Hi All - I am looking to recruit multiple Java Developers to join first derivatives based in London at all levels. Ideally looking for someone with Financial Service background and knowledge of cloud technologies such as GCP/AWS/Azure

I'm having this problem,

Okay, cleaning out settings helped:
find . -iregex '^.*/[.]\(classpath\|project\|settings\)'  | xargs -t rm -vr
\rm -vr */bin/
and a bit annoying
I actually expected ./gradlew eclipse to do that

Hello All. working with a client who does their own desktop deployment package of VSCode. The base installation is locked down under Program Files. When I use the refactoring or apply a 'fix' I get the following error 'running the contributed command: 'java.apply.workspaceEdit' failed. Attaching log and version details as images. Note that because the client's build is locked down I run code with the --extensions-dir option so that I can install this plugin. Thanks in advance.

Hi, not sure if this is the right place to ask - but I'm trying to run a spring boot test in vscode which depends on pom.xml with the following:


And it fails on downloading it, probably since I'm running behind a proxy:

2021-03-16 23:09:08.309  INFO 2925741 --- [           main] o.s.b.a.mongo.embedded.EmbeddedMongo     : Download 3.2.2:Linux:B64 : starting...

My proxy is set up correctly in ~/.m2/settings.xml and I can run mvn clean install which downloads all the non-test dependencies automatically during build from the command line (zsh).

I tried setting the following according to https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-maven:

"maven.executable.options": "-Dhttp.proxyHost=my-proxy.org.com -Dhttp.proxyPort=911",

Any ideas?

Tomer Eliyahu
OK so I'm pretty sure that the problem is that the language server JVM doesn't set the proxy system properties - how can I verify if this is indeed the case?

I've set up my vs code for java. But while installing Language Support for Java(TM) by Red Hat extension it is giving an error. Here is the log message:

Hello, I begin my first project of code editing solo. Please how can I check that I have installed correctly VScode-java version for first time with all the required components ?
Prashanth Nandavanam
Hello all, the project I am the architect of uses Java (Spring Boot), NodeJS, and Python, among other technologies. My Java developers use Eclipse, IntelliJ, and VSCode. I enforce our formatting guidelines via an Eclipse formatter file, and that works well for Eclipse and IntelliJ. With VSCode, however, I am unable to get it to use the Eclipse formatter file. I have tried specifying the absolute location like this:
"java.format.settings.url": "/Users/pnandavanam/eclipse-codeformatter.xml", but VSCode simply does not use it. I've got the usual Java extensions installed, and not much else (The RedHat and Microsoft Java extensions). Any idea on how to get VSCode to use my Eclipse formatter? Thanks in advance!
@forwardmeasure could you create an issue at https://github.com/eclipse/eclipse.jdt.ls/issues/new/choose ?
In a monorepo with multiple java projects, why does the extension try to build all of them? How do I get it to stop?
Fred Bricon
@forwardmeasure you're facing redhat-developer/vscode-java#1827. Please try a CI build to check it's fixed in 0.77.0 for you

Hello everyone, I would like to create a VSCode Java Extension to enhance the existing VSCode Java features with a new kind of verification/diagnostic (related to refinement types in Java). I saw that this should possible (https://github.com/redhat-developer/vscode-java/wiki/Contribute-a-Java-Extension) and I was wondering if you could point me to a project that implements this kind of extension. Thanks in advance!
Catarina Gamboa
Thank you for the fast response @snjeza!
Anyone know how to prevent language server from truncating stacktraces when logging an exception? I'm hitting an issue with an annotation processor but most of the stacktrace is truncated ("... 25 more") and cannot see the root cause.
Nevermind, apparently org.eclipse.jdt.internal.compiler.problem.AbortCompilation is the root cause and doesn't provide any sort of message.
Good evening, does anyone knows if:

Does VSCode offer an intellij Keyboard mapping?

Hi everyone. Since version 0.80.0 the build status always stucks at 46% for our project without any more information or error messages. Is there a way to make this more verbose to see what's happening? Version 0.79.2 with the same project works perfectly fine

I am using prettier to format my Java code and have trouble getting the import order right. I want to use organizeImports on save to remove unused imports, but it seems that organizeImports runs after editor.formatOnSaveand messes up the order again. I have tried to replicate the order of prettier-java in my settings, but the way vscode-java sorts imports seems to be incompatible with prettier.
prettier-java will format

import lombok.experimental.UtilityClass;
import lombok.val;

and vscode-java ("java.completion.importOrder": [])

import lombok.val;
import lombok.experimental.UtilityClass;

This is just an example. It seems to affect all import statements that have a different package "depth".
Is there a setting to change the order in which formatOnSave and "java.saveActions.organizeImports": true run? I also tried

    "[java]": {
        "editor.codeActionsOnSave": {
            "source.organizeImports": true

this will switch the output between prettier-java and vscode-java everytime the file is saved. Alternatively, is there a way to configure the package order in vscode-java without listing all possible packages?

I have my java projects configured to use JavaSE-1.8 from build.gradle. That seems to be recognized in the status bar when editing a java file. However it seems that it allows me to use methods/classes that are from newer versions of java without complaining. My gradle build rejects it but in vscode it is just fine with me using List.of and autocompletes it even though it is not available in java 1.8.

@buzz-dee:matrix.org I'm using spring boot extension to resolve my beans. It's the only extension as far as I know that is able to do that. Unfortunately this extension doesn't resolve CDI annotation only spring support

hi, I'm trying to know if there is a limitation with maven support in vscode, as the language server doesn't resolve an additionnal source path added with swagger-codegen-maven-plugin.
This plugin generate javaClasses starting from swagger definition.

Sorry, but I'm totally green and don't get anything. I just start learning and figuring out how to set everything up and what resources to use to learn comfortably (to extend it is possible). I'm just looking for help in this regard.

Hi, I do have a project which uses my own annotation processor (https://lazysql.thomas-oster.de/). I got it working with using the maven-apt plugin as described here (https://github.com/redhat-developer/vscode-java/wiki/Annotation-Processing-support-for-Maven-projects). The problem is if the annotation processor throws a compiler message or warning, it is not displayed in the IDE.
how to run java frame program in vs code
I want to confirm some behavior before opening a github issue. No matter what I change, my multi-module gradle project in VSCode creates classpath entries and compiles code to bin instead of build whether the default or set explicitly. Is there anything I can check that would be misconfigured? This seems like a clear bug that I can't work around because the setting isn't able to be changed for the JLS when gradle is used.
https://docs.gradle.org/current/dsl/org.gradle.api.Project.html#org.gradle.api.Project:buildDir says the default is build. I have searched for the term build and bin in my source and I got nada. I tried setting buildDir in settings.gradle and nothing. I would be happy to provide my gradle properties, screenshots in vscode, and logs if you like.
back to intellij I guess
How can I tell what version of jdt.ls is being used by vscode-java? I appear to be getting hit by https://bugs.eclipse.org/bugs/show_bug.cgi?id=377850 which was fixed ~4.15
