#18810 `adhoc_tool` `stdout` and `stderr` are relative to build root, not workdir Issue created by huonw Describe the bug The

stdout

and

stderr

fields are documented as being relative to the workdir, the same as

output_files

and

output_directories

, but are currently relative to the build root: pants/src/python/pants/backend/adhoc/target_types.py Lines 147 to 166 in </pantsbuild/pants/commit/a39c1b970be2cb4421b20728c21c3222aeb4b015|a39c1b9> Reproducer, with the

output_files

version for comparison:

version is at the top level of the chroot: it should match the

version, being within
