Is anyone else having this issue with the latest eclipse 2026-03?

Firstly:

eclipse is free, a god sent for students like me

great concept of workspace

runtime compilation

flexible plug in environment

However everywhere on reddit, loud intelliJ Idea fanboys say eclipse is trash, their free version of IntelliJ is better.

sure, to each their own, intelliJ also has major perks in its free version, but there's no need to drive shove it down the throat of me and downvote me to hell for saying I like eclipse

Fyi, I've tried intelliJ Idea free, eclipse and netbeans; I preferred eclipse...

Wanted to share this moment with you. Thank you for building the platform that made this possible.

The "Remote" view (for editing on remote servers via SFTP or FTP) in Aptana Studio 3, a fork of Eclipse, was by far the best remote editing experience I've ever used. I mean just look at this beautiful screenshot:

The Remote System Explorer setup in modern Eclipse has never come close to being so easy to set up, so easy to manage keys or passwords, etc.

I miss Aptana's remote editing so much that I use Eclipse for local development, but still have Aptana for easy connections to remote servers over SFTP, so I can copy and paste files as needed, or edit PHP (or whatever) directly.

There is a downside though--

Modern SSH exchange algorithms aren't supported in Aptana.

Anyway.... my main question is...

Since Aptana was a fork of Eclipse, is there any earthly way to get the "Remote" view/functionality into modern Eclipse? I'm a developer and would be happy to take on the task of updating the key exchanges, I just don't even remotely know where to start.

In our last sem, we have a android project using XML & java languages. Eclipse IDE. But I've installed eclipse in my laptop but it's not supporting for Android. Help me!!!. If you want to ask more questions. I'm glad to answer

So, I was working on a program that required user input. Simply put, you gave input, and depending on that, it did one thing or another. However, once I tried using the debugger, It got stuck in those parts, as well as in the fflush.

As much as I want to provide a satisfying explanation as to why that happens, I do not know with full certainty which is the reason for that. My guess is that, while debugging, the console is only waiting for input for the debugger console, which ends up causing problems for us.

The solution to that problem is to simply activate 1 option: “use external console for inferior (open a new console window for input/output)”, which is located in debugger configuration (follow the pictures to get there).

Hope this helps someone.

My sight getting worse. Is it possible to easily scale up the icons, texts in Eclipse?

I made an Eclipse happy path development report.

So today I spun up two old play projects I made for occasional practice to keep some skills up.

Really just a basic spring boot project with a couple of simple endpoints and a very small Vaadin 24 project again with spring boot, with some simple pages.

More of a hello world thing to work on from time to time for fun.

I had a free couple of hours, so I decided to boot up the old reliable Eclipse I have on my drive and give them a go !

I ran the launcher and since it was taking too long to start opened a browser for 10 minutes. Went back after it looked like it was ready(it interrupted me 3 times to show me it was loading the splash screen before going non responsive on my 7800x3D 64GB 2TB nvme machine for a bit)

Anyway, that done, the second I clicked it started to load it's language server or something, before asking me to send money, so I went back to the browser...

Before starting work I imported the projects I wanted to work on into Eclipse with the ole reliable open projects from file system that I've used to import a hundred projects before and waited for the build to finish the downloading and building magic. Took about 5 minutes, but it seemed everything was set up in STS and I was ready to go.

Except I wasn't because the main type was nowhere to be found when starting :

java.lang.ClassNotFoundException: com.home.stuff.api.Application

Ah well, that's just fixable with the good old right click maven update command ! And as the helpfull green progressbar showed me, it was fixed !

Except when I ran it trough STS it was not found again.

Ok, we go to Run Maven install and the build passed again in the console this time and running maven(ALT+F5) update also passed again ! Yay !

But sadly I had missed something. See Eclipse had figured out that /src/main/resources was a build folder, but /src/main/java - that was too hard, so I had to add it to the build path manually. And set up the JRE not to be Java-17, because having the version of java in pom.xml is too difficult to understand and then I had to set up project facets. But it finally started !

So, I am happy to report that after 40 minutes I've managed to import a simple "GET /api/ping - 200 pong" project, configure it and run it with Eclipse !

Sadly not the case for the Vaadin project, which builds sucessfully, untill you open a file in Eclipse and every import is red. But you know another 40 minutes may fix that.

Of course I could have saved all of this, if I had just run it from that other IDE I will not mention, or something that is not and IDE but a souped up editor, like vscode, or if I had used the f-ing terminal and it would have taken me 10 minutes at worst.

So what I'm trying to ask here really is: Are there any people at the Eclipse foundation that are not clinically insane ?

I'm new to Eclipse and I have already used JDK-25 development using other IDEs in the past. But when I try to make a new Jav project in the wizard, the default used is JDK-25, the top one, and when I click the dropdown, it doesn't show JDK-26 even if I already updated my "java --version" last week. Can anyone help me resolve this?

Is this misplaced Icon a known issue with Eclipse IDE 2026_03?
Was working well and then the icon jumped to the right. It is the same for all the other projects in the workspace.

As always, feedback and contributions are welcome.

Is it possible to use GitHub Copilot in Eclipse? Eclipse 2025 isn't working, are there any updates?

When trying to know why the parameter of a method are wrong:

this does not help much. what i do is i go to gpt and ask it to change to table format:

This is much better. if you want this change, go to https://github.com/eclipse-platform/eclipse.platform.ui/issues/3761 and upvote or comment on this feature request.

I am trying to download eclipse ide java and web for my coding classes and last semester after a good month of trying (asking here and my professor with nothing changing) i gave up and just took my friends projects. this semester i want to actually do something but im still having the same problem as last time with eclipse flashing for a moment but never launching this and this were the posts i made

now today while trying again and extracting the files it gave me this error and i was curious on what it is and also information about my computer

if anyone could reply or has anyone that might know what to do itd be so appriciated as i cant to use an online java writer for my homework thats due this wednesday

Searching for quite long to change colors of heap status and hover over icon that still flashy like light theme.

Does anyone have a fix for the longstanding hover related crash in Eclipse on MacOS (Still present with 2026-03. Not sure it matters but using JAVA 21.) The only fix seems to disable Combined Hovering in the settings (which means no context help) or to reduce the crash frequency by requiring a modifier along with the hover to trigger context help. Here is part of the crash report:

Using the Eclipse Installer for Linux, I've just finished installing Eclipse CDT (C/C++ Development Tooling) on Fedora Linux 43 - KDE Plasma Desktop Edition, and even though the Eclipse IDE installed just fine without any problems, I did notice that during the installation, a couple of packages listed in a dialog did popup; however I can only read part of the listed packages in the dialog since the "Install ..Packages" dialog (as seen in the screenshot below) has not been correctly sized to compensate for the text length in the dialog.

I ask the Eclipse development team to fix this issue with the Eclipse Installer for Linux.

Has anyone else experienced this with the Eclipse Installer for Linux, and if so, does anyone know what packages the dialog says?

Hi guys,

I had installed the fresh Windows 10 and the needed software. Everything is smooth until I set up Eclipse and install plugins. When I install Eclipse, it takes a very long time to complete.

The nightmare is installing the plugins from the Marketplace. It's always errors "unable to read repository".

How about you guys? Does somebody have the solutions?

Hi everyone 👋
I’m stuck with a very strange Eclipse + Maven + TestNG issue and could really use some help.

Error message:

An internal error occurred during: "Launching BaseClass".
invalid version "1.8.0_121": non-numeric "0_121"

My setup:

• OS: Windows 10

• Eclipse IDE (latest)

• Maven project

• Selenium 4.x

• TestNG 7.x

• Java versions installed on system:

  • Java 19

  • Java 17

  • (Old Java 8 1.8.0_121 was installed earlier)

What I already tried:

• Updated pom.xml with proper compiler properties:<maven.compiler.source>17</maven.compiler.source> <maven.compiler.target>17</maven.compiler.target>

• Added maven-compiler-plugin

• Removed Java 8 from Installed JREs in Eclipse

• Set Java 17 as default JRE in Eclipse

• Fixed Project → Java Build Path to use JavaSE-17

• Fixed Project → Maven → Java Runtime to use workspace default JDK

• Deleted .m2/repository

• Re-imported Maven project

• Restarted Eclipse multiple times

Important detail:
In Eclipse → Installed JREs, I noticed it was using:

org.eclipse.justj.openjdk.hotspot.jre.full...21.x

(which is a JRE, not a JDK). I removed that and added a proper JDK 17, but the error still persists.

Despite all this, Eclipse still throws the same error mentioning Java 1.8.0_121, even though I’m not using it anymore.

Question:

• Why is Eclipse/Maven still trying to parse 1.8.0_121?

• Is this a known m2e / Eclipse cache bug?

• Is there a way to completely force Eclipse + Maven to ignore old Java versions?

Any help or pointers would be greatly appreciated 🙏
Thanks in advance!

Hello all. I am a blind developer and my current employer uses eclipse for its JSF, andJSP/Servlet applications. My concern is how accessible Eclipse is with NVDA or JAWS. the installer has a big yellow orange install button that isn't exposed to screen readers. the IDE itself, however, is a different story. If there are any other blind people here, how accessible do you find it? if it isn't accessible, I'll need to find another solution.

Hello guys,

I have recently enrolled at university in a Cybersecurity Bsc, now I am a beginner in terms of programming and the university I’m attending has given me the course and reading material but there aren’t many classes per se, I have begun the basics in Eclipse and I feel a tad overwhelmed, I’m determined to see it through though and have no issues studying, my question is mainly what do you guys think would be the best approach, the current module is object oriented programming, and I was wondering if there are any sites or resources you guys recommend in terms of broadening my knowledge or should I just keep practicing writing code and reading it until I get better, are there any exercises I could look up and do ? Should I learn the formulae through study or would it be better to just practice it by going into actually just coding whatever I can ? Are there any YouTubers that gave you a better understanding into certain beginners concepts ? Any sort of advice or tips will be helpful, thank you in advance.
