Jose commented on MGWT-263:
---------------------------
I have the same problem. I'm trying to use the new
scanRemoteServiceRelativePathAnnotation option but I get this error. I tried
setting the plugin like this:
<execution>
<id>mergewebxml</id>
<phase>process-classes</phase>
<goals>
<goal>mergewebxml</goal>
</goals>
</execution>
As in the example but it didn't work. As the documentation says "If you use
scanRemoteServiceRelativePathAnnotation you must bind this mojo to at least
compile phase" I tried setting it like this:
<execution>
<id>mergewebxml</id>
<phase>compile</phase>
<goals>
<goal>mergewebxml</goal>
</goals>
</execution>
But the result is the same.
