Hello and thanks for the report,

I agree this is a bug in Debian's version of Netbeans. Currently we can
only support Java SE features though, basically the same technologies
listed on Netbeans' official download page:

https://netbeans.org/downloads/

However I consider the severity of this bug more than "wishlist" because
I haven't found a way to work around it e.g. by installing one of the
HTML5 plugins.

The reason for this exception is most likely the disabled html.parser
module. For building it we need at least another build-dependency,
validator.nu HTML parser from https://about.validator.nu/htmlparser/.
There is a similar named package in Debian called libhtmlparser-java but
the code looks different to me.

The same applies for Javascript. All Javascript modules have been
disabled because we can't build them from source at the present time.
For instance they require the Nashorn JavaScript Engine, a Java8 feature.

I would like to enable and support all HTML5 and Javascript modules but
due to missing dependencies this is not feasible at the moment.

I haven't tried it myself yet but working with PHP only files should be
possible if you install the PHP plugin.

Regards,

Markus
