Could not resolve dependencies for project. Could not find artifact.

Question

I have a problem with building a project Farma-rest which depends on my other project Farma. I put dependency in my pom.xml but it couldn't resolve dependencies for the project. It shows me this error message:

Failed to execute goal on project Farma-rest: Could not resolve dependencies for project sk.upjs.ics:Farma-rest:jar:1.0-SNAPSHOT: Could not find artifact sk.upjs.ics:Farma:jar:1.0-SNAPSHOT -> [Help 1]

Here is the pom of the first project:

    </dependencies>
</project>

I tried to clean and build the project but it didn't helped.

Answer 1

The jar for the Farma project is not available in your local maven repo.

1. Check if the ~/.m2/repository/sk.upjs.ics/Farma/1.0-SNAPSHOT directory exists. It should not at this point.
2. Run the build for the Farma project. Maven should create the artifact and put it in your local maven repository.
3. Check the same directory as before. It should now exist and it should have a jar and pom in it.
4. Now try building Farma-rest again and it should work.
