How can I add a project as a maven dependency (eclipse)

[quasi smelt]

On my previous eclipse version, if I added any project as a dependency in my second project, it worked well.
Now, I can't find how to do it.
I tried a local repo, but I now finish with NoSuchMethodError... (the dependency has the code, when compiled it has the code, but not in the repo? or idk, but it isn't existant in the second project jar file)

if anyone can help me thanks

have you tried using systempath?

<dependency>
    <artifactId>..</artifactId>
    <groupId>..</groupId>
    <scope>system</scope>
    <systemPath>${basedir}/lib/dependency.jar</systemPath>
</dependency>```
