I recently upgraded my development environment from Java 7 to Java 8, which now detects a large number of previously unknown javadoc problems.
By default, Ant (called through Eclipse Mars) limits its warnings (and I make mistakes) to 100:

Is there any parameter to get Ant to display all javadoc warnings instead of limiting to 100?
I tried using the parameter -Xmaxwarns 1000with an element compilerarg, but it seems that the current version of Ant in Eclipse Mars (Ant 1.9.4) javadoc task does not support the element compilerarg(only supported in javac task )
<target name="javadoc" depends="clean" description="Generate the API documentation.">
<mkdir dir="${build.folder}" />
<mkdir dir="${docs.folder}" />
<javadoc destdir="${docs.folder}/api" author="true" version="true" use="true" windowtitle="${documentation.title}">
<compilerarg value="-Xmaxerrs 1000 -Xmaxwarns 1000" />
<classpath>
...

Java 8 javadoc ( Java 7 b100):
C:\>javadoc -X
-Xmaxerrs <number> Set the maximum number of errors to print
-Xmaxwarns <number> Set the maximum number of warnings to print
Provided by standard doclet:
-Xdocrootparent <url> Replaces all appearances of @docRoot followed
by /.. in doc comments with <url>
-Xdoclint Enable recommended checks for problems in javadoc comments
-Xdoclint:(all|none|[-]<group>)
Enable or disable specific checks for problems in javadoc comments,
where <group> is one of accessibility, html, missing, reference, or syntax.
These options are non-standard and subject to change without notice.
