[ERROR] Could not retrieve the last modification timestamp for the URI [https://somehost/some/service?wsdl] from the HTTP URL connection. The [Last-Modified] header was probably not set correctly.

My bet. Thanks for a prompt reply. Indeed the problem is with the WSDL itself and I have to tweak a local copy to make it JAXB friendly anyway. I was somehow misled by the ERROR message but the plugin works perfectly fine!

how you make JAXB friendly copy, I am facing the same issue and unable to resolve it.

I have the same problem. Did you solve it?

@Marina879 I solved the problem using the 0.11.0 version of the plugin :

		<plugin>
		    <groupId>org.jvnet.jaxb2.maven2</groupId>
		    <artifactId>maven-jaxb2-plugin</artifactId>
		    <version>0.11.0</version>
		    <executions>
		        <execution>
		            <goals>
		                <goal>generate</goal>
		            </goals>
		        </execution>
		    </executions>
		    <configuration>
		        <schemaLanguage>WSDL</schemaLanguage>
		        <generatePackage>AccPaymentGateway.wsdl</generatePackage>
		        <schemas>
		            <schema>
		            	<url>(your schema URL here)</url>
		            </schema>
		        </schemas>
		    </configuration>
		</plugin>

@jcatino That solved the problem for me too. On 0.14.0 version, I found it was success but show error log .
