Guillaume Boué commented on MWAR-396:
-------------------------------------
It would be possible to check for the presence of
[{{javax.servlet.annotation.WebServlet}}|http://docs.oracle.com/javaee/7/api/javax/servlet/annotation/WebServlet.html].
This annotation was introduced in the Servlet 3.0 API and replaces the
{{<servlet>}} declaration in the {{web.xml}}. So if that class isn't in the
compile classpath of the {{MavenProject}} being built, a {{web.xml}} should be
present.
How about the possible solution? Call
{{mavenProject.getCompileClasspathElements()}}, create a new {{URLClassLoader}}
for the paths of that list and use this classloader to determine if that class
can be loaded.
> Check the existence of the web.xml based on the existence of particular
> classes
