[SOLVED] Resolving Plug-In Dependency on org.eclipse.equinox.p2.iu in Eclipse 2021-12

I am trying to get an Eclipse plugin (originally developed for Eclipse Neon and Java 8) working and cannot load in the target platform. My system config is as follows:

Machine: 2021 MacBook Pro (M1 Pro)
Java Version: Java SE 17.0.1 (also tried JDK 8 Temurin)
Eclipse 2021-12 (4.22.0) (although I have also tried installing Eclipse Neon on this machine and got the same problem)

When I try to load in the target platform (included at the bottom of the post) I get the following errors:

Problems occurred while resolving the target contents
    Cannot complete the install because one or more required items could not be found.

Thanks in advance for any help.

EDITS:

@greg-449 was correct in pointing out the conflicting architectures. I was originally running on aarch64, but when I downloaded x86_64 Eclipse/Java, the plugins resolved. However, now I have a different issue, still related to conflicting architectures. When trying to launch my plugin:

    /Users/austin/eclipse-workspace/visuflow/.metadata/.plugins/org.eclipse.pde.core/New_configuration/org.eclipse.osgi/132/0/.cp/libswt-cocoa-4628.jnilib: dlopen(/Users/austin/eclipse-workspace/visuflow/.metadata/.plugins/org.eclipse.pde.core/New_configuration/org.eclipse.osgi/132/0/.cp/libswt-cocoa-4628.jnilib, 0x0001): tried: '/Users/austin/eclipse-workspace/visuflow/.metadata/.plugins/org.eclipse.pde.core/New_configuration/org.eclipse.osgi/132/0/.cp/libswt-cocoa-4628.jnilib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/lib/libswt-cocoa-4628.jnilib' (no such file)

For anyone who has similar problem for:

requires 'org.eclipse.equinox.p2.iu; org.eclipse.equinox.util 1.0.400'

First solution: I would recommend checking which Eclipse version you have installed. I installed the newest and by default and I got 'Eclipse IDE for Java Developers' from the official Eclipse page. If you spend 2 more minutes you can find 'Eclipse IDE for Enterprise Java and Web Developers' - it is more advanced and it looks like some plugins work only on this version.

Second solution: Add to "Available Software Sites" new site name: Eclipse Oxygen.2 URL: http://download.oracle.com/otn_software/oepe/library/eclipse-oxygen.2

I tested the above solutions and both of them work for me. Cheers.
