Error initializing enunciate - generate step error - maven

Question

I have configured my REST/Spring/Jersey project to generate documentation for APIs using enunciate.
The relevant changes in my pom.xml are
<plugin>
<groupId>org.codehaus.enunciate</groupId>
<artifactId>maven-enunciate-spring-plugin</artifactId>
<version>1.28</version>
<configuration>
<generateDir>${project.build.directory}/enunciate-generate</generateDir>
<configFile>enunciate.xml</configFile>
<exports>
<jaxws.client.library.binaries>client.jar</jaxws.client.library.binaries>
</exports>
</configuration>
<executions>
<execution>
<goals>
<goal>assemble</goal>
</goals>
</execution>
</executions>
</plugin>
.....
<dependency>
<groupId>org.codehaus.enunciate</groupId>
<artifactId>maven-enunciate-spring-plugin</artifactId>
<version>1.28</version>
</dependency>
My enunciate.xml is as follows
<?xml version="1.0"?>
<enunciate xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://enunciate.codehaus.org/schemas/enunciate-1.28.xsd">
<api-classes>
<include pattern="com.xxx.rest.*"/>
</api-classes>
<modules>
<docs docsDir="api" title="REST WebServices API"/>
<spring-app>
<war mergeWebXML="war/WEB-INF/web.xml"/>
<springImport file="war/WEB-INF/applicationContext-jdbc.xml"/>
</spring-app>
</modules>
</enunciate>
When I run my maven project I get the following error initializing enunciate. As you can see the error is not very helpful. Any hints what could be wrong in my configuration.
--- maven-enunciate-spring-plugin:1.28:assemble (default) # xxx ---

Answer 1

That StringIndexOutOfBoundsException was reported and fixed here.
The "invocation of API has failed" is almost always caused by some compile failure. Maybe when you messed with your dependencies to get around the first problem, you introduced a compile failure in your code base?
