Eclipse fails to start (java.lang.ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter)

[Vidar]

I just installed 18.04 from today's March 10th desktop ISO in a VM with all default settings. I proceeded to install Eclipse and build tools with:

    sudo apt-get install eclipse git build-essential

I then ran `eclipse` in a terminal from my home directory (launcher icon behaves same way). I expected Eclipse to open, but instead I got a popup saying:

    An error has occurred. See the log file
    /home/vidar/.eclipse/org.eclipse.platform_3.8_155965261/configuration/1520710304064.log

Meanwhile, the following messages are printed on stderr:

    OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
    Gtk-Message: 11:31:25.572: Failed to load module "canberra-gtk-module"
    Gtk-Message: 11:31:25.619: Failed to load module "canberra-gtk-module"

The file it mentions contains:

`eclipse`, `eclipse-jdt` and `eclipse-platform` are all version 3.8.1-11. There are no pending updates after an `apt-get update && apt-get upgrade`. Installing libcanberra-gtk-module got rid of those warnings, but the popup and error message remain.

[Hans Joachim Desserud (hjd)]

Thanks for taking your time to report this issue and help making Ubuntu better.

I can confirm this issue, eclipse 3.8.1-11 fails to start when I attempt to run it on Ubuntu bionic. Based on the error message, I found a corresponding bug report in Debian, so I have attached a bug watch.

Btw, when reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. This adds version numbers and additional information automatically, making it easier to process bug reports. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

[vital (vsbogd)]

Have the same problem.
Seems root cause is a broken dependcy:

eclipse-platform version is 3.8.1-11 it depends on eclipse-rcp version 3.8.1-11 which in turn depends on libequinox-osgi-java (>= 3.9.1).

But eclipse-platform-data expects libequinox-osgi-java version 3.8.1-11:

$ apt-cache --recurse depends eclipse-platform | less
eclipse-platform
  Depends: eclipse-rcp
eclipse-rcp

Is there a workaround for this ?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Hans Joachim Desserud (hjd)]

Based on duplicate bug 1777421 it seems the underlying cause might be that the package org.eclipse.core.runtime.adaptor is not installed into /usr/share/eclipse/plugins/.

[gimfoxhound (gfoxhound)]

Let's summarize the situation!
Yesterday I was happy to pass from Kubuntu 14.04 -where everything were fine- to Kubuntu 18.04. Today I tried to simply access to another windows desktop. Impossible! Because of 'too much security'! I set up MySQL workbench with MySQL server, with the Workbench client I tried to access to mysql server -port 3306- impossible yet!
I tried to set up Amule, just for the fun, KAD is blocked!
I tried to set up and launch Netbeans, bad idea! It did not work! Netbeans failed to launch. After I set up Eclipse, and I tried to launch Eclipse I retrieved this kind of beautiful message 'An Error has occured....! etc...' the same message shown above. I foresaw to install Weblogic and Websphere, but ...it seems to be a bad idea, regarding my "Hot" experience since yesterday! What the hell did U do ? Is Kubuntu 18.04 be an O/S ?
Why didn't you warn us that Kubuntu 18.04 is only made for connecting funny smartphones, and tablets with Desktops ? But mostly not for other things!

I left the world of Microsoft since 2006. I don't want to be back! Since 2008 I only know the world of Ubuntu/Kubuntu. Yes indeed, in the past there were some bugs. It is normal! But at this scale I could never imagine! It seems to be and indictment!
What should I do now ?

Also affecting me. Are there any updates on when a fix for this might be released?

[C. Jeffery Small (loyhz2ay-jeff-h670zbts)]

I don't understand how things as critical as this are not being fixed immediately? Netbeans also fails to start. This is a java problem in both cases.

[Jef (e70838)]

Sorry to be another metoo, but the purpose of 18.04.1 LTS is to ensure this does not happen. The problem has been found in march, we are in august.
I use my computer for java development using eclipse. This issue is not even mentioned on https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes.

I understand that bugs hapen and may be hard to fix, but I can not understand the communication around this issue. Maybe it is a bit myopic, but why did 18.04.1 went out before fixing (or at least having a work around for) this issue.

[Jef (e70838)]

Silly me! There is a simple work around:
​apt-get purge eclipse ; ​apt autoremove
Download Eclipse Installer on https://eclipse.org/downloads and install it as non root.
My apologizes.

[Cruncher (ubuntu-wkresse)]

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891956#47 for the reasons behind why this is not being fixed

[Makis Livadas (glivadas)]

On Raspberry-Pi and Ubuntu 18.04 LTS no simple work around for me here. Only work around on Pi is to use the Rasbian interface. So this should be a critical bug for 18.04 LTS.

[Michael Gorriz (mgorriz)]

I guess you guys need explicitly Eclipse 3.8 . Just go to Ubuntu-Software, deinstall 3.8 and install Eclipse 4.8 (Photon) which is the default package on the Ubuntu-Software.

[Kevin Matthews (kevinwmatthews)]

Hi Michael,

Where do you see that Eclipse 4.8 is the default on Ubuntu-Software?

As far as I can tell, Eclipse 3.8.1 is the default for Ubuntu Bionic (18.04 LTS).
See here: https://packages.ubuntu.com/bionic/eclipse

I didn't notice an entry for Eclipse in bionic-updates, either:
https://packages.ubuntu.com/bionic-updates/allpackages

I have had success installing Eclipse manually, but I think the issue is that the package manager installs software that doesn't run.

Thanks for your help.

[Thomas Maeder (maeder+launchpad)]

eclipse still doesn't start on Ubuntu 18.04 all patches applied.

Is this going to be fixed at all?

[Jim (dgtlrift)]

Another month and still no fix... when will this be fixed?

The workarround purposed by Jef (e70838) at answer #11 works for me.

@jasepow

Seeing your log, I noticed your java version was 11.0.3

You need to use java 8:

$ java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

I suggest you to either uninstall your java 11 or use "sudo update-alternatives --config java" to switch your default java to version 8:

- https://computingforgeeks.com/how-to-set-default-java-version-on-ubuntu-debian/
- https://tecadmin.net/switch-between-java-versions-on-ubuntu/
- https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-on-ubuntu-18-04

Afterwards, don't forget to rerun the workaround steps:

$ sudo wget http://archive.ubuntu.com/ubuntu/pool/universe/e/eclipse/libequinox-osgi-java_3.8.1-8_all.deb

$ sudo dpkg -x ./libequinox-osgi-java_3.8.1-8_all.deb /
$ sudo apt install --reinstall libequinox-osgi-java
$ eclipse #(this should launch)

@pinubigfoot #30

Same situation here : Java 11.0.3.

I installed Eclipse and the JRE came with the dependencies : 'eclipse' depends on 'eclipse-jdt' and 'eclipse-pde', both depending on 'default-jre | java5-runtime | java6-runtime' (sic !), and 'default-jre' in turn depends on 'openjdk-11-jre'. Same goes with 'eclipse-platform' etc.

If current Eclipse packages effectively depends on a Java 8 JRE, why is it that the dependencies chain is not installing 'openjdk-8-jre' and automatically configure Eclipse to the use of this JRE ? Why all these incorrect dependencies ?

All the Debian and derivative distros package systems rely on correct version dependency management by package maintainers, relieving the user of any tedious error-prone task of manually managing the packet versions dependencies and environment configuration. 'sudo apt install eclipse' should result in Eclipse being immediately executable, as any other software installed with this command. I chose Ubuntu, a Debian-derived distro, because i didn't want to loose time manually fiddling with package installation and configuration.

So, please, the Eclipse packages do need to be corrected according to Debian-based package policy and should not depend on their users painfully manually tidying the mess.

Follow the steps on my update #30

You should be able to launch it once you have downgraded your jdk to version 8.

Make sure when you run "java -version" from terminal, you can see version string "1.8.0_XXX"

Helo¡¡¡
The answer #30 worked for me.
Ubuntu Linux XXX 4.15.0-66-generic # 75-Ubuntu SMP Tue Oct 1 05:22:52 UTC 2019 i686 i686 i686 GNU / Linux

Hello,

The workaround may work but dependencies are still wrong in the Eclipse DEB packages, since they demand the different versions of Java but not the right one, as already described in comment #31. If Java 8 is required, then the dependencies should relate only to Java 8. They should not absurdly demand Java 11 ('default-jre') or Java 5 or Java 6 any more!

The package needs a correction, not a workaround by end users.

Nothing has been amended for months at all (see 'apt show eclipse-jdt' or 'apt show eclipse-pde' for example). The Eclipse package dependencies are still a mess.

Is there a way to have the package maintainer eventually correct those unacceptably crappy package dependencies?

Arnaud

I just tried to apt-install eclipse on my Linux Mint 19.1 machine, and ran into this problem. The workaround in comment #30 did the trick, but I have to say I agree with @lucasarnaud79: this situation is unacceptable. Managing dependencies is the package maintainer's job, not the user's. The latest update on this thread says "Fix Released", but the problem still seems to be occurring.

I'm sorry, I made a mistake.
This status is incorrect.
