Eclipse（Java）无法加载工作区

Question

我第一次打开Eclipse时出现了错误信息，并告诉我检查日志。于是我检查了日志，以下是日志内容。我尝试删除.metadata文件夹，但没有解决问题。

这看起来像是由于类未找到的异常引起的。您最近是否删除或更改了任何项目的路径？ - wanderer0810

这是我第一次加载 Eclipse。 - mellowant

你正在使用Java 9和旧版本的Eclipse。要么使用Java 8，要么安装Eclipse Oxygen.1a (4.7.1a)，该版本预计今天发布。 - greg-449

@greg-449...已经发布了：请参见https://www.eclipse.org/downloads/eclipse-packages/ ;-) - howlger

Answer 1

正如有人建议的那样，最好的解决方案是安装具有对Java 9的本机支持的Eclipse 4.7.1a，无论如何，如果您拥有旧版的eclipse，您可以添加：

--add-modules=java.se.ee

在eclipse.ini文件中，在-vmargs之后添加内容，这将解决问题。
