I would have thought that maven would complain when provided versions were not compatible with requested versions. I'm working on maven-ant-tasks which lists: <dependency> <groupId>org.apache.ant</groupId> <artifactId>ant</artifactId> <version>1.8.0</version> </dependency> But the build didn't complain at all with ant 1.7.1 installed, until the compile failed because an ant 1.8 feature was used. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane orion@xxxxxxxxxxxxx Boulder, CO 80301 http://www.cora.nwra.com -- java-devel mailing list java-devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/java-devel
