Generate RCP

Hello everybody!
I’am trying to generate capella RCP from the source code using eclipse 4.7.3a (created with Oomphsetup) in ubuntu 18.04 but when I run the export wizard from the capella capella.product in org.polarsys.capella.rcp I get:
Processing inclusion from feature org.eclipse.equinox.executable: Unable to find plug-in: org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.551.v20 171108-1834. Please check the error log for more details.
I tried to add Delta Packs with no succes. There is an special way to generate the RCP?
Thank you in advance

The official build uses maven. Install maven, then go to the capella top directory and run:
mvn -f releng/plugins/org.polarsys.capella.targets/pom.xml clean verify
(This will build a targetplatform .target file)
and now run
mvn clean verify
which builds the product.
