#174 Building fails on JDK < 8 because of -Xdoclint:none flag to Maven Javadoc plugin

[Bob Hogg]

Building htmlcleaner 2.16 from source requires JDK 8 and fails on any earlier version. The reason is the presence of the -Xdoclint:none flag in the Maven Javadoc plugin.

With it, building with OpenJDK 7 fails like so:

[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------

[ERROR] Exit code: 1 - javadoc: error - invalid flag: -Xdoclint:none

See https://stackoverflow.com/questions/27728733/javadoc-error-invalid-flag-xdoclintnone-when-i-use-java-7-but-it-works-i for more information. A suggested fix there is to check the JDK version using a Maven profile and either include that flag or not, depending on version.

Thanks!

As Java 7 is no longer supported I guess this is no longer so important.
