Hello,
as I am updating my binding since yesterday, I get since today the following error. Yesterday it was still working fine. The pom.xml in the binding is throwing this errors on the

<parent>

my pom.xml looks like the folllowing:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

</project>

In the console I get this error now and I cannot launch my environment anymore.

I still don’t know what caused the problem. I guess it is related with this topic and the build of a binding compatible with an older version. However after I cleaned .m2 and .p2 folder and made a reinstall it worked again.

You need to checkout also openhab-core and build it or configure remote maven repositories to fetch openhab 4.0 snapshots. Error message you got says that your binding can not find dependency org.openhab.core.bundles:org.openhab.core.test:jar:4.0.0-SNAPSHOT. It comes from openhab core so I suppose you switched your addons to main branch but did not build openhab-core main branch yet.

If your connection to the openHAB repo works again you can make it reattempt to download snapshot artifacts before the update interval expires (usually at midnight) by telling Maven to do so by adding the -U (or --update-snapshots) switch to your command:

 -U,--update-snapshots                  Forces a check for missing
                                        releases and updated snapshots on
                                        remote repositories

E.g.:

mvn clean install -U

If you don’t work on openhab-core you don’t need to clone or build it because then Maven will just download and use the artifacts produced by the Jenkins CI job.
