by Spring Boot. So there is no need to do that. Also just put your App class in the cinematic top level package and everything else will be detected for you.

@SpringBootApplication
@EnableScheduling
public class App 

  public static void main(String[] args) {
      SpringApplication.run(App.class, args);
  }

}

Now rebuild your jar and launch it.

Note: The main issue was the fact that you weren't using the Spring Boot maven plugin but tried to do that yourself.

Answer 2

Goto C:\\Users\\username.m2\\repository\\org\\springframework\\boot

and delete spring-boot-autoconfiguration and build your maven again.

It will Work it will generate again.
