Spring Boot not starting as a standalone jar

Question

I am creating a independent jar using Spring Boot using Export command with Runnable Jar and trying to run the jar in command prompt but it is throwing the below error, the same application is running within eclipse. I cannot use maven and I am not using spring-boot-thymeleaf also in my application. Even after adding spring-boot-autoconfigurator-thymeleaf jar also I am getting this error.

Please suggest know why I am getting this error and I need to start the spring boot application jar as export->Runnable jar (as I cannot use maven to generate jar) and I should not get the above exception.

Spring tries to autoconfigure Thymeleaf, which causes the error. You do not need Thymeleaf, right? If that is correct, try figuring out why Thymeleaf is loaded. The Spring output mentions a debug flag which you should try. — C-Otto
Spring Boot requires a certain directory structure within the JAR. The Maven and Gradle plugin will create it automatically for you, however if you create the JAR yourself, you have to make sure that it has the structure which is needed. You can find out more about the structure in the documentation: docs.spring.io/spring-boot/docs/1.5.2.RELEASE/reference/… — dunni
If legacy XML jars are a problem, you might be able to use the maven build jar if you specify -Djava.endorsed.dirs on startup. — tunaranch

I am risking to get some downvotes but I think without maven you cannot include everything needed for a spring boot application to run because in the maven pom.xml you are including not only the dependencies, but also few plugins like tomcat plugin. So the next step for you is to start using build management tool as you are working with spring and spring boot that is almost mandatory in my oppinion. Maven is hard to master but easy to start and use so better take a look at this official simple tutorial: https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
