POM - Forcing JDK version

[Jo Support]

hi,

i'm trying to force the use of jdk 1.5 in compile time, writing this into my
pom:

            <plugin>
              <artifactId>maven-compiler-plugin</artifactId>
              <configuration>
                <fork>false</fork>
                <compilerVersion>1.5</compilerVersion>
              </configuration>
            </plugin>

but i still have this error:

 for-each loops are not supported in -source 1.3 (try -source 1.5 to enable
for-each loops)

any suggestion?
thank you very much
