You declared a Maven dependency

<dependency>
  <groupId>com.myapp.Local</groupId>
  <artifactId>Local-2017</artifactId>
  <version>1.0</version>
</dependency>

If Maven does not find it in your local repository, it will try to download it from outside. If you do not have a settings.xml it will try MavenCentral.

In eclipse it works fine but when i use "mvn clean install -U" command on server it gives this error – Munib Deshmukh Feb 07 '18 at 11:10
The question is: Where does artifact lie? It looks like a project of yours that you need to build beforehand. – J Fabian Meier Feb 07 '18 at 11:50
it's build error, artifact lies with in the project – Munib Deshmukh Feb 07 '18 at 12:01

When you use Maven, you do not use artifacts in the project. You draw them from the local repository or a remote repository. Maven does not work that way. – J Fabian Meier Feb 07 '18 at 12:22

I suspect that part of the problem is that you have put the execution of "maven-install-plugin" into the "clean" phase. According to the Maven 3.5 Documentation, the "clean" phase is part of the "clean" life-cycle; i.e. gets run when you run "mvn clean".

I think it should be in the "default" lifecycle, probably the "validate" or "initialize" phase. Note that dependency resolution typically occurs in a later phase. It happens in the first phase that uses a plugin that requires dependency resolution as a prerequisite. Put the "install-file" goal into an earlier phase in the lifecycle.
