Also, which goal matters a lot

bored-art-40741

Only 3 goals use the jvm subsystem

In our internal build, this

./pants test.junit --jvm-debug --jvm-debug-port=5959 iago:tests -ldebug

still listens on port 5005

we're on an older SHA tho

witty-crayon-22786

07/31/2015, 11:10 PM

...well,

--jvm-test-junit-debug

is least ambiguous

billowy-alarm-80641

07/31/2015, 11:10 PM

right, I tried that form too

billowy-alarm-80641

07/31/2015, 11:11 PM

I don't think this is a big deal -- I'll document it as an errata for our release

Okay, I have one more -- in OS pants master:

Copy code

[prometheus pants (master)]$ ./pants repl -h --help-advanced|grep -A 1 '\-options'
--jvm-repl-scala-options=<option>... (--jvm-repl-scala-options=<option>...) ... (default: ['-Xmx1g','-XX:MaxPermSize=256m','-Dscala.usejavacp=true'])
    Run with these extra JVM options.

looks like a transient thing

happy-kitchen-89482

Yep, retrying made everything go green

@happy-kitchen-89482: with regards to cached chroots (https://rbcommons.com/s/twitter/r/2486/)... do we expect repeated invocations of

./pants run

to invalidate the cached chroot if source files change?

mammoth-autumn-2551

08/03/2015, 2:27 AM

i.e. if I run

./pants run src/python:foo

, then change the contents of the

foo

target, and rerun, will it use the cached chroot (and miss the updated changes)?

enough-analyst-54434

If the chroots don't invalidate as expected, that's a bug. What change do you make, deps or sources or other?
