Description

In a Maven Java project with a POM like this:

 
...

<plugin>
	<groupId>org.apache.cxf</groupId>
	<artifactId>cxf-xjc-plugin</artifactId>
	<version>2.6.2</version>
	<executions>
		<execution>
			<id>generate-sources</id>
			<phase>generate-sources</phase>
			<goals>
				<goal>xsdtojava</goal>
			</goals>
			<configuration>
				<sourceRoot>${basedir}/target/generated/src/main/java</sourceRoot>
				<xsdOptions>
					<xsdOption>
						<xsd>classpath:/path/to/xsd/document.xsd</xsd>
						<packagename>org.company.package.whatever</packagename>
					</xsdOption>
				</xsdOptions>
			</configuration>
		</execution>
	</executions>
</plugin>

...

The execution of Maven goal fails with exceptions like this:
