You configured the assembly-plugin with some information about source/target but to configure the compiling you need to configure the compiler-plugin in the correct way.

  org.apache.maven.plugins

  2.3.1
  
    1.5
    1.5
  

Update: This should be combined with maven-enforcer-plugin to force really using of JDK 1.5 instead of only using source/target option of the javac.
