--java_debug doesn't work with "bazel run"?

[bend...@google.com]

Hi everyone!

The "--java_debug" flag is printed when I run "bazel help run", but it doesn't seem to have any effect? Is this a bug or am I missing something?

Thanks,

Michal

Hi Michal,

"bazel help <command>" shows you first a description of the command and how to use it followed by all the options available in bazel, grouped by category. The "--java_debug" flag is printed under "Options that affect how bazel runs tests". You may want to check what is under "Options specific to 'bazel run'". However, for debugging purposes you may need the startup option --host_jvm_debug, which you can find described if you run 'bazel help startup_options'.

I understand your confusion since 'bazel help' prints all the options regardless of the command you gave as an argument, but this is happening because most of them are compatible with all commands or just a subset and it should be understood from the description/category title how they should be used.

Cheers,

Irina

Thanks! It seems "bazel run :foo -- --debug" is the magic incantation I need.
