Is it advantageous to install multiple applicable Eclipse IDEs?
Additional functionality?

Or should ONLY 1 Eclipse IDE be installed (due to [stability / conflict]
reasons): install 1 IDE and the balance be Packages/Features.

I see in the updates that both IDEs and Packages/Features appear to be a valid
download (see below).
Please advise.
Thanks, Tracey

1 Eclipse IDE for Automotive Software Developers
1 EPP Automotive Feature
2 Eclipse IDE for C/C++ Developers
2 EPP CPP Feature
3 Eclipse IDE for Java Developers
3 EPP Java Package

You can explode as many copies of Eclipse and in as many flavors as you
can tolerate giving up disk to.

Loaner? Eclipse does not make use of licensing.

Russel is right, you can have as many Eclipse installations as you want. Having said that, it doesn't make a lot of sense to have some of them when you have others. For example, "Eclipse IDE for Java Developers" and "Eclipse IDE for Java EE Developers" are similar in that the Java EE one is a superset of the other; there's no need to have both if you have the Java EE package.

Where does that list come from? Some of those names aren't familiar?

So [Jave EE Developers] also does what [Java and Report Developers] and [Java
Developers] can do?

When I open the Add New Software and filter by "Eclipse IDE for Java" I get
Eclipse IDE for Java and Report Developers
Eclipse IDE for Java Developers
Eclipse IDE for Java EE Developers

Sorry for the type-o, I meant loner (I did not see a matching pair: IDE &
Feature for Java EE).

Just to clarify, Eclipse does make use of licensing, and in fact only exists because of it. It instead does not impose of the sort of restrictions that typically accompany commercially licensed software.

Some of the [Eclipse IDEs] also seem to have a corresponding [Package].

If there is already some other IDE installed, does just adding the Package give
the same functionality as the corresponding IDE?
I assume yes, but I may be wrong.

For Example:
The [Eclipse IDE for Java Developers] also appears to have a corresponding
Package [EPP Java Package] (I assume they are the same thing).
The [Eclipse IDE for Java EE Developers] does NOT appear to have a corresponding
Package.

So, if I want the functionality of both the [Eclipse IDE for Java Developers]
and the [Eclipse IDE for Java EE Developers] then I install the [Eclipse IDE for
Java EE Developers] then add the [EPP Java Package] :-)

Am I correct?
Please advise.
Thanks, Tracey

I think you're a bit confused about packages and features. It's a long story, but the short version is that the Eclipse "packages" are what you see on the main downloads page, things like "Eclipse IDE for Java Developers." Each of those packages are assembled from a specific collection of Features (and, in turn, a Feature is a collection of Plugins/Bundles). The download packages you see at https://www.eclipse.org/downloads/ are produced by the Eclipse Packaging Project (EPP), which is just another project under the Eclipse Foundation umbrella; it just so happens to be highly promoted on the eclipse.org web site as the "official" downloads. What you see labeled as "Eclipse IDE..." are the packages, just with friendly names.

You're correct that you can start with any Eclipse package (or just the bare platform if you really want to DIY) and add Features and/or Plugins to assemble a custom installation; that's how Eclipse is designed to work. It's just that, for the vast majority of people, one of the EPP packages from https://www.eclipse.org/downloads/ is usually the best choice.

To answer your last question, The "...Java EE Developers" package is a superset of the "...Java Developers" package, so you don't need to install it separately.

I would like an answer to my question. In another thread in another part of this forum, I keep coming to a thread I started weeks ago, & I am only answering myself. Like I have any answers. Not only very boring, I am not getting anywhere.

I understand this about Eclipse. Yet I keep finding conflicts & don't know how to resolve them.

Basically, I need to know which versions of Eclipse IDE (packages) can share with each other.

I am a C/C++ developer that wants to have modeling features like Papyrus, UML/SysML. At the same
time, I would like Java&JavaEE, Java & DSL, Java & BIRT, PHP, Xtext, Xpand, Xtend, RCP & Rap, Scout,
Automotive Embedded, BPMN, PTP on one IDE.

I have had some success with Luna (4.4M7), yet not so good with Kepler SR2 (4.3.2). On Kepler, I find
that RCP/RAP or Scout do not like something already installed (currently don't know what or how to find
out). For either Kepler/Luna this is after making the JVM Heap size really Huge (like just shy of 2GB).
For Luna I got all the above installed and now RC2 just got released. I may wait till RC3 / Release before
I change. In any case, on Luna above, I had a problem with Object Team (OTDT) and I figured out how to
remove it. Good, now how do I reinstall it?

I also noticed that CDT is currently only upto 8.3.0 (Kepler SR2) and not to 8.4.0 (Luna) yet I have the
major portion of CDT installed. I don't know what I am missing. I guess I have to wait till 6/25 for that...

I finally got a release schedule on the main packages for Luna. So I will keep my eye peeled. I know I may
be rambling though if you could give guidance on which IDE to start with for Kepler SR2 or later if it is
really true that RCP/RAP need special consideration. If I started with that IDE built from that...

Oh & just to be clear, I am using a Cocoa-x86-64 bit install, for an iMac mid-2011, 4GB memory, Mac OS X 10.9.2.
I didn't want to have more than two versions of Eclipse while I use it.

One more thing: I like to know looking at my doc at the app I'm starting to tell me which version it is. So I
discovered, if I just rename this app that this can eventually cause problems. Is their some config switch or
something I need to address in either the ini file in the configuration folder or within the app itself??

Thanks in advance... Wink

ps: I also need to have best support available for Perl, Python, D Language, Scala, & VHDL.
