[M2] Differences of jars between Ant's build and m2's build

Hi there, I've compared the libraries in the xwiki standard war generated by both the Ant build and by m2's build. There are numerous differences which we need to reconcile: Jars present in the m2-generated war but not present in Ant's build: ==================================================================== activation 1.1 commons validator 1.1.4 jmock 1.0.1 junit 3.8.1 logkit 1.0.1 servlet api 2.4 velocity-dep 1.4 xpp3 1.1.2a xstream 1.0.2 I don't think we need those (they were added by transitive dependencies but there are often errors in the POMs. For example the junit and jmock jars are probably because these deps did not have a "test" scope in some POM). I'll exclude those. Jars present in the Ant-generated war but not present in m2's build: ==================================================================== asm 1.5.3 asm-util 1.5.3 c3p0 0.8.4.5 cglib 2.1 clover 1.3.9 (not needed I believe in the main war) commons discovery 0.2 commons logging adapter 1.1 commons logging api 1.1 concurrent derby 10.1.3.1 ehcache 1.1 flipper hibernate-tools 2.1.3 hsqldb 1.8.0 exo services chart api 2.0 exo services chart impl 2.0 exo services commons api 2.0 exo services database impl 2.0 exo services organization impl 2.0 exo services security impl 2.0 jimi lucene 1.4.3 mysql connector java 3.1.7-bin odmg 3.0 qname 1.5.2 saaj 1.2 securityfilter 2.0 serializer 2.7.0 sl4j log4j12 1.0.1 swarmcache velocity tools 1.1 ws-common-java5 1.0.1 wsdl4j 1.5.2 xmlrpc-client 3.0 xsltc 2.7.0 None of these jars are required for compiling the classes in core/src/main/java. There are 2 possibilities: 1) some are required at runtime 2) some are extra jars that we don't need Could someone please tell me which jars fall in category 1) and which fall in category 2)? Another question: Do we need the exo jars at all (this is the standard war, not the exo one)? Version mismatch between Ant's and Maven2's builds ================================================== antlr 2.7.2 (m2) vs 2.7.5 avalon fwk 4.1.3 vs 4.1.5 commons beanutils 1.6 vs 1.7 commons digester 1.6 vs 1.7 commons fileupload 1.0 vs 1.1.1 commons pool 1.2 vs 1.1 ical4j 0.9.19 vs 0.9.19M log4j 1.2.12 vs 1.2.13 xalan 2.5.1 vs 2.7.0 xml apis 1.0.b2 vs 2.0.2 xerces impl 2.5.0 vs xerces 2.7.1 These are jars that were added by transitive dependencies (as otherwise they would have the same version). I need to know for which of them it's ok to use the version brought by transitive deps (normally all I'd say but I'd like to check).
