Maven: Could Not find Artifact when trying to include a project in another one using dependencies

Question

Problem description

I have a project called reservationVol which I want to include in an mvc spring project called reservationVolMvc. I compiled and tested reservationVol on eclipse. I also use the maven commands: mvn compile and mvn package. All tests ran successfully.

When I tried to compile reservationVolMvc using the mvn compile command I get the following error:

The following pom.xml files represent the dependencies for respectively reservationVol and reservationVolMvc. I included the project ReservationVol in reservationVolMvc by using the following:

<dependency>
    <groupId>hani.reservationVol</groupId>
    <artifactId>reservationVol</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

Answer 1

Do a mvn clean install.
This will clean whatever created from the previous build, then build your project and add the jars to your local maven repository (.m2\repository)
