[seam-issues] [JBoss JIRA] (SOLDER-301) Solder does not build from source: Shade plugin complains that seam-parent pom version 16 is missing (but it's in my local repo)

[ https://issues.jboss.org/browse/SOLDER-301?page=com.atlassian.jira.plugin... ] Geoffrey De Smet edited comment on SOLDER-301 at 12/6/11 9:06 AM: ------------------------------------------------------------------ @Christian Why use shaded jars in the first place? Afaik, shaded jars bring nothing but trouble: - If jar B shades jar A and both A and B end up in the same classpath (very likely in big projects that indirectly depend on A and B) and they are different versions (again likely), then the classes of the first jar on the classpath will be used at runtime (which is in practice means you don't know which one). Furthermore, the exceptions raised are unclear (NoSuchMethodError, ClassCastException: cannot cast Dog to Animal (but Dog does extend Animal), ...). - the Red Hat guys that do RPM repackaging of our projects in http://www.jpackage.org/ absolute hate shaded jars as they can't deal with them - OSGi doesn't like shaded jars. - Once JDK 8 Jigsaw is out, you won't be able to shade any more anyway. So instead of shading to create "dependency reduced pom.xml" and "shade the dependencies in the jar", can't the jar not shade those dependencies and simply depend on them in it's pom? was (Author: ge0ffrey): @Christian Why use shaded jars in the first place?
