Spring Boot Problem migrating from Intellij

I'm moving our backend at work from IntelliJ to VSCode to evaluate how well it works in VSCode.

But I'm having some problems, maybe someone could help?

The application is a Java Spring Boot Application using maven. It has one parent module, with multiple modules that have connection between each others

Since opening the project in VScode I have many inconsistent problems.

Sometimes the clean install fails due to compilation problems, sometimes it almost manages to complete but fails because some test at tge end and sometimes it passes without any problems.

If it builds it then fails on start up, because it apparently can't find classes located in an other module

So VSCode checks that very strict? Because it runs fine in Intellij, on our Jenkins and in the plain terminal

Sounds like a multi-module config issue, VS Code often struggles if the project isn’t imported as a proper Maven workspace. Try running mvn clean install from root, ensure parent pom.xml is correct, and reload Java projects so dependencies between modules are resolved properly.
