问题
I try to compile/build scala project with sbt, there are two plugins mentioned in project/plugins.sbt:
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.6.17")
addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.3.4")
Error while importing sbt project:
[error] sbt.librarymanagement.ResolveException: download failed:
com.typesafe.play#sbt-plugin;2.6.17!sbt-plugin.jar
[error] download failed: com.typesafe.sbt#sbt-native-packager;1.3.4!sbt-native-
packager.jar
Seems that problem in certificates for repositories, so i manually take each certificate and add it to my keystore with a command (i use ubuntu):
keytool -import -alias "artifact server2" -keystore /usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts -file _.bintray.com
But it doesn't help.
Update: i solved my problem by manual adding all certificates (end and intermediate) from repo's hosts to local keystore.

This issue had me almost ready to throw my macbook out the window.
On my mac, the java cacerts is located here:
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/lib/security/cacerts
To get ahold of the required certificate for sbt-native-packager I used this (which I stole from someone, and now I can't find the attribution):
echo -n | openssl s_client -connect repo.scala-sbt.org:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/scala-sbt.cert
Then to add it to the java trust store, I used Stanislav's solution above:
sudo keytool -import -alias "scala-sbt server" -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/lib/security/cacerts -file /tmp/scala-sbt.cert
Remember that the default password for the cacerts file is changeit
And then the next time I ran sbt the plugin downloaded and I almost wept tears of joy.
