[Android-tools-devel] Bug#1147930: Several java packages make autobuilder to hang with an endless stream of "Gradle is still running, please be patient..."

Package: src:adql src:android-platform-tools-apksig src:barclay src:capsule-maven-nextflow src:capsule-nextflow src:darcula src:dom4j src:gatk-fermilite src:gkl src:htsjdk src:igv src:libhamcrest-java src:libhttp-nio-java src:libjdom2-intellij-java src:milib src:opentest4j src:vdjtools src:xgboost-predictor-java

Dear maintainer:

I'm getting persistent build failures when trying any of the above packages because autobuilder hangs.

I'm filing a single report because this is likely a bug in one of the build-dependencies,
but I don't know which one. (I request help to determine which one and reassign
accordingly).

This is how the build typically fails, the example is taken from "src:adql":

and at this point I have to kill dpkg-buildpackage by hand, because sbuild is not brave enough to do so.

Most probably this started to happen somewhere between 2026-09-06 and 2026-09-13.

I've put sample build logs here for reference:

Thanks.
