Can you remove the java.home setting completely?
Is this a maven based project?

gorkem picture gorkem on 27 Feb 2017

I removed the user settings completely. Deleted all that was there and restarted but the same result.

mgcvnrpj picture mgcvnrpj on 27 Feb 2017

Downloading an ubuntu. I will try to replicate.

gorkem picture gorkem on 27 Feb 2017

It is a Maven project

mgcvnrpj picture mgcvnrpj on 27 Feb 2017

Is there any wrong settings I am doing from my side. I am attaching java configuration, user settings and the JAVA_HOME env variable. Please let me know if I am missing any settings

OS Details and JAVA Version below

OS Name: Microsoft Windows 7 Enterprise
OS Version: 6.1.7601 Service Pack 1 Build 7601
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) Client VM (build 25.121-b13, mixed mode)

Any update on the issue?

mgcvnrpj picture mgcvnrpj on 2 Mar 2017

I was not able to reproduce so far. I still need to find a win7.

gorkem picture gorkem on 2 Mar 2017

I also started experiencing this but on Windows 10 (also a Maven project)
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

I am experiencing this on Gentoo with JDK 1.8.0_121 and vscode 1.10.1; It seems the language server never completes startup. This is with a single small maven project. I see that the maven project also has a gradle option and I saw a backtrace related to the .gradle dir. The project is here: https://github.com/rubin55/microservices-demo

To reproduce, simply open the folder of that project, as the only folder open and see completion never work. Notice .gradle related backtrace when you click on the thumbs-up icon.

I suspect that some of the metadata that server uses gets corrupted and server shuts down itself, this may be rooted from #3. As @korn3l suggested deleting this metadata can be a workaround. Does it work for others?

gorkem picture gorkem on 7 Mar 2017

I can confirm that removing ~/.config/Code/User/workspaceStorage/ (I'm on linux) works! after removing that and starting code, completion works immediately.

I am still facing the same issue even after deleting %APPDATA%\Code
Tried it on vscode 1.10.1, Language Support for Java 0.0.11 on windows 7 for a maven project

@ffaubert thanks for the info.

gorkem picture gorkem on 9 Mar 2017

@ffaubert according to https://www.eclipse.org/forums/index.php/t/1078337/, this is benign (I checked the source and it's just a log). org.eclipse.ui.ide.multiFilter is added from a UI plugin, which jdt.ls is lacking. Did you open the same project in eclipse at some point, fiddling with UI filters?

@gorkem I wonder if it's worth providing a noop extension point for org.eclipse.ui.ide.multiFilter, to prevent that kind of errors

Anyways, that should be handled in a separate ticket.

yuchuangu85 picture yuchuangu85 on 8 Apr 2017

@yuchuangu85 The error that occurs is caused by a conflict between the .classpath definition and what Maven tried to set instead. I'm a bit confused as to why the server tries to import gdx-backend-gwt as a Maven project though, since it contains a gradle build file, it should be imported as a Gradle project. Which is what happens on my machine. Where (in the folder hierarchy) did you open that project from?

vscode: 1.23.0 and 1.23.1
vscode-java: 0.25.0
JDK: 1.8.0_162
Manjaro Linux 64-bit

Deleting workspaceStorage/ folder + restarting doesn't work.

It gets stuck in "37% Starting Java Language Server" forever. A process keep running and consuming RAM until there's nothing left.

When trying to "Open Java Language Server log file", nothing happens. In Developer Tools Console tab, nothing appears. Is there any file where I could get useful information to this thread?

one possible reason maybe gradle installation. after uninstalling all java-related plugins, problem solved.

Tried all internet hints:

  • disabled gradle setting (aka "java.import.gradle.enabled": false )
  • removed workspace (aka https://github.com/redhat-developer/vscode-java/wiki/Troubleshooting#clean-the-workspace-directory )
  • left only Language Support for Java plugin v 0.33.0 (remaining from MS recommended 'Java Extension Pack' disabled)

@matihost Do you use symbolic links?

snjeza picture snjeza on 1 Nov 2018

Yes, I have symbolic links.
After removing them (hints: find <workspace root dir> -type l for other people to locate them)
the problem vanished.
I would consider this as a bug.

matihost picture matihost on 1 Nov 2018

I think you had cyclic symbolic links.

snjeza picture snjeza on 1 Nov 2018

@snjeza ideally, LocalProjectScanner should guard against infinite recursion. @matihost can you describe how the links were set up, so we can reproduce the issue and guard against it?

fbricon picture fbricon on 1 Nov 2018

Re https://bugs.eclipse.org/bugs/show_bug.cgi?id=540700

snjeza picture snjeza on 2 Nov 2018

@fbricon
TL;DR
actually links comes from another RH product: https://github.com/openshift/openshift-ansible - present in the VS Code workspace.

The VS Code workspace root is https://github.com/matihost/learning
The java code is under algorithms or java subdirs,
but symbolic links are under: /openshift/okd-installation/okd-3.11/galaxy -
when make dependencies download them via Ansible galaxy requirement.yml file:

- src: https://github.com/openshift/openshift-ansible.git
  version: release-3.11

In other words - symbolic links does not have to be where Java code is located, but somewhere else in multilanguage workspace.

matihost picture matihost on 2 Nov 2018

I have a node_modules directory, which naturally comes with quite a few symlinks, and cannot delete it and have this issue. Might be related, dunno.

Okay, for me it had nothing to do with symlinks. I just needed to increase the heap by configuring vmargs. You can check for this from OUTPUT -> Language Support for Java

houmanMP picture houmanMP on 11 Mar 2019

@houmanMP node_modules is ignored during project discovery. Increasing the heap might be necessary for large projects (including many modules).

@matihost is this still an issue for you? The fix for circular symlinks has actually been applied weeks ago.

fbricon picture fbricon on 11 Mar 2019

Confirming that VSC: 1.32.1 + Java Extension Pack 0.6.0 + some ansible galaxy import with symlinks

  • the option ctrl + shift + P -> 'Java: Open Java Language Sever log files': should show also ~/.config/Code/User/workspaceStorage/..../redhat.java/jdt_ws/.metadata/.log shows
    zero exceptions.

Thanks for fix

@wtsiamruk could you try to set the following property:

"java.jdt.ls.vmargs": "-Dlog.level=ALL -noverify -Xmx2G -XX:+UseG1GC -XX:+UseStringDeduplication",

I can invite one people to see source of the project.. because on another simple maven project all runs ok, or even if i open child projects as separate folder, project runs, so i bet it is something in the pom itself, i use two annotation processors in that pom, lombok and mapstruct, could that be a cause?

I have been having issue of it never ending. Looked at the .log file and it was due to a git branch that had unmappable characters. I removed the branch locally and it now builds.

I remove workspaceStorage dir and uninstall plugin vsc-mybatis, it works!
