java.lang.NoClassDefFoundError errror due to not being able to find
com.equiz.project.EquizApplication.main
The pom file specifies com.equiz.project.EquizApplication.
I think this is happening because Railway is adding "main" to the end of the build path.

I use Maven. My POM file build section:
org.apache.maven.plugins
maven-jar-plugin
true
com.equiz.project.EquizApplication
Package path:
com.equiz.project
Main application class name:
EquizApplication
Below is the build error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication
at com.equiz.project.EquizApplication.main(EquizApplication.java:11)

I hate Java.
I hate Maven even more. Using Maven over Gradle in 2025 is literally insanity.
You should ask your question in a SpringBoot targeted server. People here are not fluent in SpringBoot, and your issue has nothing to do with Railway.

It works now. Below is the build section I used.
This is a Java project using SpringBoot framework with Maven for dependency management.
org.springframework.boot
spring-boot-maven-plugin
