代码完成已停止为“ Java Extension Pack”工作”>

Question

我目前正在使用Java Extension Pack for VS Code在Java项目上工作。因此，插件已经运行了三周，现在自动完成决定无缘无故停止。

在'输出'选项卡中，我看到以下错误：

这里发生了什么，我能做些什么来解决它？

我目前正在使用Java扩展包VS Code开发Java项目。因此，插件已经运行了三周，现在自动完成功能已决定无故停止。看起来...

Answer 1

最新版本的“ Red Hat对Java（TM）的语言支持”扩展名会引发错误并中断代码的完成。

Answer 2

这似乎是最新的“ Red Hat最新的Java语言支持”（C0）和“ Visual Studio IntelliCode”扩展（C0）之间的不兼容。

Answer 3

我自己卸载了vscode中的Java Extension Pack，并单独重新安装了“ Red Hat对Java（TM）的语言支持”，这对我有用。还要在此之前清除工作空间目录，所以我不确定这是否对您有所帮助（仅清理工作空间目录并重新安装扩展包对我来说不起作用）

Answer 4

我看到今天早上发布了新版本。我已经安装了它，问题现在解决了。
