Circling back to the

AbstractMethodError

posted about ☝️, I have an example repo that reproduces the issue: https://github.com/traviscrawford/pantsbuild-repro-AbstractMethodError In that repo we do a clean build, use

sed

to rename a flag, then perform an incremental compile. Using

javap

we see the contents of one class in the deploy jar has the old flag name, and one class in the jar has the new class name. The repo has

./repro.sh

that scripts the process to reproduce, and

./output.txt

with the full output from running it locally. Any tips on how to resolve this issue? Today I learned about

PANTS_COMPILE_ZINC_INCREMENTAL=false

which I’ll set instead of manually `rm`’ing things, though ideally incremental would work.
