How to change default settings of sbt-thrift plugin in SBT?

问题

I am using sbt-thrift plugin 0.6 with SBT 0.12 and I need to change the resource directory, source directory, output directory and other settings in my build configuration.

It doesn't seem to work as mentioned in README.

Can someone tell me how to do this thing?

回答1:

SBT 0.13 + sbt-thrift 0.7

NOTE Below is the same configuration for SBT 0.12 and sbt-thrift 0.6

I use SBT 0.13.1 and hence had to use sbt-thrift 0.7 from http://bigtoast.github.io/repo/com/github/bigtoast/sbt-thrift_2.10_0.13/0.7/.

project/plugins.sbt

resolvers += "bigtoast-github" at "http://bigtoast.github.com/repo/"

addSbtPlugin("com.github.bigtoast" % "sbt-thrift" % "0.7")

build.sbt

import com.github.bigtoast.sbtthrift.ThriftPlugin

seq(ThriftPlugin.thriftSettings: _*)

With the above build configuration, you may want to look at https://github.com/bigtoast/sbt-thrift/blob/master/src/main/scala/ThriftPlugin.scala for possible tasks and settings (I have not checked whether README.md's fully correct).

There's source-directory setting to set "Source directory for thrift files. Defaults to src/main/thrift".

> thrift:source-directory
[info] C:\dev\sandbox\thrift\src\main\thrift

To change the value use the following:

ThriftPlugin.thriftSourceDir := sourceDirectory.value / "my-own-source-dir"

and reload so the setting changes (react) accordingly:

> thrift:source-directory
[info] C:\dev\sandbox\thrift\src\my-own-source-dir\main\thrift

Please note that all the settings and tasks belong to the thrift config.

SBT 0.12 + sbt-thrift 0.6

project/plugins.sbt

resolvers += "bigtoast-github" at "http://bigtoast.github.com/repo/"

addSbtPlugin("com.github.bigtoast" % "sbt-thrift" % "0.6")

Since OP asked about multi-project build configuration, below is the definition of two projects with one configured with a custom value for thriftSourceDir.

project/MyBuild.scala

import sbt._
import Keys._
import com.github.bigtoast.sbtthrift.ThriftPlugin._

object MyBuild extends Build {
  lazy val thriftS = Defaults.defaultSettings ++
    thriftSettings ++
    Seq(
      thriftSourceDir <<= sourceDirectory(_ / "my-own-source-dir")
    )

  lazy val thriftP = Project("thriftProject", 
    file("."),
    settings = thriftS
  )

  lazy val someP = Project("some-other-project",
    file("some-other-project")
  )
}

With the build configuration, sbt shell gives you the following:

> sbt-version
[info] 0.12.4
> projects
[info] In file:/Users/jacek/sandbox/so/thrift-0.12/
[info]     some-other-project
[info]   * thriftProject
> thrift:source-directory
[info] /Users/jacek/sandbox/so/thrift-0.12/src/my-own-source-dir/main/thrift
> thriftProject/thrift:source-directory
[info] /Users/jacek/sandbox/so/thrift-0.12/src/my-own-source-dir/main/thrift
> some-other-project/thrift:source-directory
[info] /Users/jacek/sandbox/so/thrift-0.12/some-other-project/src
