pack build panics on Travis #102

Closed scothis closed 5 years ago

scothis commented 5 years ago

Building and running pack on travis-ci results in a panic, while the same source and command passes on mac OS.

$ pack build foo/bar --builder projectriff/builder:0.2.0-snapshot-ci-912b954091ca --run-image packs/run:v3alpha2 --path fats-uppercase-java-boot/

I've managed to work around this issue by pinning the code producing the index out of bounds. I'm still not sure as to the root cause.

replace github.com/Nvveen/Gotty => github.com/ijc/Gotty v0.0.0-20170406111628-a8b993ba6abd

...seems a shame to replace 7 year old code with 2 year old code.

I'm seeing this on my dev machine too when I built from f38cbcc8717b62c82140a937a87a090da9745114
