build error with missing Drools

[vipup]

Hello,

i just try to build JBPM from sources.

With http://sourceforge.net/projects/jbpm/files/jBPM%205/jbpm-5.0-Final/jbpm-5.0.0-src.zip/download  i get the error:

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR

[INFO] Failed to resolve artifact.
Missing:
----------
1) org.drools:drools-api:jar:5.2.0.M1

Then, install it using the command:
mvn install:install-file -DgroupId=org.drools -DartifactId=drools-api -Dversion=5.2.0.M1 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=org.drools -DartifactId=drools-api -Dversion=5.2.0.M1 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

what is very similar with Activiti build:
