Hi Edgard, I had the same problem. The macrodef for runmaven in buildomatic/bin/dev.xml expects a Java property maven.home. When I set it in the default_master.properties it fixed the problem. It would be good if the JasperReports-Server-CP-Source-Build-Guide.pdf would include a hint to set this property to avoid that problem. Best, Sandro Post Edited by sandro_boehme at 01/24/2012 10:08
