This is an sbt plugin, which helps to resolve dependencies from and publish to Amazon S3 buckets (private or public).
This plugin can publish artifacts in maven or ivy style, but it can resolve only ivy artifacts:
Ivy artifacts | publish | resolve | Maven artifacts | publish | resolve | |
---|---|---|---|---|---|---|
public | ✓ | ✓ | public | ✓ | * | |
private | ✓ | ✓ | private | ✓ | ✗ |
In project/plugins.sbt
:
resolvers += "Era7 maven releases" at "https://s3-eu-west-1.amazonaws.com/releases.era7.com"
addSbtPlugin("ohnosequences" % "sbt-s3-resolver" % "<version>")
(see the latest version in the releases list)
Note that since
v0.11.0
this plugin is compiled and published only for scala-2.10/sbt-0.13 or higher. If you want it for sbt-0.12, use versionv0.10.1
.
Key | Type | Default |
---|---|---|
awsProfile |
String |
"default" |
s3credentials |
AWSCredentialsProvider |
see below |
s3region |
Region |
EU_Ireland |
s3overwrite |
Boolean |
same as isSnapshot key |
s3acl |
S3ACL |
PublicRead |
s3resolver |
(String, s3) => S3Resolver |
is set using all above |
Where
type Region = com.amazonaws.services.s3.model.Region
type AWSCredentialsProvider = com.amazonaws.auth.AWSCredentialsProvider
type S3ACL = com.amazonaws.services.s3.model.CannedAccessControlList
These defaults are added to your project automatically. So you can just tune the settings keys in build.sbt
.
You can use s3resolver
setting key that takes a name and an S3 bucket url and returns S3Resolver
which is implicitly converted to sbt.Resolver
.
Normal practice is to use different (snapshots and releases) repositories depending on the version. For example, here is such publishing resolver with ivy-style patterns:
publishMavenStyle := false
publishTo := {
val prefix = if (isSnapshot.value) "snapshots" else "releases"
Some(s3resolver.value("My "+prefix+" S3 bucket", s3(prefix+".cool.bucket.com")) withIvyPatterns)
}
You can also switch repository for public and private artifacts — you just set the url of your bucket depending on something. Here s3
constructor takes the name of your S3 bucket (don't worry about s3://
prefix).
You can add a sequence of S3 resolvers just like this:
resolvers ++= Seq[Resolver](
s3resolver.value("Releases resolver", s3("releases.bucket.com")),
s3resolver.value("Snapshots resolver", s3("snapshots.bucket.com"))
)
Note, that you have to write Seq[Resolver]
explicitly, so that S3Resolver
s will be converted to sbt.Resolver
before appending.
If your maven artifacts are public, you can resolve them using usual sbt resolvers just transforming your s3://my.bucket.com
to
"My S3 bucket" at "https://s3-<region>.amazonaws.com/my.bucket.com"
i.e. without using this plugin. Or if you're using it anyway, you can write:
"My S3 bucket" at s3("my.bucket.com").toHttps(s3region.value)
s3credentials
key has the AWSCredentialsProvider
type from AWS Java SDK. Different kinds of providers look for credentials in different places, plus they can be chained by the |
("or") operator (added in this plugin for convenience).
The default credentials chain in this plugin is
awsProfile := "default"
s3credentials :=
new ProfileCredentialsProvider(awsProfile.value) |
new InstanceProfileCredentialsProvider()
new ProfileCredentialsProvider(...)
which loads credentials for an AWS profile config filenew EnvironmentVariableCredentialsProvider()
which loads credentials from the environment variablesnew InstanceProfileCredentialsProvider()
which loads credentials from the Amazon EC2 Instance Metadata Service
You can find other types of credentials providers in the AWS Java SDK docs
If you have different profiles in your ~/.aws/credentials
file, you can choose the one you need by setting
awsProfile := "bob"
Or if you need a completely different credentials providers chain, you can change it, for example, like this:
s3credentials :=
file(System.getProperty("user.home")) / ".sbt" / ".s3credentials" |
new EnvironmentVariableCredentialsProvider() |
new SystemPropertiesCredentialsProvider()
You can check which credentials are loaded with the showS3Credentials
task:
sbt showS3Credentials
You can set patterns using .withPatterns(...)
method of S3Resolver
. Default are maven-style patterns (just as in sbt), but you can change it with the convenience method .withIvyPatterns
.
