Question 1

How to set up nvim-java for a Spring Boot project?

Accepted Answer

Install nvim-java via your package manager, ensure the spring_boot_tools extension is enabled in setup, and it will automatically load Spring Boot support from JDTLS. Use commands like JavaRunnerRunMain to run applications.

Question 2

Does nvim-java support Maven and Gradle?

Accepted Answer

Yes, nvim-java works with both Maven and Gradle projects through JDTLS integration, as indicated by the badges in the README. It handles build configurations and classpaths automatically.

Question 3

nvim-java vs nvim-jdtls: which should I use?

Accepted Answer

nvim-java offers a more integrated, out-of-the-box experience with pre-configured extensions for testing and debugging, while nvim-jdtls is lighter and better for users who prefer manual, customizable setup without extra features.

Question 4

How to debug a Java test in Neovim with nvim-java?

Accepted Answer

Use commands like JavaTestDebugCurrentMethod or JavaTestDebugCurrentClass, which trigger nvim-dap sessions with breakpoints. The plugin automatically configures debug adapters and displays results in a log viewer.

Question 5

What are the system requirements for nvim-java?

Accepted Answer

Requires Neovim 0.11.5+ and a JDK installation (auto-install is supported). It also depends on external JDTLS servers and extensions, which can add 500MB+ of disk space and increase memory usage during operation.

Question 6

Can I use nvim-java with other Neovim plugins?

Accepted Answer

Yes, but careful configuration is needed to avoid conflicts, especially with other LSP or debug plugins. The README warns about checking for nvim-jdtls conflicts and recommends using it as the primary Java solution.
