Has anyone installed Eclipse 2020?
Which Linux distribution are you using?

~~~~vmelkon

On Fedora 33 with GNOME.

I had it installed via the Software app. Uninstalled it and installed via the Eclipse installer. Just because.
Both seem to work.

Did you download the installer from eclipse.org?
Is this the file name or am I downloading the wrong thing?
eclipse-inst-jre-linux64.tar.gz

I decompressed it and double clicked on executable file = eclipse-inst
and
a window comes up with the TITLE
Eclipse Installer
An error has occurred. See the log file null.

====I don't know where that log file is.
Does Fedora 33 come with Eclipse 2020? Is it worth it or maybe I should stay with 2019, since I have the instruction as to how to install that version.

Navigate to the directory with the eclipse-inst executable in it. Right-click in the folder and open terminal. Run the executable from the command line.

I did not take the defualt install directory. It wanted to install in root. I wanted it a little more accessible and installed in my /home/<user id> directory.

OK, I installed it with
sudo ./eclipse-inst

I clicked on the Install C/C++ development thing
and I chose
/home/john/eclipse
and that is where it installed itself.

I looked in the Start menu. There is no Eclipse under Start -> Applications -> Development

Is that normal?

~~~~vmelkon

Yes, it's normal. With that particular install, you will need to navigate to the install directory and run the executable from there. Even though I chose the option to add shortcut to Start menu, it didn't for me either.

Alright, no start menu shortcut.

So,I went into
/home/john/eclipse/cpp-2020-12/eclipse/
using Dolphin
and I double clicked on
file = eclipse

And a message box comes up saying=
The Eclipse executable launcher was unable to locate its companion shared library.
With a large Close button.

Well, nothing prevents you from downloading eclipse.desktop from their git repository and installing it to ~/.local/share/applications or /usr/local/share/applications or wherever it would be used by your system.

shruggy has an answer that I haven't tried yet, but I got it to work via opening terminal in the directory where the eclipse executable lives and running the command:

shruggy’s answer will not work.
This is why I prefer people who have experience with the software in question: Eclipse.

The problem is that I ran the installer with sudo
sudo ./eclipse-inst
and this causes a mess.
The permissions on the folders are set as root and so, I cannot run Eclipse because of that.

For Qt Creator, I can install with sudo, and it properly installs, it creates a Start menu item and it works fine.
I think Qt Creator is a almost fully tested application while Eclipse is not.

I managed to clean things up and this time, I ran the installer as a regular user and installed in my /home/john
Now, the executable works.

I imagine Eclipse has had a few rounds of testing done in the last 20 years. However it is a Java application and its requirements and environment are different then a native application such as QT Creator.

Well, it would be nice if they documented how to install on Linux. What to do, what not to do.
Which distributions have been tested.
It helps to avoid wasting time.
Nobody seems to have a handle on how to install/uninstall applications on Linux.
