Issue
I have a problem. I created 2 maven projects and copied both the folders to my Ubuntu server. When I want to mvn package program A, which has included the dependency of project B (Simulator):
<dependency>
<groupId>com.simulator</groupId>
<artifactId>simulator</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
It says:
[ERROR] Failed to execute goal on project hatop: Could not resolve dependencies for project com.hatop:hatop:jar:1.0-SNAPSHOT: Could not find artifact com.simula tor:simulator:jar:1.0-SNAPSHOT -> [Help 1]

I have already packaged the simulator project so there is a .jar file in the target folder of that package. Running it in Visual Code on my windows desktop works fine and the project get's packaged. What is causing this and how can I fix this?
Solution
You need to run mvn install on the dependency first.
