无法使用 LspInstall 让 jdtls 在 neovim 中工作

Question

我目前正在尝试让 jdtls 在我的 neovim 配置中工作，但每次我打开 java 文件时它都无法正常启动

lsp.log 的内容如下：

[START][2023-04-20 14:25:54] LSP logging initiated

• 我尝试将我的jdk版本从最新更改为17
• 我尝试手动安装 jdtls 并在没有 lsp 和 mason 插件的情况下配置它

Answer 1

看起来 jdtls 在启动过程中崩溃了。

我在部分清理环境后遇到了这个问题。当 Jdtls 尝试加载已删除的 jar 并抛出上述错误时，它会崩溃。我通过清除 eclipse 缓存修复了它（

'-data', workspace_folder

输入 jdtls 命令就是位置）

对于进一步的根本原因，由于崩溃的是 jdtls 而不是 lsp，因此您需要在启动期间通过传入

'-Xlog::file=' .. home .. '/logs/test.log', '-verbose'

来获取 java 的日志输出。
