Fedora Eclipse will not start

[dmyersturnbull]

Hey.

Fedora Eclipse dies when I run it, giving this graphical message:

An error has occurred. See the log file
/home/dmyersturnbull/.eclipse/org.eclipse.platform_3.4.0_155965261/configuration/1238308055894.log.

And this console output:

I have been getting this error since I installed Fedora 10 using combination of Eclipse sub-packages. Running regular-breed Eclipse from www.eclipse.org works, but having package installation and updates handled by yum would be nice. Any ideas?

Thanks,
Douglas

Did you try
eclipse -clean
?

[dmyersturnbull]

Hey, pedromatiello.

Thanks for your reply.

>Did you try

Using -clean gives the same error.

[pedromatiello]

Well, try renaming your ~/.eclipse directory to something else and start Eclipse again.

[dmyersturnbull]

Hey again, pedromatiello.

I found the issue. Apparently alternatives was configured to use the Gnu Java Compiler instead—Fedora Eclipse was giving errors for that. I changed alternatives to use OpenJDK’s compiler and Fedora eclipse works now. I don’t know why using the gjc caused Fedora Eclipse to complain but not non‐Fedora Eclipse.

Thanks for your help!

Dear dmyersturnbull,

I am new to fedora and I do have the same problem.
I have no clue what you mean by "alternatives"
and how to configure them?

Could you please explain in more detail
how you fixed the problem, since my eclipse
doesn't start I don't now how to change its
configuration?

Thanks in advance.

If you want to know more about Fedora alternatives, take a look here:
http://dailypackage.fedorabook.com/i...es-System.html

If you want to change your Java machine, write in the console as root:
alternatives --config java
and choose the righ one.

To solve your problem with Eclipse, you must also rename your home/.eclipse directory, try to rename it to .eclipse.bk.
