[rules-users] Can't build 5.5.x with Maven 3.0.4 nor 3.1.0

(sending this to user since I'm not hoping to modify anything, just want to see what's going on, debug, etc) I'm working through this command on the 5.5.x branch: droolsjbpm-build-bootstrap/script/mvn-all.sh clean install -DskipTests I started the day with Maven 3.0.3, but had to upgrade due to this error: [INFO] --- maven-enforcer-plugin:1.2:enforce (default) @ kie-parent-metadata --- [WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireMavenVersion failed with message: Detected Maven Version: 3.0.3 is not in the allowed range [3.0.4,). The maven site put me to 3.1.0. But now I'm getting this error: Exception in thread "main" java.lang.NoSuchMethodError: org.apache.maven.execution.MavenSession.getRepositorySession()Lorg/sonatype/aether/RepositorySystemSession; at org.eclipse.tycho.core.maven.utils.PluginRealmHelper.execute(PluginRealmHelper.java:86) Looking around, it appears Maven 3.1.0 is the problem: (http://dev.eclipse.org/mhonarc/lists/cdt-dev/msg26246.html) So… Can't use maven 3.0.4, and can't use 3.1.0… I guess I could look for maven 3.0.5, but this seems really odd to back port, and make things so fussy on build tools. I haven't seen mvn sensitivity like this on other projects? BTW, encountered other problems as well running mvn-all.sh against 5.5.x Links: Following link from this page: http://www.jboss.org/drools/source-code To this readme file: https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/blob/master/READ... But switched to 5.5.x branch: https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/tree/5.5.x -- Mark Bennett / LucidWorks: Search & Big Data / mark.bennett(a)lucidworks.com Office: 408-898-4201 / Telecommute: 408-733-0387 / Cell: 408-829-6513
