I had project on Java (Spring Boot) that consists from few modules:

```
parent-pom
    mod1-pom
    mod2-pom (depends on mod1)
    mod3-pom (depends on mod1 and mod2)

```

After I rewrite modules to Kotlin I can’t do `maven install` for parent-pom and I can compile only pom1. For modules that depends on another module I see Errors like: `Unresolved reference: mod1`

I recreate project with clean poms. Change build scripts to default.  
`mvn package` and `mvn install` can make packages only after `mvn compile` without this command same errors.

Looks like without `mvn compile` no target/classes folder in which compiler search for classes.
