No java menu at preference option [message #1694664]

Hi everybody!

I have Eclipse 3.8 installed on kubuntu 14.04.2 from Muon Discovery. The complete story is I installed first, version 3.8. After that I tried to upgrade installing version 4 from website. Due an issue I found, I uninstalled it and back to 3.8 version.

The problem is now, on windows/preference menu there is no option called "java" at the left side of the window. Could you tell me why it is not showing that option?.

Thank you in advance.

Rethink this.

Eclipse isn't really "installed": You just explode the tarball to where
you want it. If you exploded the successive tarballs into the same
eclipse subdirectory the second "install" and/or again in the
"reinstall", you probably messed things up. Just pick the version you
want, download and "install" where you want it. Erase whatever's there
first.

As for the "java" at the left side of the window...dunno. The leftmost
pane by default in the Eclipse workbench is the Project or Package
Explorer View. I don't know of a "java" over there.

Depending on how they did their packaging, there may be additional packages you need to install. Also, 3.8 is a couple of versions behind. It might be worth getting the Java EPP download from download.eclipse.org instead.

Let me explain again the procedure I did:
1 - Installed from repository Eclipse 3.8. Everything was running well.
2 - I decided to try to install Eclipse 4 from website, then I uninstalled Eclipse 3.8.
3 - Eclipse 4 did not run fine, then I decided to uninstall it.
4 - I back to Eclipse 3.8 from repository. But I cannot see java option from preferences menu.

By the way, I am trying to upload a screen capture here, but I don't know why it is not working.

Thank you.

I'm guessing a package issue. Which 3.8 package did you download? It
should have been Eclipse IDE for Java Developers (or the one for Java EE
Developers).

Well, at repository is eclipse-platform 3.8.1-5.1. At first time there was no problem at all. Is was working very well.

Ah, you're getting it from some Linux repository.

That's a big no-no. Always download from eclipse.org--NEVER from your
package manager. This is ubiquitous advice you'll get from every
responder in this forum. The only time we don't advise this is for weird
platforms and I don't even remember a name of one of those. Ubuntu isn't
one of them.

Please download one of the packages I noted and you'll be happy.

Meanwhile, do this:

# apt-get purge eclipse-platform

OK, then. It is understood. We can close this thread with the advise: "Do not install Eclipse from repository, do it from website". Right?.
In that case I need to know how to install it in the correct way, because I am not sure I did right on last time. Is there any thread link or website where I can found those instructions?.

Thanks.

Here's the advice I always give. If Tomcat doesn't interest you, ignore
that bit.
