This commit changes AbstractWebMvcEndpointHandlerMapping to
be a MatchableHandlerMapping. Additionally, EndpointRequest,

For all other applications, AntPathRequestMatcher is used as

Due to gradle/gradle#5510, using a lambda for a task action breaks
up-to-date checks in certain circumstances.

This commit updates JavaPluginAction to use an inner-class in place
of a lambda for the action that it adds to JavaCompile tasks. A test
has not been added as it does not appear to be possible to reproduce
it with a TestKit-based test.

If the web application type is set via properties,
it is available only after binding. The environment needs
to be converted to the appropriate type if it does not match.
If a custom environment is set, it is not converted.

The 3.0.1 version of the Maven Javadoc Plugin contains a bug [1] that
means that a link URL must redirect otherwise it is ignored.

[1] https://issues.apache.org/jira/browse/MJAVADOC-532

The -link parameters passed into the javadoc executable are used
as-is. For example, redirects are not followed. Unlike 3.x, 2.x of the
Maven javadoc plugin does not attempt to follow redirects before links
are passed to the javadoc executable. As a result, for external links
to work, the links that we provide must be canonical and produce a
200 response when accessed.
