sbt.ivy.home and ivy.home properties both required

[nkijak]

Steps

• Create a project for developing a plugin using the scripted plugin.
• Run sbt scripted with sbt.ivy.home pointing to custom location that is not ~/.ivy2

Problem

• When the tests run they pull dependencies from a location not specified by sbt.ivy.home, failing tests because they are unable to find the jars published during the publishLocal step

Expectations

• The publishLocal task will place the plugin jar in the location specified by sbt.ivy.home
• The scripted tasks will run and dependencies will be pulled from sbt.ivy.home

Thanks for the report.

I'm thinking this can be fixed by forwarding the flag in the following line:

sbt/scripted/plugin/src/main/scala/sbt/ScriptedPlugin.scala

Line 81 in 0681649

scriptedLaunchOpts := Seq(),

I wonder if anyone else might be relying on older semantics.

@eed3si9n dont' let the scripted bit fool you. The core issue here is that we need to set BOTH flags in sbt, because of inconsistent usage.

See: https://github.com/sbt/sbt/blob/0.13/ivy/src/main/scala/sbt/Resolver.scala#L359 as an example of somethign which should be "sbt.ivy.home" for consistency...

Maybe ivy.home is trying to be consistent with Ivy? I would vote for respecting both with sbt.ivy.home having higher precedence.

Any update on this? I am experiencing the same issue as @nkijak. It appears that setting ivy.home and sbt.ivy.home in scriptedLaunchOpts does not help.

I've tried the following:

• ivy-home set to /drone/.ivy2/ via sbt.boot
• ivy.home and sbt.ivy.home set to /drone/.ivy2/ via scriptedLaunchOpts

My logs still show:

[info] 	published sbt-scalafix to /drone/.ivy2/local/ch.epfl.scala/sbt-scalafix/scala_2.10/sbt_0.13/0.2.0-RC2
....
[info] [warn] ==== local: tried
[info] [warn]   /root/.ivy2/local/ch.epfl.scala/sbt-scalafix/scala_2.10/sbt_0.13/0.2.0-RC2/ivys/ivy.xml

It works if I don't customize ivy.home, so my current plan is to re-arrange my ci to work that way.

This is a very confusing issue -- at the very least it should be documented better.

As @olafurpg points out, this makes it very difficult to run scripted tests in CI where you need to point to a custom ivy.home. Is there any workaround that someone has found?

This is what I tried to do for my situation:

export SBT_OPTS="-Dsbt.global.base=$CI_PROJECT_DIR/sbt-cache/.sbtboot -Dsbt.boot.directory=$CI_PROJECT_DIR/sbt-cache/.boot -Dsbt.ivy.home=$CI_PROJECT_DIR/.ivy"

Where CI_PROJECT_DIR is an env variable set by ci.
Then in scripted.sbt I added the following (because apparently SBT_OPTS aren't respected by the scripted task):

scriptedLaunchOpts := { scriptedLaunchOpts.value ++
    Seq("-Xmx1024M", "-Dplugin.version=" + version.value) ++
    // append SBT_OPTS so scripted launches with the correct cache dirs
    sys.env.get("SBT_OPTS").map(x => x.split(" ").toSeq).getOrElse(Nil)
}
scriptedBufferLog := false

This worked for most of the plugin projects I have been working on, but recently started failing again during a refactor.

After some investigation into that project, I found that the particular issue was due to scoping issues. Inspecting the value of scriptedLaunchOpts for the actual plugin project, revealed that it was missing my passthrough for SBT_OPTS. Adding those settings to my project specific settings made everything resolve properly after that.

I hope this helps someone else running into a similar issue with a custom sbt.ivy.home and running scripted tests for sbt plugins.

I guess we can just drop ivy.home support and use sbt.ivy.home here - https://github.com/sbt/librarymanagement/blob/da6897b8a3d4e08d5cfce9589c18b8ae5bff0641/core/src/main/scala/sbt/librarymanagement/ResolverExtra.scala#L395

[kterusaki]

any update on this? As @a1kemist has pointed out, this the scripted plugin useless if we can't run it in CICD where we need to point to a custom sbt.ivy.home.

I have the following as my scriptedLaunchOptions:

scriptedLaunchOpts := {
    scriptedLaunchOpts.value ++
      Seq("-Xmx1024M", "-Dplugin.version=" + version.value, "-Dsbt.ivy.home=" + sys.props.get("sbt.ivy.home"))
  }

And I'm passing the sbt.ivy.home system property to sbt like so:

sbt -Dsbt.ivy.home=$HOME/.ivy-custom/ scripted

The error output is:

....
	Note: Unresolved dependencies path:
[info] [error] sbt.librarymanagement.ResolveException: Error downloading my.org:my-project;sbtVersion=1.0;scalaVersion=2.12:5.0-SNAPSHOT

The sbt.ivy.home system property is treated as a relative URL to the tmp directory used to scope the sbt plugin test. I'm not sure what the right fix is here. If everything needs to be scoped by the /private/var/... directory then maybe the scripted plugin should copy the local snapshot to this folder?
