./gradlew buildEdge fails despite successful EdgeApp-> Export in Eclipse

Hi all,
I started recently to work with OpenEMS. From within Eclipse I can run and export a functional edge app. I am now trying to get thegradle build to work form commandline with
./gradlew buildEdge
executed directly in the working copy. It fails with:

What could be the issue with that? Thanks for any insights!

EDIT: I just discovered that the the project io.openems.wrapper is the only one that uses sub-bundles (checkbox “enable sub-bundles” in io.openems.wrapper/bnd.bnd, option -sub: *.bnd in the bnd.bnd source). Do sub-bundles work with gradlew? Maybe this is the source of the error.

Best,
Bernd

Hi Bernd,

you need to execute ./gradlew build first.

This is what we do in our continuous integration build on GitHub Actions:

Hi Stefan, thanks for your support, much appreciated! I ran
./gradlew clean
./gradlew build
the last invocation failed with

etc.

Apparently it didn’t help. somehow the jar files are not built or not found for all the bnd sub-bundles in io.openems.wrapper

I there something else I can do to allow for better diagnosis? Provide any logs etc.?

After much try and error I tested with a fresh master checkout:
git clone https://github.com/OpenEMS/openems.git openems-master
cd openems-master/
./gradlew build

with the same errors:

Welcome to Gradle 7.0.2!

Here are the highlights of this release:

  • File system watching enabled by default
  • Support for running with and building Java 16 projects
  • Native support for Apple Silicon processors
  • Dependency catalog feature preview
