Unable to import as source project in PDE

[RedeemerSK]

While doing some Eclipse development I ended up needing to see source code of 'org.eclipse.tm4e.ui' plugin. As previously with other plugins, I expected to be able to just import as source project from plugins view. In case this expectation is unjustified, let me know, I'm no expert in Eclipse plugins development.

Project was however not imported with source code, but just with binary JAR of itself (as a referenced library of created project).

Eclipse PDE Latest (2025-03 M1 (4.35.0 M1)), fully updated. org.eclipse.tm4e.ui version: 0.14.1.202412182118 (atm latest from https://download.eclipse.org/tm4e/snapshots/). Target platform set to "Running platform".

I can only guess that "Eclipse-SourceReferences" in MANIFEST.MF is used when importing project for plugin, and the "path" there seems ok to me. Only the whole MANIFEST.MF file is not formatted according to spec, but it may not be the cause.

TBH I have no idea. @mickaelistria WDYT?

Import As > Source Project would only work if you have the source bundle available too IIRC. If you want to import using the Eclipse-SourceReferences (which is best), you should try "Import As > Project from Repository...".

I've open https://github.com/eclipse-pde/eclipse.pde/pull/1556 to hopefully provide better guidance from the plug-in view.

and also https://github.com/eclipse-pde/eclipse.pde/issues/1557 was one cause here.

@mickaelistria Can we close this issue or is there anything we can do in TM4E?

[mickaelistria]

Yes, let's close it here.
