Hi all, I'm trying to make a secure java client for ES 5.0, but I'm met with the following error. Any ideas?
Here is my code
It's weird because it passes the type checker.

Please don't post pictures of text, they are difficult to read and some people may not be even able to see them.

Can you check what version of xpack you are pulling in? This looks like you have an old version of xpack with a 5.0 version of transport client.

Hi @rjernst, thanks for your reply.
Here is my `build.sbt` file:
```auto
resolvers += "elasticsearch-releases" at "https://maven.elasticsearch.org/releases"
libraryDependencies ++= Seq(
"com.amazonaws" % "aws-java-sdk" % "1.9.8",
"com.jcraft" % "jsch" % "0.1.53",
"org.elasticsearch.plugin" % "x-pack" % "5.0.0-alpha4",
"org.elasticsearch.client" % "transport" % "5.0.0-alpha5"
)
```
I'm unable to pull in `5.0.0-alpha5` of Xpack due to a build issue: [Can't get 5.0.0-alpha5 from Maven](https://discuss.elastic.co/t/cant-get-5-0-0-alpha5-from-maven/58726/2)

@robert-blankenship Sorry for the delayed response on this. Mixing version of the transport client and x-pack will definitely cause issues like you see. The packaging issue you linked to has been fixed in 5.0.0-beta1. In fact, there is now a prebuilt xpack transport client which you can have as a single dependency. Take a look at `org.elasticsearch.client:x-pack-transport:5.0.0-beta1`. Also, note that the location of the elastic hosted maven repository has changed to `https://artifacts.elastic.co/maven`.
