NullPointerException starting roo 1.0.2 via command line

[watcher]

I have an existing roo project that is now causing issue when I start via command line.

NullPointerException at org.springframework.roo.project.Dependency.<init>(Dependency.java:117)

roo version 1.0.2
jdk 1.6_21
mvn 2.2.1

any ideas please?

[watcher]

I had a dependency that was excluding spring

<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-core</artifactId>
<version>${camel-version}</version>
<exclusions>
<exclusion>
<artifactId>org.springframework</artifactId>
</exclusion>
</exclusions>
</dependency>

DOH!
