It works fine for me, I had a test with Maven 3.0.2 and the following POM :
<project>
...
<properties>
<prop.to.override>111</prop.to.override>
</properties>
<profiles>
<profile>
<id>profile-test</id>
<properties>
<prop.to.override>444</prop.to.override>
</properties>
</profile>
</profiles>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<id>default-jar</id>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<archive>
<manifestEntries>
<mode>development</mode>
<key>${prop.to.override}</key>
</manifestEntries>
</archive>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Then execute
1) mvn help:effective-pom -Doutput=pom-default.xml
<key>${prop.to.override}</key> => <key>111</key>
2) mvn help:effective-pom -Dprop.to.override=222 -Doutput=pom-override.xml
<key>${prop.to.override}</key> => <key>222</key>
3) mvn help:effective-pom -P profile-test -Dprop.to.override=333
-Doutput=pom-profile-override.xml
<key>${prop.to.override}</key> => <key>333</key>
4) mvn help:effective-pom -P profile-test -Doutput=pom-profile.xml
<key>${prop.to.override}</key> => <key>444</key>
