### sbt-cross-building
|
||
|
|
|
||
|
|
[@jrudolph][@jrudolph]'s sbt-cross-building is a plugin author's plugin.
|
||
|
|
It adds cross command `^` and sbtVersion switch command `^^`, similar to `+` and `++`,
|
||
|
|
but for switching between multiple sbt versions across major versions.
|
||
|
|
sbt 0.13.16 merges these commands into sbt because the feature it provides is useful as we migrate plugins to sbt 1.0.
|
||
|
|
|
||
|
|
To switch the `sbtVersion in pluginCrossBuild` from the shell use:
|
||
|
|
|
||
|
|
```
|
||
|
|
^^ 1.0.0-M5
|
||
|
|
```
|
||
|
|
|
||
|
|
Your plugin will now build with sbt 1.0.0-M5 (and its Scala version 2.12.2).
|
||
|
|
|
||
|
|
If you need to make changes specific to a sbt version, you can now include them into `src/main/scala-sbt-0.13`,
|
||
|
|
and `src/main/scala-sbt-1.0.0-M5`, where the binary sbt version number is used as postfix.
|
||
|
|
|
||
|
|
To run a command across multiple sbt versions, set:
|
||
|
|
|
||
|
|
```scala
|
||
|
|
crossSbtVersions := Vector("0.13.15", "1.0.0-M5")
|
||
|
|
```
|
||
|
|
|
||
|
|
Then, run:
|
||
|
|
|
||
|
|
```
|
||
|
|
^ compile
|
||
|
|
```
