How to release and reference Grails plugins using local Maven repository - maven

Question

Summary
I create two plugins A and B with Grails 2.3.4 where B is a plugin used by A plugin. I get error when I use A plugin in my application.
Details
When I run the following command, for plugin B, it successfully release the plugin to local maven repository. I can see it in the ~/.m2/... folder.
~plugin-b: grails maven-install
Then I add a reference to plugin B with plugin A, so I add the reference to BuildConfig in plugin A:
plugins {
compile "com.test.plugins:b:1.0.0-SNAPSHOT"
}
Now, I think, I should be able to run the next command and the plugin should be released to the local maven repository but I get the error instead:
~plugin-a: grails maven-install
| Plugin packaged grails-a-1.0.0-SNAPSHOT.zip
| Generating POM file.....
| Error Could not find artifact com.test.plugins:b:jar:1.0.0-SNAPSHOT (scope: compile) (Use --stacktrace to see the full trace)
| POM generated: //dependencies/dependencies_A_plugin/target/pom.xml...
Maven install complete.
Here is the generated POM file:
// pom header
<artifactId>a</artifactId>
<packaging>zip</packaging>
<version>1.0.0-SNAPSHOT</version>
<name>A</name>
<description>Brief summary/description of the plugin.
</description>
<url>http://grails.org/plugin/a</url>
<developers>
<developer>
<name>Your name</name>
</developer>
</developers>
<dependencies>
<dependency>
<groupId>com.test.plugins</groupId>
<artifactId>b</artifactId>
<version>1.0.0-SNAPSHOT</version>
<scope>compile</scope>
</dependency>
... just ending tags
Actually, also plugin A has been released to the local Maven repository, but it is probably corrupted, because when I create a Grails application and add a reference to A plugin into BuildConfig, then I am not even able to start up that application.
~ grails
| Error Resolve error obtaining dependencies: Could not find artifact com.test.plugins:b:jar:1.0.0-SNAPSHOT (Use --stacktrace to see the full trace)
| Error Could not find artifact com.test.plugins:b:jar:1.0.0-SNAPSHOT
So, the application has found A plugin, but not the B plugin, which is referenced by A plugin. To me, it seems there is an issue with generated POM file in the local Maven repository for the A plugin. There is probably missing:
<type>zip</type>
But I have not found a way how to add the type to that dependency.
Anyone able to help?
