I have the following folder structure in a Java project:
main-module (Java module)
sub-module-to-import (Java module)
ImportedClass.java
sub-module (Java module)
fx-sub-module (JavaFX module)
- pom.xml and classes.
Whenever I import sub-module-to-import into fx-sub-module from maven, I can access ImportedClass.java after importing it in fx-sub-module's classes (instantiate the class, access its methods etc. in the IDE), but whenever I try to compile the module using mvn clean compile
, I get a compilation error of type "cannot find symbol", where the symbol is a method of ImportedClass. Whenever I reload the maven project after adding the module as a dependency, everything is okay, with no XML errors or warnings, I can even ctrl + left click on sub-module-to-import's name and get sent to its pom.xml without issues. The project is a modular one, but I have removed the module-info file in order to not have to use modularity. I am using IntelliJ IDEA.
Here is the pom.xml file:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

After reading a lot about it on the internet and not managing to find a solution, I tried simple things like adding sub-module-to-import to the parent pom.xml of fx-sub-module (which is the pom.xml file of sub-module), but that didn't change anything. I also tried changing plugin/dependency versions, but this also did not help. I would really appreciate any help and will be quick to answer for further clarification on the question. Thanks in advance.
Ensure:
mvn install
has been run on the sub-module-to-import
maven module.
