Eclipse crashes after upgrade from Kubuntu 12 to Kubuntu 14.04

Question

I 'upgraded' from 12.04 to 14.04 and I'm having a problem .I can't seem to fix with eclipse. Specifically, eclipse crashes... consistently. I've looked over the web for a few days and I can't seem to fix this problem.

I have removed eclipse with autoremove and remove and done a clean and autoclean but that doesn't seem to blow-eclipse away totally and I think that is what I need to do to get it going again... remove and delete all the configuration files... something is incompatible or in the wrong format for the eclipse version that I have now and what I was using under 12.04?

Here's the start of the sad story:

I knew eclipse was going to be a problem when I started it and it complained about the workspace being in-used or not existing... (it did exist and was not in use... and I could find no lock file) After that I kept 'browsing' over to the workplace and eclipse would crash.

So, I did an sudo apt-get install eclipse... and apt-get said it was selecting previously unselected package and acted like it was re-installing eclipse without downloading anything. After that eclipse would start and when I pointed it to my workspace folder, it went to it and opened the projects that I had previously been work on.... but I noticed all the '.c' files had the icon for Geany... HRM... looks like no CDT... so I went to help->install new software.. and ->All Available sites... nothing listed. Also, none of my plugins are listed as available, no SVN, no CDT, no XML modeling, nothing. So, I tried to update the proxy information and it crashes every time. It will also crash if I go into the general section and try to change anything. But to make it easy the following steps will crash every time for me.

Here's how I can reproduce it:

1. start eclipse
2. window->preferences
3. expand General and select Network Connections
4. Select the HTTP under 'Proxy entries' and then edit.
5. Change it, or don't and press 'ok' in that dialog box BOOM, dead

Here's what goes into the terminal window after the window disappears from KDE:

I have the crashlog file, and it is quite long, if it'll help I can post it or excerpts from it if needed.

update: It seems anything that changes the workspace or the settings for Eclipse will cause Eclipse to crash. New project... crash. Also, even though I did an apt-get install eclipse-cdt, Eclipse doesn't seem to understand what a .h or .c file is. Nor can I choose a c project from the new project wizard.

Don't bother with eclipse version that apt-get provides you

Go straight for the official version on the official site. Follow the steps from this this answer.

The advantage installing with apt-get:

• one single sudo apt-get install eclipse command to install eclipse

The advantage installing your own:

• You can choose what version of eclipse you want. Be it the latest greatest or something older.
• You get to choose when you want to update. Updating in the middle of a urgent project isn't fun.
• Sometimes newer eclipse need more RAM, CPU, HDD space.
• Eclipse is keeping itself up-to-date if you want. It is also keeping tab of the installed plugins as well. So you don't need apt-get to keep that one updated too.
• Eclipse will tell's you when there is a new version of itself and gives you a choice to update it now or later.

I've been working about 4 years with Java on eclipse (also Intellij IDEA) on Linux on day job. Using the official version was never a option as there were always plugins I needed to use that only worked with that special version.

Installing eclipse manually might seem cumbersome the first time. But once you've done it it's very easy the next time.

If you are using Eclipse Luna, this will crash when attempting to create a new java project or another type of work.

To solve this (worked in my case), do the following:

1. Go to System Settings
2. Go to Application Appearance and open the GTK tab
3. On GTK Themes, in GTK2 Theme, select another different to oxigen-gtk, like Clearlooks
4. Apply
5. Exit and make sure Eclipse is closed
6. Logout an login again to make some visual changes to take effect
7. After login, open Eclipse and test.

I'm using Eclipse Luna 4.4.1, Clearlooks as GTK Theme, on Kubuntu 14.04.1 x64 and java version "1.7.0_72".

I hope this help :-)

Answer 3

This is caused by a known bug that appears when upgrading from 3.7 to 3.8 of eclipse (which a distribution upgrade from 12.04 to 14.04 effectively does) Also current versions of eclipse (4.4+) will have similar issues, check this bug report:

https://bugs.kde.org/show_bug.cgi?id=339174

The work-around is essentially to install the gtk engines and then go into system settings for x windows and de-select the gtk engines... and then relaunch eclipse.

Even though this bug is against 4.4, the same fix worked for me with 3.8.

Thanks for the help!

P.S. Mike, just going off grid with the eclipse version does not fix this, nor is this a variant of 'installing eclipse'. I do not appreciate your spamming this question with unsuitable and plain wrong answers for 'rep-points'.
