[Reproducible-builds] maven.build.timestamp and ReproducibleBuilds with maven

[Eugene Zhukov]

Hi,

I'm trying to make epubcheck package build reproducibly. It has property:
<tool.build.date>${maven.build.timestamp}</tool.build.date>
in pom.xml which messes up reproducibility.
I use debhelper from [1] to build it and SOURCE_DATE_EPOCH environment
variable at hand.
Still I struggle to pass it dynamically at build time to
${tool.build.date} or ${maven.build.timestamp}.
It is possible to set tool.build.date=something in d/maven.properties,
but how to get this done dynamically?

Thanks,
