I recently ran into some problems with java development.
|
||
|
|
One problem was neovim specific but the other was an issue with gradle.
|
||
|
|
I wanted to document these in case any one else has similar problems as it took me a little bit of time to figure out.

## Problem 1: jdtls exiting with status code 13
|
||
|
|
|
||
|
|
I use jdtls through Mason with the built in nvim LSP and was recently having an issue where jdtls would immediately crash when opening a file.
|
||
|
|
The solution to this problem was just deleting the cache for jdtls:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
rm ~/.cache/jdtls
|
||
|
|
```
|
||
|
|
|
||
|
|
**Edit 05/14/2024**: This also solves the problem of jdtls not attaching on neovim startup.
|
||
|
|
May solve other problems as well, so should be first thing to try if jdtls isn't working.

## Problem 2: Could not set executable permissions for .gradle
|
||
|
|
|
||
|
|
When attempting to build with a gradlew script I was running into the following error:
|
||
|
|
|
||
|
|
*Could not set executable permissions for: ~/.gradle/wrapper/dists/gradle-7.6-bin/9l9tetv7ltxvx3i8an4pb86ye/gradle-7.6/bin/gradle*
|
||
|
|
|
||
|
|
After spending some time trying to find a solution, I found a suggestion of setting an environment variable:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
export JAVA_TOOL_OPTIONS="-Djdk.lang.Process.launchMechanism=vfork"
|
||
|
|
```
|
||
|
|
|
||
|
|
The above environment variable was all I needed and the gradle script was able to assemble the project successfully.
|
||
|
|
Hopefully this is helpful to someone!
