Official Repository does not run github actions

c.lehne · May 11, 2026, 5:04pm

For anyone currently having trouble with GitHub Actions in the official or in your own OpenEMS-GitHub repository:

I provided a new PR #3725 providing at least a workaround for the issue.

The reason is the maven repository, which is behind a Cloudflare server and the Cloudflare server is blocking requests (see PR comment).

Hope this helps someone.

I’m not going to mention, how long it took me to find this out today ;-(.

For the sake of completeness: Error looked like that:

..

* What went wrong:

Thank you Christian,

me and our team also spent hours yesterday on that problem… I did not read about anybody else in the world having problems with Maven Central on OSGi/bndtools builds.

Thank you for providing a workaround. We came up with something similar eventually (self-hosted NGINX proxy…)

I will not merge immediately because I would prefer staying with the defaults; but might do so before the next release on 01st of June.

It seems the problem is caused by an invalid User-Agent header. bndtools is sending a different User-Agent than the original maven. Afterwards, the IP address from this request gets blocked.

Original maven is overriding the USER_AGENT for the maven-resolver, which leads to a User-Agent “Apache-Maven…”

github.com/apache/maven

impl/maven-core/src/main/java/org/apache/maven/internal/aether/DefaultRepositorySystemSessionFactory.java

master


      
          Map<String, String> mergedProps = createMergedProperties(request);
          
          boolean mavenMaven3Personality = Features.mavenMaven3Personality(mergedProps);
          MavenSessionBuilderSupplier supplier = new MavenSessionBuilderSupplier(repoSystem, mavenMaven3Personality);
          SessionBuilder sessionBuilder = supplier.get();
          sessionBuilder.setArtifactTypeRegistry(new TypeRegistryAdapter(typeRegistry)); // dynamic
          sessionBuilder.setCache(request.getRepositoryCache());
          
          // configProps map is kept "pristine", is written ONLY, the mandatory resolver config
          Map<String, Object> configProps = new LinkedHashMap<>();
          configProps.put(ConfigurationProperties.USER_AGENT, getUserAgent());
          configProps.put(ConfigurationProperties.INTERACTIVE, request.isInteractiveMode());
          configProps.put("maven.startTime", request.getStartTime());
          configProps.put(Constants.MAVEN_START_INSTANT, request.getStartInstant());
          
          sessionBuilder.setOffline(request.isOffline());
          sessionBuilder.setChecksumPolicy(request.getGlobalChecksumPolicy());
          sessionBuilder.setUpdatePolicy(
                  request.isNoSnapshotUpdates()
                          ? RepositoryPolicy.UPDATE_POLICY_NEVER
                          : request.isUpdateSnapshots() ? RepositoryPolicy.UPDATE_POLICY_ALWAYS : null);

Bndtools is not providing this key in the maven-resolver session, which leads to default “Aether”. I think we are not able to override this User-Agent without changing bndtools Sourcecode. We would need to add the Maven User-Agent here: bnd/biz.aQute.bnd.maven/src/aQute/bnd/maven/lib/resolve/RemotePostProcessor.java at master · bndtools/bnd · GitHub

Currently I see the following solutions:

Use a reverse proxy to modify the User-Agent before sending the request to Maven
Hope that Maven or Cloudflare is removing the User-Agent checks again
Modify bndtools source and add the User-Agent
Use a different maven central repository or host our own

@stefan.feilmeier I too face the similar issue in the git action workflows.
Then I wanted to check local docker build, but problem persist, then I checked from the openems develop branch, still same issue I guess:

When I do - docker build -t oems-edge -f tools/docker/edge/Dockerfile . (in the locals)
I see this:

I created a Issue at bndtools: Maven Central is blocking our IP address when we use maven via bndtools · Issue #7228 · bndtools/bnd · GitHub

nishad · May 15, 2026, 10:54am

Hi,

Any solution to this ?
Atleast from the local build I wish to build it successfully,
Should I take the cnf folder from the recent build ? How to fix this both locally and on the git actions ?

stefan.feilmeier · May 15, 2026, 11:26am

It seems builds are working again now - see Workflow runs · OpenEMS/openems · GitHub

nishad · May 15, 2026, 11:49am

@stefan.feilmeier
Thank you so much for a quick response.

Yes I saw,
I made recent change, I took the cnf/build.bnd from the recent build.
And the build actually failed with these:
