"Dependency problems found" when `mvn clean install` a che plugin project

Question

I downloaded the che plugin project example che-ide-server-extension. It works when mvn clean install. But when I add a dependency in

che-ide-server-extension/plugins/plugin-serverservice/plugin-serverservice-ide/pom.xml

, it fails to install.

The dependency I added is

<dependency>
    <groupId>org.eclipse.che.core</groupId>
    <artifactId>che-core-ide-ui</artifactId>
</dependency>

And the error message of mvn clean install -e -X is:

...

I don't think I added a wrong dependency. Because when I

import org.eclipse.che.ide.ui.dialogs.DialogFactory;

in my java code, che says

The import org.eclipse.che.ide.ui.dialogs cannot be resolved.

But after I added the dependency, che can recognize it.

I don't know why this happens... The error message says Dependency problems found, but it didn't point out the real problem...

I've just checked and I didn't face any issues you mentioned above. This my changes for the project:

btw I `git checkout 6.16.0` after `git clone https://github.com/che-samples/che-ide-server-extension`. (I have to use 6.16.0 version. Sorry for forgetting to say that). And then I edit the pom.xml. And finally `mvn clean install`. — Oopssss, Jul 10 '19 at 11:44
