simplify the update site and download URLs

[martinlippert]

The Spring Tools 5 major release gives us the chance to simplify the update and download site URLs.

At the moment, we have for releases:

• https://cdn.spring.io/spring-tools/release/TOOLS/sts4/update/latest/
  • composite pointing to the latest release
• https://cdn.spring.io/spring-tools/release/TOOLS/sts4/update/4.31.0.RELEASE/e4.37
  • the concrete update site of a specific release for a specific Eclipse base release
• https://cdn.spring.io/spring-tools/release/STS4/4.31.0.RELEASE/dist/e4.36/spring-tools-for-eclipse-4.31.0.RELEASE-e4.36.0-macosx.cocoa.aarch64.dmg
  • for a specific distribution package release

For snapshots:

• https://cdn.spring.io/spring-tools/snapshot/TOOLS/sts5/nightly/e4.37
  • snapshot build for a specific Eclipse base release
• https://cdn.spring.io/spring-tools/snapshot/STS5/nightly/dist/e4.37/spring-tools-for-eclipse-5.0.0.202507091848-SNAPSHOT-e4.37.0-macosx.cocoa.aarch64.dmg
  • for snapshot distribution builds

I would like to simplify this down to:

Release update sites:

• https://cdn.spring.io/spring-tools/release/update/latest/
• https://cdn.spring.io/spring-tools/release/update/4.31.0.RELEASE/e4.37

Snapshot update sites:

• https://cdn.spring.io/spring-tools/snapshot/update/e4.37

Release distributions:

• https://cdn.spring.io/spring-tools/release/dist/4.31.0.RELEASE/e4.36/<distribution-package-file>

Snapshot distributions:

• https://cdn.spring.io/spring-tools/snapshot/dist/e4.37/<distribution-package-file>

Since we are having sts4 and sts5 snapshot builds and probably need to make them both available then

Snapshot Update Site:
https://cdn.spring.io/spring-tools/snapshot/update/e4.37 unlikely what we want.

The rest seems to be okay... Are we going with these URL path changes for the main branch only? Or 4.x should be aligned?

[martinlippert]

From my point of view, the update sites for the 4.x branch and builds should not be changed, so that users will get snapshot and release builds from the known locations and don't need to change anything in their existing installations.

Not sure I understand your concerns here. The 4.x snapshots would continue to be updated at:

https://cdn.spring.io/spring-tools/snapshot/TOOLS/sts4/nightly/e4.37

whereas the new 5.x snapshots should be available via:

https://cdn.spring.io/spring-tools/snapshot/update/e4.37

[BoykoAlex]

@martinlippert I was under the impression that sts4 and sts5 snapshot update site would have been the same. NVM, I see that they are different now. Yes, I can implement this change.

What shall we do with some URLs not facing the user directly, i.e.
https://cdn.spring.io/spring-tools/release/TOOLS/sts4-language-server-integrations/2025-06-05

Should this become:
https://cdn.spring.io/spring-tools/release/language-server-integrations/2025-06-05

The snapshot for Eclipse LS extensions has path: snapshot/TOOLS/sts5-language-server-integrations/nightly I'd change this similarly to snapshot/language-server-integrations/nightly?

I will also go ahead and remove this site from the p2 auto-config, so that this doesn't end up in the distribution packages automatically anymore.

[martinlippert]

I would also go ahead and remove the product definitions for older Eclipse base versions. Spring Tools 5 should initially ship for Eclipse 2025-09 and that's it. Which also means we can remove/disable builds for older Eclipse base versions for now.

For future releases of Spring Tools 5, we should then go back to ship releases for the previous Eclipse base version as well again.
