Javadoc错误-java.lang.reflect.InvocationTargetException [英] Javadoc error - java.lang.reflect.InvocationTargetException

问题描述

我正在尝试从yDoc库生成uml图.它基本上使用Javadoc来解析Java源文件.但是，当我尝试从终端(OS X)执行命令时，出现以下错误:

I am trying to generate the uml diagram from yDoc library. It basically uses Javadoc to parse tha Java source files. However, when I am trying to execute the command from terminal(OS X), I am getting following error:

javadoc: error - In doclet class ydoc.doclets.YStandard,  method start has thrown  
an exception  
java.lang.reflect.InvocationTargetException java.lang.NoSuchMethodError:

我运行了以下执行命令:

I ran the following execution command:

javadoc @doc/examples/options.sample.linux <Java file path>

从Eclipse IDE尝试时，我也遇到相同的错误.

I am also getting same error when trying from Eclipse IDE.

推荐答案

@codeblues和@Grant M，我刚刚注意到了这个问题.我是该博客文章 Grant M的作者提及.我只是再次尝试了我的指令，就可以按预期获得带有UML图的Javadoc.

@codeblues and @Grant M, I just noticed this question. I am the author of that blog post Grant M mentioned. I just tried my instructions again, I am getting Javadoc with UML diagram as expected.

在我看来，这听起来像JDK(和JavaDoc)与Ydoc.jar之间的版本不匹配.与Javadoc相关的类位于jdk \ lib文件夹中的一个名为tools.jar的jar中.您可能要检查类路径，以查看它是否包含正确的JDK.您可能可以尝试在* nix上使用哪个javadoc(或在Win 7+上使用"where javadoc"找出使用的JDK位置).

To me, this sounds like a version mismatch between JDK (and JavaDoc)and Ydoc.jar. Javadoc related classes are in a jar called tools.jar in jdk\lib folder. You may want to check your classpath to see if it includes the right JDK. You can probably try which javadoc on *nix (or "where javadoc" on Win 7+ to find out the JDK location used).

在您的异常中提及未知源"似乎表明您指向的是JRE而不是JDK?此外，请参见此.

The mention "Unknown source' in your exception seems to indicate you are pointing to JRE instead of JDK?? Also, see this Stackoverflow post about "(unknown source)" in Java Exceptions.

我希望您能使它正常工作，以查看UML跳入Javadoc！

I hope you can get this to work, to see the UMLs jump into your Javadoc!
