Can’t find my tests with GitLab CI in kotlin - maven

Question

why gitlab-ci can't find my tests? locally in IntelliJ IDEA my tests works, but when i push into repo, gitlab-ci cant find my tests
Maybe the problem is that he can not find the directory of my tests? tests in:
project\src\test\kotlin\group\common\UObject\UObjectTest.kt
here is my pom.xml
<?xml version="1.0" encoding="UTF-8"?>

i modified <testSourceDirectory>src/test/kotlin/group/common</testSourceDirectory> but it still not works, i tried to use //Test. instead of **/Test. but it also doesn`t work, I think also problem could be in dependencies but i dont know them right, hope anyone could help me.
gitlab-ci just in case

Usually, GitLab CI, can't find the tests when you have placed them at a directory level that is not correct. Also, make sure that what you have in your pom.xml matches the actual directory hierarchy. In this case,
<testSourceDirectory>src/test/kotlin/group/common</testSourceDirectory>
Another example, from the Java world,
<testResources>
<testResource>
<filtering>false</filtering>
<directory>src/test/resources</directory>
</testResource>
<testResource>
<filtering>false</filtering>
<directory>src/test/java</directory>
<includes>
<include>**</include>
</includes>
<excludes>
<exclude>**/*.java</exclude>
</excludes>
</testResource>
