Question

我在一周前安装了eclipse luna并且每天都在工作，直到javadoc昨天破了。

当我将鼠标悬停在类或方法上时，弹出窗口会显示正确的尺寸，但它是空白的。

这个问题发生在我编写的类中，来自maven依赖项的类和来自jdk的类（如String）。

我重新启动了eclipse，计算机，它仍然无效。

我没有发现任何可能造成这种情况的不同之处。

我查看了构建路径，每个jar都有源路径和javadoc路径。

javadoc视图也是空的。

我不知道该怎么办。没有javadoc徘徊，我无法工作。

编辑：在错误视图中，我看到第一次尝试悬停时，我在“org.eclipse.jdt.ui”上收到内部错误：

编辑2：它仍然不起作用！

我卸载了eclipse并重新安装了一个新的，我擦了工作区，没有任何变化。

问题出在@Pavel Horal所说的那样您应该将浏览器切换到另一个，默认浏览器是IE，修改eclipse.ini文件eclipse.org/swt/faq.php#browserspecifydefault

或只是添加

-Dorg.eclipse.swt.browser.DefaultType = Mozilla浏览器

在eclipse.ini文件的末尾。

或者，如果您对eclipse的UI界面更熟悉，可以使用此帮助更改默认浏览器HELP。
