Description

After the Java language server has started, attempting to save Java-files results in an error.

Steps to Reproduce

1. Open any Java file
2. Wait for languageserver to be running
3. Save file

Expected behavior:

I would expect the file to be saved.

Actual behavior:

In the UI, nothing happens.

In the developer console, this error is visible:

Uncaught (in promise) TypeError: Cannot read property 'Manual' of undefined
    at TextEditorSyncAdapter.willSave (document-sync-adapter.ts:331)

Reproduces how often:

Every time.

Additional Information

This was working last week, yet nothing on my atom install or OS has been updated since then. I have tried full reinstall, including reset of ~/.atom, to no effect.

I think this is the proper project for this issue, since this is the project that includes the vscode-languageserver-protocol package, but it might not be?

Bumping the vscode-languageclient dependencies in the atom-languageclient node_module and running npm install inside that dependency's folder has "solved" the issue. After that, I tried bumping the atom-languageclient dependency of this project to 0.9.9. This also solved the issue (by transitive dependencies), which means that is probably the correct solution.

I still wonder why this happened though...

I don’t know if you got it working, but let me give you some more detailed steps. This assumes you are on a Linux OS. 1. ‘cd ~/.atom/packages/ide-java’ 2. Open ‘packages.json’ 3. Under the ‘dependencies’ key, find the line which says ‘atom-language client’ and up the version to ‘0.9.9’ 4. Run ‘npm install’ Now the Java IDE should use the newer dependency, and saving files should work again. I hope this helps. Matthias Varberg Ingesman

Thanks @mdiin, I was running into this issue as well! I created a PR with the fix: #116

If anyone wants to apply this fix without needing to manually edit the package.json, follow these steps:

1. Find ide-java in the Packages section of Atom settings and uninstall it
2. Open Terminal and run apm install https://github.com/rajivshah3/ide-java
3. Restart Atom

Thanks @mdiin, I was running into this issue as well! I created a PR with the fix: #116

If anyone wants to apply this fix without needing to manually edit the package.json, follow these steps:

1. Find `ide-java` in the Packages section of Atom settings and uninstall it

2. Open Terminal and run `apm install https://github.com/rajivshah3/ide-java`

3. Restart Atom

So I tried your solution but when I run "apm install https://github.com/rajivshah3/ide-java"
It says
Cloning https://github.com/rajivshah3/ide-java.git failed Installing modules done Cannot read property 'getReferenceTarget' of null

and I don't quite get it why it doesn't work

Its probably cause @rajivshah3 uses a mac while Windows users might have to utilize a different way of getting around the issue, we need to add this directly to our path via System Variables though this PC system.

"%USERPROFILE%\AppData\Local\atom\bin" <---- That

[Tripp-Sautner]

It might already be in your path @grindarius so it might be just a java error within this package and maybe there are traces of a previous installation of the package causing issues

[rajivshah3]

 It seems like it’s already in the PATH however. The error they’re reporting is a JavaScript error.

I tried your method and still get the same error out of it. Maybe I need a fresh Windows installation?

This fixed my issue as well.

I met with this problem on macOS
atom --version
Atom : 1.45.0
Electron: 4.2.7
Chrome : 69.0.3497.128
Node : 10.11.0

And after the update node version to last 13.12.0 problem was solved.
So, in my case brew upgrade node resolved the problem

I can't save any files when java-ide is installed as an extension for atom. i tried updating the dependency to 0.9.9 without success. I have node.js 12.x installed as I have to run the LTS version. Is node LTS not supported for ide-java? Running on Windows 10
