Ranjan George commented on MNG-3086: ------------------------------------ We are facing the same problem with ranges when we upgraded from 2.0.4 to 2.0.7. The former seems to be working fine. Our pom(s) are organized in the following manner: /ProjectA /pom.xml /ProjectB /pom.xml /pom.xml Project A has the following dependency: <dependency> <groupId>dom4j</groupId> <artifactId>dom4j</artifactId> <version>[1.6,)</version> <scope>compile</scope> </dependency> <dependency> <groupId>xerces</groupId> <artifactId>xercesImpl</artifactId> <version>[2.6.2,)</version> <scope>compile</scope> </dependency> Project B's pom.xml specifies a dependency on Project A. When I have a dependency declared in Project A with a range specified for the version. For eg. [1.6,), I get the exception shown above while compiling of installing ProjectB with Maven 2.0.7. With maven 2.0.6 I get an unable to resolve dependency error showing the below error: Missing: ---------- 1) xerces:xercesImpl:jar:RELEASE Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=xerces -DartifactId=xercesImpl \ -Dversion=RELEASE -Dpackaging=jar -Dfile=/path/to/file Path to dependency: 1) ProjectB 2) commons-configuration:commons-configuration:jar:1.2 3) xerces:xercesImpl:jar:RELEASE 2) dom4j:dom4j:jar:RELEASE Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=dom4j -DartifactId=dom4j \ -Dversion=RELEASE -Dpackaging=jar -Dfile=/path/to/file Path to dependency: 1) ProjectB 2) commons-configuration:commons-configuration:jar:1.2 3) dom4j:dom4j:jar:RELEASE Looks like a dependency resolution problem when evaluating ranges. In commons-configuration the dependency for dom4j & xerces in its pom.xml seems to be as follows: <dependency> <groupId>dom4j</groupId> <artifactId>dom4j</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>xerces</groupId> <artifactId>xerces</artifactId> <version>2.2.1</version> </dependency> > NullPointerException in ResolutionNode.getTrail(ResolutionNode.java:136) > ------------------------------------------------------------------------ > > Key: MNG-3086 > URL: http://jira.codehaus.org/browse/MNG-3086 > Project: Maven 2 > Issue Type: Bug > Components: Errors > Affects Versions: 2.0.7 > Reporter: Thomas Leonard > > After upgrading from 2.0.6 to 2.0.7, our build fails with: > [INFO] [resources:resources] > [INFO] Using default encoding to copy filtered resources. > [INFO] > ------------------------------------------------------------------------ > [ERROR] FATAL ERROR > [INFO] > ------------------------------------------------------------------------ > [INFO] null > [INFO] > ------------------------------------------------------------------------ > [INFO] Trace > java.lang.NullPointerException > at > org.apache.maven.artifact.resolver.ResolutionNode.getTrail(ResolutionNode.java:136) > at > org.apache.maven.artifact.resolver.ResolutionNode.filterTrail(ResolutionNode.java:211) > at > org.apache.maven.artifact.resolver.DefaultArtifactCollector.collect(DefaultArtifactCollector.java:89) > at > org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolveTransitively(DefaultArtifactResolver.java:284) > at > org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolveTransitively(DefaultArtifactResolver.java:272) > at > org.apache.maven.plugin.DefaultPluginManager.resolveTransitiveDependencies(DefaultPluginManager.java:1238) > at > org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:397) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:539) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalWithLifecycle(DefaultLifecycleExecutor.java:480) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal(DefaultLifecycleExecutor.java:459) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures(DefaultLifecycleExecutor.java:311) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments(DefaultLifecycleExecutor.java:278) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifecycleExecutor.java:143) > at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:334) > at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:125) > at org.apache.maven.cli.MavenCli.main(MavenCli.java:280) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > at java.lang.reflect.Method.invoke(Method.java:585) > at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java:315) > at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) > at > org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:430) > at org.codehaus.classworlds.Launcher.main(Launcher.java:375) > Thanks, -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
