【问题描述】：

几天前，我第一次设置了我的 Eclipse 以使用 JavaFX。 Eclipse 已经在我的计算机上设置了几个月，并且在我的计算机上运行没有任何问题。今天我尝试启动 Eclipse，但无法启动。日志文件中的第一个异常如下。完整日志文件位于：https://pastebin.com/NKLgdfhG

有什么想法吗？

我不明白这有什么相关性。这是一个关于 2016 年修复的真正古老的 eclipse 错误的讨论的链接？
根据您的报错信息“Error retrieving proposal text”，因此您可以尝试查找任何相关的错误以找出可能导致此错误的原因，例如插件更新。
这看起来更像是错误487268，但不久前又修复了。

【解决方案1】：

提到的日志条目发生在 2018 年 9 月。最后的条目插入到日志的末尾，而不是开头。

可能是在 2019 年 4 月 8 日至 13 日期间在您的系统上完成的从 Java 8 升级到 11 导致了问题（Java 11 不再包含 JavaFX）：

!SESSION 2019-04-08 20:31:32.915 -----------------------------------------------
eclipse.buildId=4.7.1.M20171009-0410
java.version=1.8.0_161

[...]

!SESSION 2019-04-13 00:34:34.112 -----------------------------------------------
eclipse.buildId=4.7.1.M20171009-0410
java.version=11.0.2

Running Eclipse with Java 8 应该可以解决您的问题。如果你想用 Java 11 运行 Eclipse，你必须先upgrade Eclipse（你落后了四个版本）。
