repositories example throws NoSuchMethodError due to conflicting log4j versions ------------------------------------------------------------------------------- Key: DNA-500 URL: https://jira.jboss.org/jira/browse/DNA-500 Project: DNA Issue Type: Bug Components: Examples Affects Versions: 0.6 Environment: JBoss DNA revision 1142 java version "1.6.0_0" OpenJDK Runtime Environment (IcedTea6 1.5) (ArchLinux-1.5-5-i686) OpenJDK Server VM (build 14.0-b15, mixed mode) Reporter: torkjel hongve Assignee: Randall Hauch Fix For: 0.6 When launching the repositories example (using run.sh from target/dna-example-repositories-basic.dir/) I immediately get the following error: Exception in thread "Thread-1" java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z at org.slf4j.impl.Log4jLoggerAdapter.isTraceEnabled(Log4jLoggerAdapter.java:81) at org.jboss.dna.common.util.Logger.isTraceEnabled(Logger.java:411) at org.jboss.dna.graph.connector.map.MapRepositoryConnection.execute(MapRepositoryConnection.java etc... This is due to the lib direcotry containing both log4j-1.2.14.jar and log4j-1.2.8.jar. 1.2.14 is the correct one and contains the isTraceEnabled method, but version 1.2.8 is the one being used at runtime. "mvn dependency:tree" shows the following dependendy paths to log4j: [INFO] +- log4j:log4j:jar:1.2.14:compile [INFO] +- org.jboss.security:jbosssx-bare:jar:2.0.2.SP6:compile [INFO] | +- org.jboss.security:jboss-security-acl-impl:jar:2.0.2.SP6:compile [INFO] | | +- jboss:jboss-logging-log4j:jar:2.0.2.GA:runtime [INFO] | | | \- apache-log4j:log4j:jar:1.2.8:runtime
