Eclipse (STS) 上的装饰计算错误

Question

当我尝试在 STS 上打开 xml 文件时出现错误。

内容如下：

发生内部错误：“装饰计算”。 org/springframework/tooling/boot/ls/xml/XMLRootElementContentDescriber2$QualifiedElement

当我查看元数据中的日志时，输出了以下错误消息。

问题是什么？ STS版本为4.3.2.

Answer 1

我的解决方案是通过转到 Windows - 首选项 - 常规 - 外观 - 标签装饰并取消选中 Javascript 覆盖功能指示器来删除 javascript 标签装饰

另一种可能的解决方案可能是运行使用 -clean 选项的 eclipse :

在 Windows 上：

eclipse.exe -clean

这将清除您的插件缓存，这可能会解决您的问题
