> Key: MDEP-364
> URL: https://issues.apache.org/jira/browse/MDEP-364
> Project: Maven Dependency Plugin
> Issue Type: Bug
> Components: tree
> Affects Versions: 2.4
> Environment: Apache Maven 3.0.4 (r1232337; 2012-01-17 08:44:56+0000)
> Maven home: /opt/app/eti/tools/apache-maven-3.0.4
> Java version: 1.6.0_15, vendor: Sun Microsystems Inc.
> Default locale: en_US, platform encoding: ANSI_X3.4-1968
> OS name: "linux", version: "2.6.9-42.0.8.elsmp", arch: "amd64", family: "unix"
> Reporter: Sergei S. Ivanov

> We have bound execution of _dependency:tree_ to the _verify_ phase in the parent POM for all of our projects. That way, maven always dumps a complete tree of dependencies for a project after it's been fully packaged and before it's installed/deployed.
> The plugin set-up looks like this:
> {code:lang=xml}
> <plugin>
> <inherited>true</inherited>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-dependency-plugin</artifactId>
> <version>2.4</version>
> <executions>
> <execution>
> <!-- Output dependency tree at the end of build process -->
> <id>display-dependency-tree</id>
> <phase>verify</phase>
> <goals>
> <goal>tree</goal>
> </goals>
> </execution>
> </executions>
> </plugin>
> {code}
> Today it failed sporadically with an NPE during a routine CI build in Jenkins.
> Maven options for Jenkins:
