After reviewing this again I found out that the problem is caused by the direct calling of javadoc's jar goal - note that this is specific to cdbs, antlr4 relies on dh and calls the 3 goals "package javadoc:jar javadoc:aggregate" together, which causes generate-sources to be run before both javadoc goals.
When direct calling a goal, maven won't have a phase/lifecycle associated to it, thus it won't activate any other plugins except for the ones in the command line. For antlr3 this causes a problem because javadoc:jar won't be able to add the generated sources paths from antlr to javadoc's option 'sourcepath' as well as fail to properly accounting for the org.antlr.gunit.swingui.parsers package. Without the antlr3:antlr goal, javadoc:jar will set sourcepath as '/build/antlr3/antlr3-3.5.2/gunit/src/main/java', while if the antlr3:antlr goal is run before javadoc's goals the sourcepath is set as '/build/antlr3/antlr3-3.5.2/gunit/src/main/java:/build/antlr3/antlr3-3.5.2/gunit/target/generated-sources/antlr3' And easy fix is to add generate-sources to the DEB_MAVEN_DOC_TARGET in debian/rules, as such: -DEB_MAVEN_DOC_TARGET := javadoc:jar javadoc:aggregate +DEB_MAVEN_DOC_TARGET := generate-sources javadoc:jar javadoc:aggregate thanks -- Tiago Stürmer Daitx Software Engineer tiago.da...@canonical.com PGP Key: 4096R/F5B213BE (hkp://keyserver.ubuntu.com) Fingerprint = 45D0 FE5A 8109 1E91 866E 8CA4 1931 8D5E F5B2 13BE
