Eclipse无法加载javadoc(“< class name>的未知javadoc格式") [英] Eclipse cannot load javadoc ("Unknown javadoc format for <class name>")

问题描述

每当我尝试从Java库中加载Javadoc(在本例中为String类)时，都会引发Eclipse异常.但是，如果我尝试悬停加载我自己编写的javadoc，它就可以正常工作！

The exception Eclipse is raising every time I try to load javadoc (in this case, for the String class) from the Java library is pasted below. However, if I try to hover-to-load javadoc I've written myself, it works fine!

这个问题一夜之间就变成了现实，所以我很惊讶-人们可能会说-为什么会发生这种事情.

This issue sort-of became a reality overnight, so I'm quite flabbergasted - one might say - as to why it is happening.

我尝试过:

• 更新日食
• 切换工作区
• 重新安装Java
• 设置似乎已正确配置(我已验证eclipse中的设置，没关系)

• Updating eclipse
• Switching workspace
• Reinstalling java
• The settings appear to be configured correctly (I validated the settings in eclipse, and it was a-OK)

没有一个起作用.

推荐答案

转到:

 Window -> Preferences -> Java -> Installed JREs

删除对JRE的引用并添加JDK.

Removing the reference to the JRE and add JDK instead.
