deb install - sbtopts location

[yurique]

steps

• install via deb channel (https://dl.bintray.com/sbt/debian)
• run sbt -h

Usage:  [options]
// ...
  /etc/sbt/sbtopts   if this file exists, it is prepended to the runner args
// ...

• edit /etc/sbt/sbtopts and add some settings
• run sbt

problem

The parameters from the /etc/sbt/sbtopts are not applied.

expectation

The parameters from /etc/sbt/sbtopts to be applied.

notes

In the /usr/bin/sbt there's this

declare -r etc_sbt_opts_file="${sbt_home}/conf/sbtopts"

so it looks for sbtopts file in /usr/share/sbt/conf/sbtopts - putting the settings there actually works.

But when sbt package gets updated /usr/share/sbt/conf/sbtopts gets overwritten.

I'm sorry for bothering anyone seeing this again, but this one is bad. Today apt upgrade updated the sbt package without me noticing it.

I started getting java.lang.OutOfMemoryError: Metaspace when running tests - walked through a dozen of files to see where I might have broken thingst. And it turned out that the /usr/share/sbt/conf/sbtopts was silently replaced by the default one from the deb package and OutOfMemoryError was coming from the now-missing memory settings for sbt :)

It's me again, sorry. Got another update from the deb channel and it's overwritten my sbtopts again. Should I report this somewhere else?

Hi, it hasn't been a priority to look into this. I just set environment variable like SBT_OPTS.

The relevant bits are here (https://github.com/sbt/sbt-launcher-package/tree/master/src/universal/bin) if you'd like to look into fixing it, or suggest a fix.

@eed3si9n, thanks for pointing me to that location! I've created a PR to fix this issue:
sbt/sbt-launcher-package#179

it hasn't been a priority to look into this

Of course, it was a busy summer for sbt :)

Thanks again for the contribution!
Fixed in sbt/sbt-launcher-package#179
