Thanks for your help at the weekend - it solved that issue, but I now seem to have the problem the other way around:
... :bson:checkstyleMain Replacing com.puppycrawl.tools:checkstyle:jar:6.2 -> com.puppycrawl.tools:checkstyle:jar:debian Passing through org.apache.commons:commons-lang3:jar:3.x POM relocation to an other version number is not fully supported in Gradle : org.apache.commons#commons-lang3;3.x relocated to org.apache.commons#commons-lang3;debian. Please update your dependency to directly use the correct version 'org.apache.commons#commons-lang3;debian'. Resolution will only pick dependencies of the relocated element. Artifacts and other metadata will be ignored.

FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':bson:checkstyleMain'. > java.lang.NoClassDefFoundError: org/apache/commons/lang3/ArrayUtils This seems to be similar to this problem: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=832869 which was apparently fixed by this commit: https://anonscm.debian.org/cgit/pkg-grass/osmosis.git/commit/?id=371579dab27e3dda4ee3b0e39673c328979989c8 I've tried adding the line: org.apache.commons commons-lang3 * s/.*/debian/ * * to my debian/maven.rules file, but still get the same error message. Interestingly, if I build the package on Ubuntu Xenial (which has libcommons-lang3-java 3.4-1) I don't get this problem, presumably because the 'debian' version was only added in 3.4-2. Thanks for any suggestions. Christopher
