Hi I am wondering if anyone found some similar issues upgrading from ubuntu machine.
I upgraded from eclipse mars to eclipse photon and when I try to run my Tomcat 8 server I get the following error.
Plug-in "org.eclipse.jst.server.tomcat.core" was unable to instantiate class "org.eclipse.jst.server.tomcat.core.internal.TomcatLaunchConfigurationDelegate". org.eclipse.jst.server.tomcat.core.internal.TomcatLaunchConfigurationDelegate.allowAdvancedSourcel
I have tried updating all repo's to no success, I read some threads about WTP ServerTools so I tried upgrading to version 3.10 and this will not update for me either, any ideas would be grateful.
Or should I just do a reinstall to the version I had working, would properly save time in the long run
I'm having the same issue. I upgraded from within eclipse (Oxygen) by entering the new repository location.
Java 8 / Ubuntu 18.04
I then couldn't start tomcat with the above noted error.
I just ran apt update & apt dist-upgrade but it didn't pull down any relevant packages.
I then ran the 'Help | Check for Updates' option in eclipse and it installed some wtp tool updates. I then deleted the Server instance in eclipse and re-created it.
Tomcat now starts correctly.
Summary:
Run 'Help | Check for Updates' in eclipse and it looks like that will fix your problem.

I was trying to install WildFly/JBoss Server in Eclipse IDE Photon Release Candidate 3 (4.8.0RC3) but I'm getting an error. I have attached the screenshot for the same.
Would somebody help me out here in this issue?
I've had the same problem.
In Eclipse -> Help -> Eclipse Marketplace, search for "TM Terminal". Uninstall it, restart Eclipse and try to define a new server again. It will now install Wildfly, at least for me it worked.
I've had the same problem. I was using Eclipse 2021-06 version and whatever I do I couldn't get the JBoss Community folder with different Wildfly servers to show.
I've downloaded the newest Eclipse (it was 2022-09 at this time) and everything was there after I installed the JBoss Tools in Eclipse Marketplace.
I installed a fresh Ubuntu 16.04 VM, Oracle JDK 7, and downloaded the latest Eclipse. But I am getting this error when I try to start Eclipse:
Unrecognized VM option 'UseStringDeduplication'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
Why am I getting this error on a fresh install? And is it a bad idea to remove that VM option?
Latest version of Eclipse (Neon) requires Java 8 runtime, and the Eclipse website obnoxiously neglects to mention it anywhere from the homepage to the download link for Eclipse, not even a version warning at runtime for Eclipse.
Same error for me in Kubuntu 14.04, eclipse Neon,
I Removed -XX:+UseStringDeduplication from .ini file, it works for me
I know, i'm little to late to the party. I got this issue lately on my Mac. I updated my eclipse (from Mars to Oxygen) all of the sudden i couldn't start my old project. First i thought, this must have something to do with the new eclipse, which wasn't all wrong. Because eclipse.ini file of Oxygen expected java-1.8.
I updated my java to latest (jdk1.8.0_152.jdk), but the problem remained, than i removed these parameters from the eclipse.ini, still was the same, i checked the "Run Configurations" and basically removed the same parameters from the arguments list. Now my projects seem to work just fine. I also needed to restore the platform, since Oxygen use e.4-platform.
Remove these parameters from eclipse.ini file
Select the project and go to "Run As"->"Run Configurations..."-> "Arguments" check the old configurations under "VM arguments" (it can be a product in case of an RCP-project)
removed the VM-option(s)(actually, they can be more) not recognized and "Apply"-> "Run".
I got the same error when I have installed Java 8 and Java 9 in my Ubuntu 16.04. My eclipse version was Neon. As https://wiki.eclipse.org/Eclipse/Installation#Eclipse_4.6_.28Neon.29 describes to start specific eclipse ide you need relevant JDK. For neon, it was Java 8. Since I installed Java 9 using apt-get it was the default JDK. so I have to change the default JDK to Java 8.
You can check which java version used in system-wide with
java -version
`If you want to see which are the versions of JDK installed in Ubuntu then run below command in shell.
sudo update-java-alternatives --list
Then choose which version you want to set. After that run below command.
sudo update-java-alternatives --set [JDK/JRE name e.g. java-8-oracle]
Now run again Eclipse. if the version was the reason to conflict, it will run now. Referred by http://menukanows.com/how-to-set-a-default-jdk-version-in-ubuntu/
String Deduplication – A new feature in Java 8 Update 20
It means you should nt java 1.8 updated later or equal 20.
I faced the same issue on Eclipse Oxygen in Ubuntu.
Tried:
Checking java version (It was already at 1.8.0 so according to the accepted answer, it should work.)
Removing -XX:+UseStringDeduplication from .ini file
Still didn't solve the problem. Then I saw #simgineer's comment:
In my case this was for eclipse oxygen. I had an older version of java
8 installed (jdk1.8.0_05) when I upgraded to the latest (jdk1.8.0_151)
and updated my eclipse.ini to point to the latest as well (since it is
recorded in there during installation) eclipse oxygen started working.
Solution:
Updated JDK from 1.8.0 to jdk1.8.0_231 and it got resolved.
Voila! I didn't have to update anything in my eclipse.ini .
I recently updated my ports on my FreeBSD 9.0 release machine and I think eclipse was upgraded due to a port upstream forced Eclipse to be rebuilt. Now Pydev is gone. I tried uninstalling then reinstalling Eclipse, then installing Pydev using pydev.org/updates inside Eclipse. It appears to install ok but I can't create a Pydev project or use the Pydev view. I tried removing my ~/.eclipse folder to force the creation of a new one, and reinstalling Eclipse and Pydev to no avail. What am I doing wrong? I'm running Eclipse Indigo version 3.7.1 build id: R3_7_1
This question was most similar to mine, but the solution didn't work for me. I also tried pointing my install site as: http://update-production-pydev.s3.amazonaws.com/pydev/updates/site.xml per another question on StackOverflow, to no avail.
After some more testing I finally got the newest FreeBSD port to work. I had to launch and install the plugins as root. It didn't work another time I ran it but, this great troubleshooting document helped out. I methodically went through each step one by one, and the logs indicated there was an error on my /usr/local/lib file it was trying to unzip. My user doesn't have write access to that directory but root does. I don't know why it didn't work the last time I ran it as root, perhaps I didn't install the plug-in as root. It works now, so I'm happy. Thanks Fabio, for your input.
I'm not sure how FreeBSD packages things, so, maybe an easy way out would be getting Eclipse from Eclipse.org and installing PyDev on that fresh install (or if you're also doing web stuff, I'd suggest grabbing Aptana Studio 3, which comes with PyDev preinstalled, so, you don't have to worry about configuring it).
See: http://pydev.org/download.html for details
I just upgraded my version of Eclipse on Ubuntu, and now whenever I open a Python file it opens in an external window, and the existing Python files I have open in Eclipse say "Could not open the editor: No editor descriptor for id org.python.pydev.editor.PythonEditor".
I tried uninstalling and reinstalling both Eclipse and the PyDev plugin, and it didn't fix the problem.
From my experience (~8 years) with eclipse don't do in place updates. Always install a fresh version with a new workspace. And re-checkout projects from SCM.
Check first whether all required plugins still work before switching to the new environment.
Make sure your Java version is correct (what your version of PyDev is expecting).
After I updated PyDev (5 min ago) I had the exact same error message displayed in the tabs where I once had python source files opened (No editor descriptor for id).
I updated my Java version from 1.7 to 1.8 with:
sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
Then to check your version, run:
java -version
You should see something like:
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) Server VM (build 25.91-b14, mixed mode)
Re-opened eclipse, and the PyDev plugin is working. Yay!
Actually, when you install Eclipse new version then new plugins are installed which lead to change in ubuntu libraries and installing again will not take effect until you install new plugin which is supported
I had same issue, when I updgradet PyDev with newest version 3.*. It needs java 1.7, but I have only java 1.6, so it does not work at all. I uninstalled it and set eclipse to old updating point, but nothing helped. Advise is to use PyDev versio 2.82. You can not find it from update repositories.
Only way is to download old version 2.8.2 from PyDev site, unzip that zip file to eclipse's drop in directory, in linux it is /usr/lib/eclipse/dropins. After unzipping you should see there features- and plugins-directories. And after some starting of eclipse, I could see PyDev again. At first restart of eclipse I could not see PyDev and tried "Check updates" and "Install new software" settind url to /usr/lib/eclipse/dropins but they did not see any software there. But trying to restart few times, old PyDevc 2.8.2 was in eclipse again. Huh.
I disabled PyDev from eclipses "check uopdates" so I don't make that error again, this machine will not get java 1.7 (Ubuntu 10.04 LTS).
I now ran into exactly the same problem when updating to PyDev 5.0 and its definitely an issue that the user is not warned that the program might break on update. However, the simplest solution is to install the new required Java and JRE version, for PyDev 5.0 that's Java 8 and OpenJDK 1.8 (on Linux), and tell Eclipse to actually use the new JRE in the eclipse.ini file, by pointing it to the right path. See https://wiki.eclipse.org/Eclipse.ini#Specifying_the_JVM on how to achieve this.
I have a major problem with installing plugins in eclipse. I'm using ubuntu 10.04 64 bit and I installed:
Eclipse SDK
Version: 3.6.0
Build id: I20100608-0911
(Not by using the apt-get, via apt-get I get galileo, but that version didn't work as well)
The Plugin I want to install is: http://sourceforge.net/projects/jbpm/files/jBPM%203/jbpm-jpdl-3.2.7/ I have to use this plugin because its compatible with alresco (dms)
I tried to install the plugin via dropin and the normal way:
Help->Install new Software-> Add -> Archive -> select the downloaded *.jar.
When I hit OK, I get the following error message:
"Could not find jar:file:/home/xyxyx/jbpm.jar"
I tried to solve it by extracting the jar but no success. Putting the jar into the plugins folder and changing permissions won't help! I also tried different versions of eclipse on several systems. No success!
I have been looking for a solution all day! I tried some advice I found on stackoverflow. I don't use a proxy. I changed the update system to classic! Now I don't know what to do anymore.
Anything special I have to configure before I use eclipse on ubuntu besides installing the JDK?
Try to run the installed using the following command:
java -jar jbpm-installer-3.2.7.jar
On the other hand, you may want to use JBoss IDE which has integrated support for jBPM.
