pom.xml of jboss-ejb3-build specifies multiple dependency versions for the same artifact(s) ------------------------------------------------------------------------------------------- Key: EJBTHREE-1957 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1957 Project: EJB 3.0 Issue Type: Bug Components: build Reporter: jaikiran pai Assignee: jaikiran pai While trying out Maven-3 (alpha-4) against our project, Maven-3 showed up that our pom.xml of the jboss-ejb3-build has duplicate dependency elements with different versions for the same artifact(s): ... <version.org.jboss.common.core>2.2.14.GA</version.org.jboss.common.core> ... <version.org.jboss.reflect>2.0.2.GA</version.org.jboss.reflect> ... <dependency> <groupId>org.jboss</groupId> <artifactId>jboss-common-core</artifactId> <version>2.2.5.GA</version> </dependency> ... <dependency> <groupId>org.jboss</groupId> <artifactId>jboss-reflect</artifactId> <version>2.0.0.CR1</version> </dependency> ... <!-- JBoss Common Core --> <dependency> <groupId>org.jboss</groupId> <artifactId>jboss-common-core</artifactId> <version>${version.org.jboss.common.core}</version> </dependency> <!-- JBoss Reflect --> <dependency> <groupId>org.jboss</groupId> <artifactId>jboss-reflect</artifactId> <version>${version.org.jboss.reflect}</version> </dependency> Notice that the pom declares dependency on jboss-common-core for 2 different versions (2.2.5.GA and 2.2.14.GA). Same is the case with jboss-reflect. Maven-2 doesn't show up this as an error (it should have), but Maven-3 rightly shows this as an error and fails to build: [ERROR] The build could not read 1 project -> [Help 1] [ERROR] The project org.jboss.ejb3:jboss-ejb3-build:1.0.8-SNAPSHOT (/home/jpai/business/jboss/wc/jbossas/projects/ejb3/trunk/build/pom.xml) has 2 errors [ERROR] 'dependencyManagement.dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: org.jboss:jboss-common-core:jar -> version 2.2.5.GA vs ${version.org.jboss.common.core} [ERROR] 'dependencyManagement.dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: org.jboss:jboss-reflect:jar -> version 2.0.0.CR1 vs ${version.org.jboss.reflect} [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
