Spring Roo multimodule.roo doesn't compile: Failed to resolve local artifact

Question

I have set up a project using multimodule.roo which is provided with spring roo 1.2.3.

However, when i run 'mvn tomcat:run', it gives the following error:

Missing:
----------
1) com.example.petclinic:core:jar:0.1.0.BUILD-SNAPSHOT

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=com.example.petclinic -DartifactId=core -Dversion=0.1.0.BUILD-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there: 
      mvn deploy:deploy-file -DgroupId=com.example.petclinic -DartifactId=core -Dversion=0.1.0.BUILD-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency: 
    1) com.example.petclinic.ui.mvc:mvc:war:0.1.0.BUILD-SNAPSHOT
    2) com.example.petclinic:core:jar:0.1.0.BUILD-SNAPSHOT

----------
1 required artifact is missing.

for artifact: 
  com.example.petclinic.ui.mvc:mvc:war:0.1.0.BUILD-SNAPSHOT

from the specified remote repositories:
  spring-maven-milestone (http://maven.springframework.org/milestone),
  central (http://repo1.maven.org/maven2),
  spring-roo-repository (http://spring-roo-repository.springsource.org/release),

Here is my part of the root pom.xml

<modules>
        <module>core</module>
    <module>ui</module>
    </modules>

Now, inside the ui module, there is another module named mvc whose pom.xml contains:

<dependency>
            <groupId>com.example.petclinic</groupId>
            <artifactId>core</artifactId>
            <version>0.1.0.BUILD-SNAPSHOT</version>
        </dependency>

The packaging of core module is jar.

Now, as far as I understand, Maven is trying to locate a local artifact 'core' in remote places. That's why its getting this error.

How can I prevent maven from searching for this local artifact in remote places? Or am I getting some other problem?

RE: I've found a great blog post, my problems seem to have vanished

Please have a look at this link:

Answer 1

I had the same error when trying to run the mvc module via

mvn jetty:run

The error i got was

Could not find artifact com.example.petclinic:core:jar:0.1.0.BUILD-SNAPSHOT

The problem was that I didn't installed the artifact core in my Maven repository. So I went back to the project root and a simple

mvn install

installed the artifact.

After that I was able to start the jetty server.
