maven release:prepare namespace prefix "xsi" collides with an additional namespace declared by the element

I'm getting this error while I run maven release:prepare on this parent pom.xml. It's a multi-modules maven project. I tried a lot of things but i still could not fix this, it seems like there is something strange somewhere. I run the same release:prepare on other project and there was no problem.

The problem was that one of the multiple module had this https instead of http but logs didn't mention the cause module

    <project
        xsi:schemaLocation="https://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"
        xmlns="https://maven.apache.org/POM/4.0.0"
        xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance">
