Neovim: How to Use Java Debugging

Let's debug java applications with Neovim quickly and efficiently! In the video, I presented my approach to debugging spring applications in Neovim.

Really useful video! Well done 👍

[@tobiasvaldez5206]

Thanks!, this was what i was searching for

[@rddavies]

Very impressive!

[@eygs493]

it worked right outt of box, thank you, lol

[@Amin-ze2hr]

Thanks for the video. Do you have any idea how we should set it up for non-springboot projects? (projects that run via war file in tomcat)

[@marshzhou7794]

it's cool

[@orbistabula5922]

Привет. Было бы круто увидеть полную настройку nvim под фронтэнд разработку: React, typescript, NodeJS, prettier... 👍👍

[@itachicodes2506]

Can you do a new 2024 update for Java debugging please

[@m3kbeatz]

Can u set values in debug mode?

[@IvanByteTV]

Sure, as in a normal debug mode

[@micro4el224]

java.....

[@pedrolobo9835]

Hi, we have good stuff in this video! Can you please test something for me? Try the :lua require'dap'.step_into() command at some System.out.println() line. What happened?

[@IvanByteTV]

The debugger will show nothing, to continue press F5(dap.continue) This happens because System.out.println is inside of compiled JDK class. In IDEs, such as IntelliJ Idea (I've used for 8 years) there is a decompiler for that reason. Actually, I think it's possible to configure www.benf.org/other/cfr/ Or download sources and configure them for your debug session. But it's a quite rare case in my practice, for the deep debugging I would opt for IntelliJ Idea (even with the free community version you can use decompiler).

[@pedrolobo9835]

@@IvanByteTV Thanks for the reply, but I'm not sure about that, because we can use :lua vim.lsp.buf.definition() to see what is inside the System.out.println() without decompilers.

[@IvanByteTV]

@@pedrolobo9835 Oh You're right. If there are sources, it's possible to check definitions. Do you have any ideas to share on how to implement it?
