> The root cause of this is pants 0.0.32 expects a differently formatted
> {{pants.ini}} than the one we have now. Pants 0.0.32 ships with a migration
> tool that informs us of changes required. With a 0.0.32 pants source we can
> run:
> {noformat} PANTS_DEV=1 ./pants run src/python/pants/option:migrate_config --
> <pants.ini path>
> {noformat}
> This gives us:
> {noformat}
> Found java in section [thrift-gen]. Should be java in section [gen.thrift].
> Found extra_jvm_test_paths in section [ide]. Should be extra_jvm_test_paths
> in section [idea].
> Note: extra_jvm_test_paths now must be specified separately for idea and
> eclipse goals.
> Found python_test_paths in section [ide]. Should be python_test_paths in
> section [idea].
> Note: python_test_path now must be specified separately for idea and
> eclipse goals.
> Found python_lib_paths in section [ide]. Should be python_lib_paths in
> section [idea].
> Note: python_lib_path now must be specified separately for idea and eclipse
> goals.
> Found python in section [thrift-gen]. Should be python in section
> [gen.thrift].
> Found strict in section [thrift-gen]. Should be strict in section
> [gen.thrift].
> Found supportdir in section [thrift-gen]. Should be supportdir in section
> [gen.thrift].
> Found python_source_paths in section [ide]. Should be python_source_paths in
> section [idea].
> Found version in section [thrift-gen]. Should be version in section
> [gen.thrift].
> Found requirements in section [python-ipython]. Should be
> ipython_requirements in section [repl.py].
> Found indices in section [python-repos]. Should be indexes in section
> [python-repos].
> Found extra_jvm_source_paths in section [ide]. Should be
> extra_jvm_source_paths in section [idea].
> Note: extra_jvm_source_paths now must be specified separately for idea and
> eclipse goals.
> {noformat}
> Making the above changes to {{pants.ini}} results in some commands failing
> with {{Unable to detect a suitable interpreter}}. It isn't clear what needs
> to be done to fix that error. I suspect it has to do with some of the
> constraints in our {{pants.ini}} but I cannot determine which ones are at
> fault.
