My java project can't recognize a class from my other custom maven dependency from local repository

Question

I have issues with Maven 3 / Intellij .

As you see in this picture , I can't use my custom dependency classes in a new different project. it seems that intellij (same issue with eclipse) does not recognize the class IRunnableTask.java from the dependency scheduler (package : com.sifoklus.scheduler.task) although it's installed in my local maven repository and I can see it in External Libraries view in IntelliJ

Here is my local repository path from setting.xml

and the dependency is well installed in the same path :

and I added this dependency to my new project using :

Intellij is using the right settings file and the right local repo

I 've already tried to delete cache and restart . the problem is not fixed.

Do you know what is the problem and how it can be resolved ? Thank you

I tried to delete cache and restart . nothing changed

[[EDIT]]

Hello @romanv-jb

the error in 'problem' view says : cannot resolve symbol sifoklus (name of one folder in the package) . If I click more actions : one of the options is Add maven Dependency ,

when I click on this option , the intellij pop up finds the dependency but when I choose it , nothing changes. enter image description here

The code of Interface IRunnableTask is : enter image description here

Judging from the directory structure inside the com.sifoklus:scheduler jar file, it appears the repackage goal of the spring-boot-maven-plugin was run during its build. All the com.sifoklus.* classes should appear at the root rather than under BOOT-INF/classes.

If indeed scheduler has the plugin spring-boot-maven-plugin defined in its POM file, with an execution goal of repackage, try removing this plugin, and rebuild scheduler using mvn clean install.
