Hi. In case it matters, it also fails in Salsa CI: https://salsa.debian.org/sanvila/groovycsv/-/pipelines
I also did a debbisect and can tell when exactly this started to fail: bisection finished successfully last good timestamp: 20251024T143326Z first bad timestamp: 20251025T023803Z the following packages differ between the last good and first bad timestamp: libspock-java 0.7-groovy-2.0-4 -> 1.0+dfsg-1 libxml2-16:amd64 2.14.6+dfsg-0.1 -> 2.15.1+dfsg-0.2 If it really works for you using sbuild, please post the full build log. Thanks.
