NPE when resolving the version of a dependency
----------------------------------------------
Key: MDEP-67
URL: http://jira.codehaus.org/browse/MDEP-67
Project: Maven 2.x Dependency Plugin
Issue Type: Bug
Affects Versions: 2.0-alpha-1
Reporter: Stephane Nicoll
Assigned To: Brian Fox
In my project I have the following dependency
{noformat}
<dependency>
<groupId>com.foo.shared.bar</groupId>
<artifactId>foo-bar</artifactId>
<version>5.8.3</version>
<classifier>obfuscated</classifier>
</dependency>
{noformat}
I try to get the sources without specifying the version so I have the following
config:
{noformat}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy</id>
<phase>compile</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>com.foo.shared.bar</groupId>
<artifactId>foo-bar</artifactId>
<type>java-source</type>
<outputDirectory>${project.build.directory}/foo-sources</outputDirectory>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
{noformat}
And I got this
{noformat}
java.lang.NullPointerException
