Ant JavaDoc任务从自定义标记中抛出`NoClassDefFoundError`，即使类*在类路径上是*

时间：2014-11-25 22:19:35

标签： java ant classpath javadoc taglet

我遇到了JavaDoc Ant任务的问题。它给了我一个java.lang.NoClassDefFoundError的类，就我所知，它肯定在类路径上。根据{{​​3}}，当类在编译期间存在时抛出NoClassDefFoundError，但在运行时期间无法找到。 （A the documentation。）

当我删除classpath项时，它会按预期失败（许多包/符号未找到错误），而仍然给出相同的NoClassDefFoundError。为什么这个类是否在类路径上而对于taglet失败了？

细节：

它找不到的类称为com.github.xbn.io.SimpleDebugable，它在这个jar文件中：

  • Jar文件：C:\data_jeffy\programming\sandbox\z__for_git_commit_only\codelet\z_build\jar_dependencies\xbnjava-0.1.4.2-all.jar

JavaDoc Ant任务。上面的jar文件是类路径中的第一个项目。

当您从类路径中完全删除jar文件时，它会按预期失败，并出现几百package com.github.xbn.... does not exist和symbol not found个错误，这意味着classpath元素显然是“正常”。那么为什么它不适用于taglet？

现在的问题是，似乎JavaDoc正在“吞噬”这个错误。我不知道如何看到java.lang.ClassNotFoundException的痕迹。

1 个答案:

答案 0 :(得分：3)

问题是taglet路径。必须将类路径冗余地传递到主JavaDoc任务和每个自定义标记。每个标记都必须具有不同的ClassLoader，因此需要重复的类路径。

蚂蚁documentation for the taglet's "path" attribute没有明确说这是一个类路径，这让我很困惑：

  

指定taglet类的搜索路径的路径（例如/ home / taglets）。路径也可以由嵌套元素

指定
