maven plugin share dependencies as provided - maven

Question

i want to know, if it is possible to provide dependencies from a custom maven-plugin to the project that include this plugin.
Example:
I have project a-maven-plugin:
<?xml version="1.0" encoding="UTF-8"?>
<project ...>
<groupId>some</groupId>
<artifactId>a-maven-plugin</artifactId>
<version>1.0.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>xxx</version>
</dependency>
</dependencies>
</project>
And a project that include this plugin:
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>some</groupId>
<artifactId>a-project</artifactId>
<version>1.0.0-SNAPSHOT</version>
<build>
<plugins>
<plugin>
<groupId>some</groupId>
<artifactId>a-maven-plugin</artifactId>
<version>1.0.0-SNAPSHOT</version>
<executions>
<execution>
<goals>
<goal>some.goal</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Now i want that the a-project has com.google.guava:guava:xxx with scope provided as dependencies.
Optimal i can choose in the in the plugin-pom which dependency i want to provide, that i only provide a part not all.
Is there a simple way?
