Eclipse won't start all of a sudden

[ilganeli]

After updating to the most recent version of Ubuntu I am having the same problems. Has anyone found a fix to this?

[achelis]

After changing to Eclipse Helios I haven't had problems with Eclipse on 10.4. I'm downloading from the eclipse download site - so not using apt-get. And I'm using the sun-java6 package.

This started happening to me.

I wonder if its because my java version may have changed?? :

java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Server VM (build 16.3-b01, mixed mode)

maybe some 32-bit vs 64-bit issue? (was the case for me)

[vivace]

hmm yea thats a possibility--i mean it makes sense since i think i may have installed some kind of 32 bit plugin. Do you know how i can fix it?? sorry im a complete noob.

I'm having the same problem. From what I gathered from other information gained from searching the 'net, the problem might be related to XULRunner updates. I do recall that my last update included XULRunner.

I don't have a solution, but perhaps this info might steer someone toward one.

I removed xulrunner as suggested here https://bugs.launchpad.net/ubuntu/+s...se/+bug/583552 and here http://www.dataforte.net/blog/2010/0...es-with-lucid/ but that did not work for me.

Luckily I still had the galileo install and starting that gave me an error message about an error in the log file /home/me/workspace/.metadata/.log.

I cleared the log file and then restarted Helios. Looking through the log file pointed to an empty file in /home/me/workspace/.metadata/.plugins/org.eclipse.core.resources/.root/

Root exception:
org.eclipse.core.internal.resources.ResourceException(/home/pradesh/workspace/.metadata/.plugins/org.eclipse.core.resources/.root/28.tree)[567]: java.io.EOFException
        at java.io.DataInputStream.readInt(DataInputStream.java:375)

Since the file was empty I deleted it and restarted it. Helios restarted it but with two slight problems:-
1. The window decoration looks "plain".
2. My project entries don't show up in the workbench.

My problem may not be the same as yours, but at least look in the
/home/me/workspace/.metadata/.log file for a clue.

Good luck

1. Disabled visual effects and try again.
2. Try installing manually
2.1 Download Eclipse IDE from the official web page.
2.2 Extract in /opt folder.
2.3 and run: ./eclipse.

I'm revisiting this issue after a long time. I had been using Netbeans during this time. I was surprised to find my own thread as the first result in google. Anyway, if anyone is still having this problem, the solution above worked for me.

I encountered the same problem after upgrading to 10.10 (and uninstalling/reinstalling Eclipse as that's usually required after a Ubuntu version upgrade to get it to play nicely with CDT), and unfortunately can find nothing that works for it. I've found Google threads that suggest using eclipse -clean, temporarily moving the ~/workbench and ~/.eclipse directories during the initial startup, doing a complete removal/reinstall, uninstalling/reinstalling xulrunner, and similar ones to those here such as removing certain entries in ~/workspace/.metadata.

None of those suggestions have worked, and I can't find any more. I also tried tweaking the config in .eclipse to use the main path (/usr/lib/eclipse) rather than just plugins/..., but no dice there either. Only a direct download from the Eclipse website worked, and that of course does not allow Synaptic/apt to control the upgrades. For the moment, it's what there is, though.

Has anyone had any luck in clearing this up? Everything above that I tried just results in the same error.

I have now got same problem (Ubu 10.4 64)
This thread has been marked solved, but what is the solution?
Or did i miss it?

Edit oh i see no that did not work for me either

I am going to have to go back to old ubuntu or use windoze < until this is resolved.
Unfortunately i cannot use netbeans (afaik anyway, it does not allow libs to be declared in android projects... or so it would seem)
