question about aliases and executable targets

[Warren Turkal]

Hi bazel experts,

I have a repo at https://github.com/wt/bazel_rules_nodejs.

I locally added the following line to examples/hello_world/BUILD:

alias(name="a", actual=":hello_world")

I was then able to successfully build ":hello_world" and ":a".

However, I am running into an issue with running the alias. The following command works:

bazel run :hello_world

However, the following fails:

bazel run :a

Here's the output::

examples/hello_world$ bazel run :a
ERROR: Cannot run target //examples/hello_world:a: Not executable.
INFO: Elapsed time: 0.174s
ERROR: Build failed. Not running target.

Should the alias not also be runnable?

Thanks,

wt

Ping? Does anyone have any ideas about this behavior?

Thanks,

wt

You just found a bug! I'm dabbling around in the alias rule right now anyway, so I thought I'll just fix this quick, but it does not seem to be a trivial one. I filed https://github.com/bazelbuild/bazel/issues/1290 .

Fix submitted for internal review. Should be there in tomorrow's push (or Monday's, if the push happens before the change is submitted)
