Maven enunciate error: "String index out of range: 0"

Question

When I build my Maven project or generate my eclipse configuration using mvn eclipse:eclipse, I get the following error:

[ERROR] Failed to execute goal org.codehaus.enunciate:maven-enunciate-plugin:1.28:docs (default) on project appserver-server: Problem assembling the enunciate app. String index out of range: 0 -> [Help 1]

I have isolated the issue to a single dependency:

<dependency>
    <groupId>com.tinkerpop.blueprints</groupId>
    <artifactId>blueprints-neo4j-graph</artifactId>
    <version>2.4.0</version>
</dependency>

I need this dependency, so getting rid of it isn't an option but why is this causing an error in enunciate to appear? Is there any way to fix this?

Edit: after some further testing, the root of the problem may be from this dependency of a dependency of a dependency of a dependency of the previous dependency:

<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-library</artifactId>
    <version>2.10.4</version>
</dependency>
