How do I publish an Ivy Dependency via SBT? - scala

I am trying to use SFTP to publish a dependency to another server:
publishTo := Some(
Resolver.sftp(name, host, "/home/user/.ivy2/local")(Resolver.ivyStylePatterns)
)
This works as expected and it publishes to the remote server, but it doesn't create a "ivys" directory, only a "poms" directory. This leads Coursier (what I'm using on that machine to resolve dependencies) to be unable to resolve the dependency because it can't find "ivys/ivy.xml".
Any assistance would be greatly appreciated.

To publish Ivy style, as opposed to Maven, you should enable the following setting in your build:
publishMavenStyle := false
Resolver.ivyStylePatterns doesn't govern the publishing style (which artifacts to generate, etc.) It only specifies the repository paths structure, which are different between Ivy and Maven.

Sbt to publish to both Sonatype and Bintray

I have a scala library that I just converted from gradle to sbt.
By default it works by publishing to Sonatype upon release. However I also want to publish it to Bintray. The problem is that Bintray sbt plugin is overwriting the original publish to Sonatype.
I know I can sync to Sonatype and Maven central repository via Bintray. However I still like the way Sonatype handle the validation and check before I really can release it to Maven central.
How do I publish to both Sonatype and Bintray from my release server (not relying on Bintray to sync for me)?
I ran into the same problem and found a setup that works.
sbt-bintray supports a JVM property flag sbt.sbtbintray, When it is set to false, sbt-bintray will not overwrite the publishTo setting (and a few others). So to publish to both sonatype, just run the sbt publish once with the flag set to true and once to false.
However, I also use the sbt-ci-release plugin, which also overrides the publishTo setting (after bintray), but does not offer a flag to disable this. To workaround this, copy what sbt-bintray does into your own build:
publishTo := {
val old = publishTo.value
val p = (publishTo in bintray).value
if (BintrayPlugin.isEnabledViaProp) p
else old
}

Why does sbt keep downloading my snapshot dependencies?

I have an SBT project that depends on two snapshot dependencies. Every time I build it, it goes off to the remote repository to fetch the dependencies. This is true even if I set offline := true.
When I look at how it is trying to resolve the local dependencies, the build is saying it is looking in "local", i.e., ~/.ivy2/local/... -- which is a nonexistent directory.
The jars are in ~/.ivy2/cache/... and this is where SBT downloads them when it pulls the dependencies from the remote server.
I have searched my .sbt and .scala build files and the string "local" does not appear in them in connection with a repository or cache.
SBT is at version 0.13.11 building against scala 2.11.8.
Why is SBT doing this, and how can I get it to see the cached jars?
If you want to prevent SBT from trying to download from official repositories you could simply create a file project/offline-repositories:
[repositories]
mirror-central: file:////nexus/central
mirror-maven-central-org: file:////nexus/maven-central-org
...
(/nexus/central and /nexus/maven-central-org should contain a (partial) mirror of what you need offline)
Then call sbt with the sbt.repository.config property configured:
-Dsbt.override.build.repos=true \
-Dsbt.repository.config=./project/offline-repositories
For Reference:
http://www.scala-sbt.org/0.13/docs/Proxy-Repositories.html
How to prevent SBT from trying to download from official repositories?
EDIT
If you want to use your ~/.m2 cache:
[repositories]
mirror-central: file:////home/XXXXX/.m2/repository
mirror-maven-central-org: file:////home/XXXXX/.m2/repository
...
This apparently is because in my Ivy cache I had a file named ~/.ivy2/cache/com.xxx/xxx-utils/ivy-2.3.2-SNAPSHOT.xml.original , which the build was trying and failing to parse. I'm not sure where this file came from; conceivably it was put there manually ages ago.

How to create standalone jar file for elastic4s from sources?

I'm trying to create a standalone jar file from the elastic4s sources on github. I've used sbt compile as detailed on the github page, but I can't find the jar file.
How do I use sbt to create the jar file so I can import it into my projects as a dependency?
The compile task will only compile the project.
> help compile
Compiles sources.
If you want to create a jar file and use it as a dependency in your project, you have two ways of doing that.
Unmanaged dependency (not recommended)
Unmanaged dependency run +package, which will create a jar file for each supported scala version, which you can use in your projects as an unmanaged dependency. Copy the package-generated jar to lib folder in your project.
The jar files will be located in target/scala-2.11 and target/scala-2.10, depending on the Scala version you want to use it with.
Publish to Local Repository (recommended yet imperfect)
If you want to include your custom-built elastic4s, as a managed dependency, you have to run +publishLocal. This will do the same as above, but additionally it will publish the artifact to your local repository. Assuming you've built it with version := "1.2.1.1-SNAPSHOT", you can include it in your project by just adding:
libraryDependencies += "com.sksamuel.elastic4s" %% "elastic4s" % "1.2.1.1-SNAPSHOT"
What makes the approach imperfect is that once you shared the project on GitHub (or any other project sharing platform), people will have to do publishLocal themselves to be able to build your project. The dependency should therefore go to one of the official binary repositories so when a dependency is needed, it's downloaded from Internet. Consult Publishing.
What is the + character in front of the commands
The + in the commands is for cross-building, if you don't use it the command will be executed only using scalaVersion declared in the build.sbt of the project.

Scala Play / SBT Change Order of Resolvers

Is there a way to change the order Resolvers are chosen during build time. My goal is to have the typesafe repo attempted last, after local, and internal repo is tried and not found.
My *.boot.properties in my play (you see that I replaced 'typesafe' with my local):
[repositories]
local
maven-local
play-local: file:///C:/path/to/my/play/repository/locl/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext]
typesafe-ivy-releases: https://locl/repo/address/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext]
maven-central
However, during my build, the typesafe repo is still loaded
[debug] URLRepository(typesafe-ivy-releases,Patterns(ivyPatterns=List(http://repo.typesafe.com/typesafe/ivy-releases/[organisation]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]), artifactPatterns=List(http://repo.typesafe.com/typesafe/ivy-releases/[organisation]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]), isMavenCompatible=false))
Any ideas on how to make the typesafe repo go after other resolvers?
As I understand you want to use local repository as more as possible.
You don't need an order of repositories. Just use SBT key setting:
val offline = true
Here is an explanation of it from SBT documentation:
val offline = SettingKey[Boolean]("offline", "Configures sbt to work without a network connection where possible.", ASetting)

how do I get sbt to use a local maven proxy repository (Nexus)?

I've got an sbt (Scala) project that currently pulls artifacts from the web. We'd like to move towards a corporate-standardized Nexus repository that would cache artifacts. From the Nexus documentation, I understand how to do that for Maven projects. But sbt obviously uses a different approach. (I understand Ivy is involved somehow, but I've never used it and don't understand how it works.)
How do I tell sbt and/or the underlying Ivy to use the corporate Nexus repository system for all dependencies? I'd like the answer to use some sort of project-level configuration file, so that new clones of our source repository will automatically use the proxy. (I.e., mucking about with per-user config files in a dot-directory is not viable.)
Thanks!
Step 1: Follow the instructions at Detailed Topics: Proxy Repositories, which I have summarised and added to below:
(If you are using Artifactory, you can skip this step.) Create an entirely separate Maven proxy repository (or group) on your corporate Maven repository, to proxy ivy-style repositories such as these two important ones:
http://repo.typesafe.com/typesafe/ivy-releases/
http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/
This is needed because some repository managers cannot handle Ivy-style and Maven-style repositories being mixed together.
Create a file repositories, listing both your main corporate repository and any extra one that you created in step 1, in the format shown below:
[repositories]
my-maven-proxy-releases: http://repo.example.com/maven-releases/
my-ivy-proxy-releases: http://repo.example.com/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
Either save that file in the .sbt directory inside your home directory, or specify it on the sbt command line:
sbt -Dsbt.repository.config=<path-to-your-repo-file>
Good news for those using older versions of sbt: Even though, in the sbt 0.12.0 launcher jar at least, the boot properties files for older sbt versions don't contain the required line (the one that mentions repository.config), it will still work for those versions of sbt if you edit those files to add the required line, and repackage them into the sbt 0.12.0 launcher jar! This is because the feature is implemented in the launcher, not in sbt itself. And the sbt 0.12.0 launcher is claimed to be able to launch all versions of sbt, right back to 0.7!
Step 2: To make sure external repositories are not being used, remove the default repositories from your resolvers. This can be done in one of two ways:
Add the command line option -Dsbt.override.build.repos=true mentioned on the Detailed Topics page above. This will cause the repositories you specified in the file to override any repositories specified in any of your sbt files. This might only work in sbt 0.12 and above, though - I haven't tried it yet.
Use fullResolvers := Seq( resolver(s) for your corporate maven repositories ) in your build files, instead of resolvers ++= or resolvers := or whatever you used to use.
OK, with some help from Mark Harrah on the sbt mailing list, I have an answer that works.
My build class now looks like the following (plus some other repos):
import sbt._
//By extending DefaultWebProject, we get Jetty support
class OurApplication(info: ProjectInfo) extends DefaultWebProject(info) {
// This skips adding the default repositories and only uses the ones you added
// explicitly. --Mark Harrah
override def repositories = Set("OurNexus" at "http://our.nexus.server:9001/nexus/content/groups/public/")
override def ivyRepositories = Seq(Resolver.defaultLocal(None)) ++ repositories
/* Squeryl */
val squeryl = "org.squeryl" % "squeryl_2.8.0.RC3" % "0.9.4beta5"
/* DATE4J */
val date4j = "hirondelle.date4j" % "date4j" % "1.0" from "http://www.date4j.net/date4j.jar"
// etc
}
Now, if I delete the Squeryl tree from my machine's .ivy2/cache directory, sbt tries to grab it from the Nexus tree with the appropriate URL. Problem solved!
All you need is to define a property file sbt.boot.properties which will allow you to:
redefine the ivy cache location (I need that because it would be otherwise part of our roaming Windows profile, which is severely limited in disk space in our shop. See Issue 74)
define any other Maven repo you want

[ivy]
cache-directory: C:\HOMEWARE\projects\.ivy2\cache
Note: this sbt.boot.properties file is inspired from:
the one mentioned in the "Generalized Launcher" page of the sbt project.
the one found within sbt-0.74 itself!
I have commented any external Maven repository definition, and added a reference to my own Nexus Maven repo.
The launcher may be configured in one of the following ways in increasing order of precedence:
Replace the /sbt/sbt.boot.properties file in the jar.
Put a configuration file named sbt.boot.properties on the classpath. Put it in the classpath root without the /sbt prefix.
Specify the location of an alternate configuration on the command line. This can be done by:
either specifying the location as the system property sbt.boot.properties
or as the first argument to the launcher prefixed by '#'.
The system property has lower precedence.
Resolution of a relative path is:
first attempted against the current working directory,
then against the user's home directory,
and then against the directory containing the launcher jar.
An error is generated if none of these attempts succeed.
Define a sbt.bat wrapper (in order to be sure to specify your sbt.boot.properties) like:
C:\HOMEWARE>more C:\HOMEWARE\bin\sbt.BAT
#echo off
set t=%~dp0
set adp0=%t:C:\="%"
set SBT_DIR=%adp0%..\apps\sbt-0.74
dir C:\%SBT_DIR%\sbt-launch-0.7.4.jar
# if needed, add your proxy settings
set PROXY_OPTIONS=-Dhttp.proxyHost=my.proxy -Dhttp.proxyPort=80xx -Dhttp.proxyUser=auser -Dhttp.proxyPassword=yyyy
set JAVA_OPTIONS=-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256m -Xmx512M -cp C:\HOMEWARE\apps\sbt-0.74\sbt-launch-0.7.4
set SBT_BOOT_PROPERTIES=-Dsbt.boot.properties="sbt.boot.properties"
cmd /C C:\HOMEWARE\apps\jdk4eclipse\bin\java.exe %PROXY_OPTIONS% %JAVA_OPTIONS% %SBT_BOOT_PROPERTIES% -jar C:\HOMEWARE\apps\sbt-0.74\sbt-launch-0.7.4.jar %*
And your sbt will download artifacts only from:
your Nexus
your local Maven repo.
Just tested at home with an old Nexus opensource 1.6 I had running, java 1.6, sbt07.4
C:\Prog\Java\jdk1.6.0_18\jre\bin\java -Xmx512M -Dsbt.boot.properties=sbt.boot.properties - jar "c:\Prog\Scala\sbt\sbt-launch-0.7.4.jar"
That gives:
[success] Build completed successfully.

If I put 2.7.7 (while still having all repo commented), yes, it won't generate an error:

But that's only because it already had downloaded scala2.8.0 during my previous tries.
If I remove that library from my project/boot directory, then it will throw an Exception:

Well this has bugged me for a while so I found a guy that has written an SBT plugin for maven out on github called maven-sbt so all you have to do is include it in your plugins project and make your project mixin with maven.MavenDependencies and all your operations like update and publish-local work with your local maven. The nice thing about that is if you are like me, your org is all maven. So, all you libs are in you local maven repo but if for some reason you build with sbt first, then you start getting a bunch or jars in ivy too. What a waste of space, and time since you will still need to get them for your maven builds.
That said, I wish this were built into sbt so I would not need to add it to every project. Maybe as a processor at least. He mentioned in one thing I read that he would like to add it to 0.9 but I have not been able to find it.
I got this error because I had a blank file in ~/.sbt/repositories. Both adding repositories to the file and removing the file solved the problem.
