[Andy Seaborne <an...@apache.org>]

This is madness.

One error and nothing is produced.
One warning and maven fails the build.

And even when it's Java 1.7 source code, it breaks with a java8 compiler.

http://blog.joda.org/2014/02/turning-off-doclint-in-jdk-8-javadoc.html

To say the Jena build is comprehensive broken is an understatement.

It is ridiculously picky -

1/ <br/> ILLEGAL!

2/ all @params, @returns, @throws MUST be present.

3/ <table> without summary is illegal.

4/ ">" (which is OK to all browsers -- only "<" must be escaped)

5/ And other stuff I keep coming across.

Yes - doclint can be turned off - but -Xdoclint:none is illegal to java7 
javadoc.

The only way to preserve the build is to turn doclint off ... which 
defeats the purpose.

Which I have done in jena-parent, conditional of java8+.


BUT even then the build breaks:

A/ Mythical javadoc (merely 100 warnings)

.../jena/ontology/OntProperty.java:483: warning - @propertyDescription 
is an unknown tag.

Yes - it's unknown.  It is also NOT IN THE FILE.

.../jena/ontology/OntProperty.java:483: warning - Tags @propertyGetter, 
@propertySetter and @propertyDescription can only be used in JavaFX 
properties getters and setters.

which does not occur in the code code.


B/ ... in ARQ ...

[ERROR] Failed to execute goal 
org.apache.maven.plugins:maven-remote-resources-plugin:1.5:process 
(default) on project jena-arq: Error rendering velocity resource. 
NullPointerException -> [Help 1]
