Thanks Marc. The plugin config change works. The license replaced with ASF 2. 

I did not setup a copyright config in IntelliJ so when I copied the code over from another
project it left the copyright as is.

I now have the build and test running but need to figure out the rendered HTML differences
because the tests do not match what pegdown generated. Looking into it now.

> The parsing time for Markdown documents can take very long and hang site generation when
e.g. long tables are being generated.
> The author of pegdown has marked the pegdown project deprecated since 2016-12-14 [pegdown.org|https://github.com/sirthias/pegdown/]
and advises to switch to [flexmark-java|https://github.com/vsch/flexmark-java].
> {quote}
> The project is essentially unmaintained with tickets piling up and crucial bugs not being
fixed.
> pegdown's parsing performance isn't great. In some cases of pathological input runtime
can even become exponential, which means that the parser either appears to "hang" completely
or abort processing after a time-out.
> {quote}
> Since the parsing timeout was increased in DOXIA-498 it is now possible to "hang" the
site creation with a longer table like the one in this example.
> In case this sample is rendered using version 3.3 of the maven site
