Building jaspersoft studio with maven

[jonc]

I downloaded the sources for JasperSoft Studio CE 6.13_ce from https://github.com/TIBCOSoftware/jaspersoft-studio-ce, unpacked it, and then:

$ cd aggregator$ mvn clean package

Unforturnately, this eventually fails with:

[ERROR] The build could not read 2 projects -> [Help 1][ERROR]   [ERROR]   The project com.jaspersoft.studio.community-edition:plugins:6.13.0.final (/home/jonc/work/jaspersoft-studio-ce/aggregator/plugins/pom.xml) has 3 errors[ERROR]     Child module /home/jonc/work/jaspersoft-studio-ce/aggregator/plugins/../../net.sf.jasperreports of /home/jonc/work/jaspersoft-studio-ce/aggregator/plugins/pom.xml does not exist[ERROR]     Child module /home/jonc/work/jaspersoft-studio-ce/aggregator/plugins/../../net.sf.jasperreports.doc of /home/jonc/work/jaspersoft-studio-ce/aggregator/plugins/pom.xml does not exist[ERROR]     Child module /home/jonc/work/jaspersoft-studio-ce/aggregator/plugins/../../net.sf.jasperreports.samples of /home/jonc/work/jaspersoft-studio-ce/aggregator/plugins/pom.xml does not exist

Sure enough, when I look at the unpackaged sources on the top directory, the modules: net.sf.jasperreports, net.sf.jasperreports.doc and net.sf.jasperreports.samples do not exist in the tar.gz file, nor on the github project page.

Where are the missing sources?
