"Insecure HTTP request is unsupported" Error in Scala

Question

I am getting the following error when attempting to run sbt run to run my Scala code:

insecure HTTP request is unsupported 'http://repo.typesafe.com/typesafe/releases'; switch to HTTPS or opt-in as ("typesafe-releases" at "http://repo.typesafe.com/typesafe/releases").withAllowInsecureProtocol(true), or by using allowInsecureProtocol in repositories file

This is strange because it was working perfectly fine last week and I have changed nothing in the code. I have tried adding ("typesafe-releases" at "http://repo.typesafe.com/typesafe/releases").withAllowInsecureProtocol(true) in my build.sbt file and resolver file, installing Java11, deleting my project folder, and completely reclone my code from the repository but nothing is working. I am using Visual Studios but have also tried on IntelliJ and get the same error.

Any advice would be greatly appreciated, as I have changed nothing and now suddenly my code doesn't compile anymore. Further details:

sbt.version = 1.4.0

Scala code runner version 2.12.10

My current built.sbt (please note that I did not have the resolve part added before, when my code was working fine. It was added as an attempt to resolve the issue but did not work):

scalaVersion := "2.12.10"

name := "name"
organization := "org"
version := "1.0"

libraryDependencies ++= Seq(
"org.scala-lang.modules" %% "scala-parser-combinators" % "1.1.2",
"org.apache.spark" %% "spark-core" % "3.0.1",
"org.apache.spark" %% "spark-sql" % "3.0.1",
"org.reactivemongo" %% "reactivemongo-bson-api" % "0.20.11",
"org.mongodb.spark" %% "mongo-spark-connector" % "3.0.0",
"com.ibm.db2.jcc" % "db2jcc" % "db2jcc4"
)

resolvers += Resolver.typesafeRepo("releases")

EDIT: I've discovered that this error occurs regardless of project, and even occurs when I simply run sbt by itself.

Do you still have SSLHandshakeException after upgrading java? What versions of scala/sbt do you use? Some more information and error details would be helpful. — tentacle

@tentacle thanks for your comments. None of the listed things above made any difference, I still got the same error. Additional version details added to the above. The error occurs after: [info] loading project definition — David Boulton

@TomerShetah The issue is that I never needed the resolver part in the first place, and my code was compiling and running completely fine. I have tried and added the resolver resolver part is below anyway: resolvers += Resolver.typesafeRepo("releases") resolvers += Resolver.typesafeIvyRepo("releases") — David Boulton

@TomerShetah I tried, this doesn't work unfortunately. Update: I've discovered the error occurs regardless of which project I'm opening, and still occurs by simply entering the SBT environment with the "sbt" command — David Boulton

Did you try deleting ~/.sbt folder? I had a repositories file in this folder that had HTTP references to the typesafe repo and deleting this folder resolved those sbt HTTP errors.

rm ~/.sbt/repositories was enough in my case.

I deleted the target folder. I was running clean on builder but was not enough

For anyone else using an Intellij setup with this issue, see below

Environment:

Scala 2.12.7
Intellij Ultimate
JVM 11

The issue seems to be a clash between the Intellij IDE SBT plugin ( still on 1.3.2 ) and what seems to be a silent update of sbt.

Running sbt ( version 1.4.3 ) in a terminal instead of using the built in plugin fixed the issue.

As mentioned in repo.typesafe.com, you can add to your sbt:

Resolver.typesafeIvyRepo("releases")

or:

Resolver.typesafeRepo("releases")

Depends whether you are using Ivy or not.

The reason to this warning is the fact that you are using http and not https. From sbt 1.4.0 release notes:

HTTP resolvers require explicit opt-in using .withAllowInsecureProtocol(true)

This is the PR that added it.

OP has made it clear that there's explicit opt-out in the build.

Tomer Shetah Over a year ago

@tentacle, the error message clearly shows that "typesafe-releases" at "http://repo.typesafe.com/typesafe/releases" is part of build.sbt. This is the reason to the warning, and replacing it with Resolver.typesafeIvyRepo("releases") will solve it.

@TomerShetah Thanks for your input, however this did not solve the issue. Additionally I am now getting "Failed to connect with build server, no functionality will work. See logs for more details." after attempting to rebuild build.sbt

David Boulton Over a year ago

@TomerShetah thanks for your suggestions. Please see working solution above by SSam.

Guilherme Over a year ago

resolvers += ("Typesafe repository" at "repo.typesafe.com/typesafe/releases/") .withAllowInsecureProtocol(true)

Had to edit ~/.sbt/repositories to use https.
