Use newer Eclipse than Luna (which is released on 2015)

[130s]

Only reason to fall back on an older version, Luna or 4.4, is that functioning XML editors might not be available in newer Eclipse version (confirmed with XMLEspresso and WTP on Mars2, Neon).

• People are complaining about XMLEspresso

But it's such an annoyance to bear with an old version without any update, while people are excited about newer IDE, e.g. VSCode. Time to look into Eclipse 4.15 or newer.

Another reason to use Luna #88.

On serval I just replaced the version with Luna manually.

$ ll `which eclipse`                                         
lrwxrwxrwx 1 root root 47 Jul  8  2016 /usr/bin/eclipse -> /usr/share/eclipse/eclipse_mars2_nogood/eclipse*
$ sudo rm /usr/bin/eclipse

$ ll `which eclipse`

Installed CDT of Eclipse 202006 version. Then installing pydev returns:

    To: org.eclipse.equinox.p2.iu; org.eclipse.tools.templates.freemarker.java11 [1.1.100.202001140305,1.1.100.202001140305]
  Cannot satisfy dependency:
    From: Template Engine Freemarker Support (Java 11) 1.1.100.202001140305 (org.eclipse.tools.templates.freemarker.java11 1.1.100.202001140305)
    To: osgi.ee; (&(osgi.ee=JavaSE)(version=11))

According to https://stackoverflow.com/questions/62648135/error-installing-devstype-plugin-for-eclipse this error is not due to java version but it's just CDT's bug. Indeed.

So far so good:

• pydev seems good.
• emacs keybind seems already activated without doint any preference setting.
• xml rendering good so far (verified with launch file).

Added multiple plugins and eclipse started not launching. I ended up re-installing the entire eclipse 202006. I could have just tried removing some/many plugins from .plugins folder.

That was an annoyance, but other than that, so far 202006 seems to be working ok. I like they added dark background.
