You can use classifier to make the distinction between artifacts and reuse the classifier in the dependency.
defining a classifier
To do so you need to define the classifier in maven-jar-plugin:
<profiles>
<profile>
<id>profile1</id>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classifier>jdk6</classifier>
</configuration>
</execution>
</executions>
<plugin>
<plugins>
</build>
</profile>
<profile>
<id>profile2</id>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classifier>jdk7</classifier>
</configuration>
</execution>
</executions>
<plugin>
<plugins>
</build>
</profile>
</profiles>
using the classifier in dependency
Very simple:
<dependency>
<groupId>myGroup</groupId>
<artifactId>myArtifact</artifactId>
<classifier>jdk6</classifier>
<dependency>
