No 32bit Eclipse any more for v4.10? What to use for 32bit Java? [message #1803021] Thu, 21 February 2019 06:59 Go to next message

In the past I always installed a 32bit Eclipse version since it is required for my 32bit Java installation.

When I look now at the Eclipse download page:
https://www.eclipse.org/downloads/packages/release/2018-12/r

then there is no more 32bit Eclipse to download.
Where is it?

Can I use now 64bit Eclipse IDE WITH 32bit Java JDK?

Or am I forced to switch to 64bit Java JDK?

Hi

Eclipse abandoned 32 bit support because Oracle abandoned it. There is no 32 bit JDK 11.

If you want old technology use it consistently.

Ok, thank you.

Assume I want to switch to 64bit (on 64bit Win7).
Can I simply

1. de-install 32bit JDK + install 64bit JDK
2. de-install 32bit Eclipse + install 64bit Eclipse
3. Point the new Eclipse installation to the old,existing, personal workspace (created with 32bit Eclipse)?

In other words: is my workspace (with all the settings files) compatible between 32bit and 64bit?

HI

The workspace is a workspace; it is neither 32 nor 64 bit.

You don't need to uninstall anything, except to save space / avoid confusion.

You just need to ensure that the Eclipse you start uses a consistent VM. See the config guides. I prefer to specify the VM on my Windows short cut. You may prefer to edit eclipse.ini. Google for many recommendations.
