sbt 1.1.1 

Bug fixes 


autoStartServer setting 

sbt 1.1.1 adds a new global Boolean setting called autoStartServer, which is set to true by default. When set to true, sbt shell will automatically start sbt server. Otherwise, it will not start the server until startSever command is issued. This could be used to opt out of server for security reasons.

sbt 1.1.0 

This is a feature release for sbt 1.0.x series.

Features, fixes, changes with compatibility implications 




Unified slash syntax for sbt shell and build.sbt 

This adds unified slash syntax for both sbt shell and the build.sbt DSL. Instead of the current <project-id>/config:intask::key, this adds <project-id>/<config-ident>/intask/key where <config-ident> is the Scala identifier notation for the configurations like Compile and Test. (The old shell syntax will continue to function)

These examples work both from the shell and in build.sbt.

Global / cancelable
ThisBuild / scalaVersion
Test / test
root / Compile / compile / scalacOptions
Zero / Zero / name

The inspect command now outputs something that can be copy-pasted:

> inspect compile
[info] Task:
[info] Description:
[info]  Compiles sources.
[info] Provided by:
[info]  ProjectRef(uri("file:/xxx/helloworld/"),"root")/Compile/compile
[info] Defined at:
[info]  (sbt.Defaults) Defaults.scala:326
[info] Dependencies:
[info]  Compile/manipulateBytecode
[info]  Compile/incCompileSetup

sbt server 

sbt server feature was reworked to use Language Server Protocol 3.0 (LSP) as the wire protocol, a protocol created by Microsoft for Visual Studio Code.

To discover a running server, sbt 1.1.0 creates a port file at ./project/target/active.json relative to a build:


local: indicates a UNIX domain socket. Here’s how we can say hello to the server using nc. (^M can be sent Ctrl-V then Return):

$ nc -U /Users/foo/.sbt/1.0/server/0845deda85cb41abcdef/sock
Content-Length: 99^M
{ "jsonrpc": "2.0", "id": 1, "method": "initialize", "params": { "initializationOptions": { } } }^M

sbt server adds network access to sbt’s shell command so, in addition to accepting input from the terminal, server also to accepts input from the network. Here’s how we can call compile:

Content-Length: 93^M
{ "jsonrpc": "2.0", "id": 2, "method": "sbt/exec", "params": { "commandLine": "compile" } }^M

The running sbt session should now queue compile, and return back with compiler warnings and errors, if any:

Content-Length: 296
Content-Type: application/vscode-jsonrpc; charset=utf-8

{"jsonrpc":"2.0","method":"textDocument/publishDiagnostics","params":{"uri":"file:/Users/foo/work/hellotest/Hello.scala","diagnostics":[{"range":{"start":{"line":2,"character":26},"end":{"line":2,"character":27}},"severity":1,"source":"sbt","message":"object X is not a member of package foo"}]}}

VS Code extension 

The primary use case we have in mind for the sbt server is tooling integration such as editors and IDEs. As a proof of concept, we created a Visual Studio Code extension called Scala (sbt).

Currently this extension is able to:

Filtering scripted tests using project/ 

For all scripted tests in which project/ exist, the value of the sbt.version property is read. If its binary version is different from sbtBinaryVersion in pluginCrossBuild the test will be skipped and a message indicating this will be logged.

This allows you to define scripted tests that track the minimum supported sbt versions, e.g. 0.13.9 and 1.0.0-RC2. #3564/#3566 by @jonas
