building error for servicemix on linux distribution

[Karim Hamed-abdelouahab <ka...@gmail.com>]

Hello,
I'm trying to build the servicemix on linux distribution Feodora 8.

I've installed maven version 2.0.8 and using jdk 1.5.b06.
I downloaded the source using svn in a directory.
I started with the following command:
"mvn -e -Dmaven.test.skip=true -Pstep1 install"

I've got an error during the first building process.
Here is the output in the error area:
[INFO] ------------------------------
------------------------------------------
[ERROR] BUILD ERROR
[INFO]

[INFO] Internal error in the plugin manager executing goal
'org.apache.servicemix:servicemix-build:1.0:copy': Unable to find the mojo

org/apache/servicemix/maven/plugin/legal/LegalMojo (Unsupported major.minor
version 49.0)

Please, I'm a new user (in java and no experiences in servicemix). May I ask
you do not write understandble java formule.
Thank you in advance.
