You will need to include some options to run various programs. Here are some samples, but the directories may vary depending on your configuration. Standard Gorp -Dfile.encoding=UTF-8 -Xmx3000m -DCLDR_DIR=${workspace_loc}/cldr -DOTHER_WORKSPACE=${workspace_loc}/"../Google Drive/workspace/" -DCLDR_GEN_DIR=${workspace_loc}/"../Google Drive/workspace/Generated/cldr/" -Dregistry=language-subtag-registry -DSHOW_FILES The xmx is to increase memory so that you don't blow up. If you only do a few dozen locales, you don't need to set it that high. Optional -f regex // to only check locales matching the regex, like ".*" or "en|fr|de" ... -DSHOW_FILES // shows files being opened and created |
