cannot add a resolver from within a script

[dportabella]

This works good:

$ amm
Loading...
@ val oss = Resolver.Http(
    "ambiata-oss",
    "https://ambiata-oss.s3-ap-southeast-2.amazonaws.com",
    IvyPattern,
    false
  )
@ interp.resolvers() = interp.resolvers() :+ oss
@ import $ivy.`com.ambiata::mundane:1.2.1-20141230225616-50fc792`
import $ivy.$

However, this fails:

cat >script <<'EOF'
import ammonite._, Resolvers._

val oss = Resolver.Http(
  "ambiata-oss",
  "https://ambiata-oss.s3-ap-southeast-2.amazonaws.com",
  IvyPattern,
  false
)

interp.resolvers() = interp.resolvers() :+ oss

import $ivy.`com.ambiata::mundane:1.2.1-20141230225616-50fc792`
EOF

For some reason, interp.resolvers() = interp.resolvers() :+ oss is not taken into accound when run from within a script.

Note: I need this to create a script with the #!/usr/bin/env amm header.

Having exactly the same issue.

[lihaoyi]

The problem here is that the resolvers only get added when the code executes, but the import $ivy takes effect before the code executes.

A workaround would be to put the resolver-mangling into a separate compilation block, using @ to split the file in two:

import ammonite._, Resolvers._

val oss = Resolver.Http(
  "ambiata-oss",
  "https://ambiata-oss.s3-ap-southeast-2.amazonaws.com",
  IvyPattern,
  false
)

interp.resolvers() = interp.resolvers() :+ oss

@

import $ivy.`com.ambiata::mundane:1.2.1-20141230225616-50fc792`
...

Perhaps at some point we can add a magic import $resolver that can do this for us and let us avoid the annoying @

[dportabella]

cool, I didn't know about "compilation blocks"!
however I tried this and it fails with the same error.

[dportabella]

@Eli-Golin, does the solution proposed by @lihaoyi work for you?

[lihaoyi]

sorry, haven't had time to look at this properly. I'm hoping that when @alexarchambault releases coursier 1.0.0 I can switch to it and all my ivy problems will magically go away... I don't actually know how ivy works

[hohonuuli]

Just a note that I'm having the same issue. Using @ didn't fix it for me either. (Also, ammonite is fantastic BTW)

[drdozer]

Is there a fix for this? I have a dependency on the postgres jdbc jar, in https://maven.atlassian.com/3rdparty/ and while i can load this in the REPL, I can't work out how to add the resolver in a script to get it to work.

[drdozer]

A work-around is to manually load that dependency into your local maven cache:

mvn dependency:get -DrepoUrl=https://maven.atlassian.com/3rdparty/ -DgroupId=postgresql -DartifactId=postgresql -Dversion=9.4.1208-jdbc42-atlassian-hosted

[lihaoyi]

Should be fixed in daa4768

[dportabella]

cool! i see the fix is committed in the "test" branch.
is it possible to get a notification when the fix is released?

[lihaoyi]

Come hang out in the gitter channel or follow me on twitter and you'll get pinged =)

[lihaoyi]

At some point, the Ammonite REPL will start pinging you about updated versions (#488) but that's for the future

[dportabella]

ok, thx!

[lihaoyi]

http://www.lihaoyi.com/Ammonite/#0.9.0 is out

[dportabella]

Cool! I confirm it works!
and so that this Web2Warc script!
