使用Ant进行编译时,增加javadoc警告的最大数量

Question

我最近将我的开发环境从Java 7升级到Java 8,现在发现了大量以前未检测到的javadoc问题.

默认情况下,Ant(通过Eclipse Mars调用)将其警告(我假设错误)限制为100:

是否有任何参数强制Ant显示所有 javadoc警告而不是限制为100？

我试图-Xmaxwarns 1000通过compilerarg元素使用参数,但似乎Eclipse Mars(Ant 1.9.4)javadoc任务中的当前Ant版本不支持该compilerarg元素(它仅在javac任务中受支持):

<!-- Generate the API documentation. -->
<target name="javadoc" depends="clean" description="Generate the API documentation.">

    <!-- Create the build directory structure used by javadoc. -->
    <mkdir dir="${build.folder}" />
    <mkdir dir="${docs.folder}" />

    <!-- Run javadoc. -->

    <javadoc destdir="${docs.folder}/api" author="true" version="true" use="true" windowtitle="${documentation.title}">

        <compilerarg value="-Xmaxerrs 1000 -Xmaxwarns 1000" />

        <classpath>

        ...

Java 8 javadoc 确实支持这些参数(Java 7 b100中添加了支持):

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.

结论: Ant javadoc任务似乎是限制因素,如果它支持该compilerarg标志,则可以调整错误和警告的限制.

如您所述,-Xmaxwarns会影响javadoc程序输出的警告数量.

-Xmaxwarns可以javadoc使用嵌套<arg>元素传递给程序:

<javadoc ...>
    <arg value="-Xmaxwarns"/>
    <arg value="200"/>
</javadoc>

在我自己的测试用例中,我能够将报告的警告增加到100以上:

[javadoc] Generating Javadoc
...
[javadoc] 112 warnings
