Troubleshooting
Download missing or no JAR
Why a project has no JAR to download, and how to get the source or the built file.

#Why didn't I get a JAR?
| Situation | Why | What to do |
|---|---|---|
| Datapack, Skript, Discord bot, website, Blockbench model | These types don't produce a JAR | Use Download (ZIP). See Downloads. |
| Java project, build failed | A JAR only exists when the build succeeds | See Compile failed. |
| Java project, "Build succeeded but no JAR found" | The build produced no output JAR (unusual build configuration) | Press Fix with AI, or ask the chat to make the build produce a JAR. |
| Java project, JAR rejected | The JAR had no compiled classes or no plugin.yml / fabric.mod.json / mods.toml | Codexe won't hand over a JAR your server can't load. Ask the chat to fix the descriptor. |
| Project still verifying | Compile is paused while Codexe checks the project | Wait for Ready, then Download JAR. |
#Download JAR is slow
If the current files haven't been built yet, Download JAR compiles first. That can take a minute (plugins) or several (mods).
#The source download is always available
Download gives you every file as a ZIP at any time, whatever the project's status, so you never lose access to your code.
