regarding the warning
[WARNING] 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: javax.servlet:servlet-api:jar -> version 2.4 vs 2.5 @ line 77, column 17
You probably have a transient dependency that requires javax.servlet:servlet-api:2.5, but you have defined javax.servlet:servlet-api:2.4
You can either switch from javax.servlet:servlet-api:2.4 to javax.servlet:servlet-api:2.5 or add another exclusion for the javax.servlet:servlet-api:2.5 dependency. Use mvn dependency:list to find out which dependency provides the transient dependency.
Then there's another warning
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-war-plugin is missing. @ com.acme:acme-webapp:[unknown-version], /Users/staz/blossomproj/acme/acme-webapp/pom.xml, line 35, column 15

Solution 2
Blossom 3.0.6 was released yesterday to make it easier to use Spring java config. With that BlossomModuleSupport got new methods to initialize the application context and servlets using configuration classes. These are the methods that can't be found which breaks compilation.
With that the archetype snapshot version you're using was updated to generate a project that uses Spring java config, and hence these new methods.
So, you need to use 3.0.6 with the archetype and all should be fine.
