How to Travis + Sonatype + Codecov a multi-module SBT build
Helper
A short helper for gitignore.io:
$ which gi
gi () {
curl -fL https://www.gitignore.io/api/${(j:,:)@}
}
Essentials
.gitignore
$ gi scala,emacs,java,sbt > .gitignore
project/plugin.sbt
addSbtPlugin("com.geirsson" % "sbt-ci-release" % "1.2.1")
addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.5.1")
build.sbt
inThisBuild(List(
organization := "<ORGANIZATION>",
homepage := Some(url("https://github.com/<ORG>/<REPO>")),
licenses := List("Apache-2.0" -> url("http://www.apache.org/licenses/LICENSE-2.0")),
developers := List(
Developer(
"<ALIAS>",
"<NAME>",
"<EMAIL>",
url("<WEBSITE>")
)
)
))
Signing key
Generate
$ gpg --gen-key
Enter your name, email, passphrase
Output should be similar to
[...]
pub rsa2048 2018-08-24 [SC] [expires: 2020-08-24]
<KEY_ID>
[...]
Grab the KEY_ID and store it in a variable
$ export KEY_ID=<KEY_ID>
Submit to key server
Copy the output of this:
$ gpg --armor --export "${KEY_ID}"
Paste the public key into https://pgp.mit.edu/ and submit. Also, for quicker propagation, do the same on http://keyserver.ubuntu.com/
Export private key
$ gpg --armor --export-secret-keys "${KEY_ID}" | base64 -w0 > project/secret
Enter the passphrase used when generating the key. The key is now Base64-encoded in project/secret
Travis configuration
Initialize
$ travis init scala --scala 2.12.6 --jdk openjdk8 --before-install 'git fetch --tags'
# Make sure PASSPHRASE, SONATYPE_USER and SONATYPE_PASS are escaped properly (despite the quotation)!!!
# Getting these escaped correctly is literally the hardest part :D
$ travis encrypt 'PGP_PASSPHRASE=<PASSPHRASE>' --add
$ travis encrypt 'SONATYPE_USERNAME=<SONATYPE_USER>' --add
$ travis encrypt 'SONATYPE_PASSWORD=<SONATYPE_PASS>' --add
$ travis encrypt-file ./project/secret ./project/zecret --add
$ echo "project/secret" >> .gitignore
Fix the line break in the openssl command, it's probably broken... Also, add || true to the end of it, so Pull Request builds will work
Add actual build
Add this line to your modules (or common settings)
build.sbt
[...]
settings(crossScalaVersions := List("2.12.6", "2.11.12"))
[...]
