tycho: Tycho 3.0.0 fails to build - java.lang.NoSuchMethodError: void org.eclipse.equinox.internal.p2.repository.helpers.ChecksumProducer

I use Tycho 3.0.0 to build our RCP app. Today it no longer works resulting in this error:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-p2-repository-plugin:3.0.0:assemble-repository (default-assemble-repository) on project com.archimatetool.editor.product: Execution default-assemble-repository of goal org.eclipse.tycho:tycho-p2-repository-plugin:3.0.0:assemble-repository failed: An API incompatibility was encountered while executing org.eclipse.tycho:tycho-p2-repository-plugin:3.0.0:assemble-repository: java.lang.NoSuchMethodError: ‘void org.eclipse.equinox.internal.p2.repository.helpers.ChecksumProducer.<init>(java.lang.String, java.lang.String, java.lang.String)’

I haven’t changed anything. ~It works OK on Windows and Mac Intel.~

Here is our main pom:

https://github.com/archimatetool/archi/blob/master/pom.xml

And the one for the *.product file:

https://github.com/archimatetool/archi/blob/master/com.archimatetool.editor.product/pom.xml

Using Tycho 3.0.0

I have no idea what could be causing this. I’ve deleted the .m2 directory and still the same result.

Did something change upstream?
