Help needed with Bndtools Eclipse Installation

GENERAL
1

I have a legacy OSGi project that is currently developed with Java 8 in an Eclipse Mars installation with Bndtools 3.5.

The goal is, to get the project running on an as-recent-as-possible Java version.

The latest known-to-work-with-the-project Bndtools version is 4.0.0 from an earlier attempt six years ago. Unfortunetly version 4.0.0 seems to be no longer publicly available. For that reason I set-up an Eclipse 2023-03 with Bndtools 4.3.0. But now I’m stuck getting the following error on build in my Eclipse log:

I’m not able to track the root cause of the problem. Any help/hint is appreciated.

Side question: Is Bndtools 4.0.0 Eclipse plug-in still available anywhere? Maybe this would help migrating the project in as little steps as possible.

Hi,
the Stacktrace suggests, that one of the Paths of an OSGIRepository has a bogus path. It is likely that something in the way how paths are handled has changed since 3.5. Maybe something starting with // instead of file://.

4.0 should be available somewhere, but I have no clue where. If you want to update to a newer java anyway, I suggest you jump to 7.0 (requires Java 17 to build) und go to 6.4 (still builds with a JDK 8). Besides minor things like this, thinks should still work as before.

URI has an authority component

As @juergen-albert suggested, have a look somewhere in your cnf folder e.g. cnf/build.bnd and check for paths of your repository definitions. Maybe an old url pointing to a shared "windows network drive URL somewhere starting with \\?)

Thanks for your reply, but I cannot find any such explicit URIs in the project.

Can you post all the -plugin instructions you have in your cnf/buid.bnd and in all the .bnd files in your cnf/ext/ folder?
