How to resolve issue with Maven dependencies "Failed to execute goal on project"

Question

I have got the following structure in Eclipse of my maven projects:

MainMavenProject
---MyProject
---MProject-client
---MProject-xyz
---MProject-web
...

In Eclipse, I use JBoss 7.1 to run MProject-web:

Now, I want to run Jetty with another project. From directory /MainMavenProject/MyProject I run a command

mvn -Djetty:port=8081 jetty:run

It has been finished with an error:

[ERROR] Failed to execute goal on project MyProject: Could not resolve dependencies for project ***.*****.MyProject:MyProject:war:0.0.1-SNAPSHOT: The following artifacts could not be resolved: ***.*****.********:MyProject-client:jar:1.0.

In MyProject, I use depedencies to the other ones:

<dependency>
    <groupId>com.*****.********</groupId>
    <artifactId>MyProject-client/artifactId>
    <version>1.0.1-SNAPSHOT</version>
</dependency>

<dependency>
    <groupId>com.*****.********</groupId>
    <artifactId>MProject-xyz</artifactId>
    <version>1.0.1-SNAPSHOT</version>
</dependency>

How can I check, what exactly happend and after that, how to fix it?

Thank you in advance

Solution

Try running mvn install on the Main project first.

Your project is missing the other modules, which likely have never been installed to local repository.

Not that you would have to run install every time before running jetty:run.

An alternative would be to use the eclipse, right click MyProject -> Run as -> Maven build..., enter -Djetty:port=8081 jetty:run in the goals field and check "Resolve workspace artifacts".

Hi, I did mvn clean and I still have the same problem. I prefer to use jetty in command line. Can I run Resolve workspace artifiacts not from Eclipse ?

@IWillTryToCodeIt No (at least not without some very dirty tricks). Do mvn clean install from Main project. Does it work?
