Is it possible to use gradle to develop scala projects?
提问by Freewind
I'm using sbt to build scala projects, but it always seems too complex(unfamiliar) and heavy to me. I'm also using gradle to build java projects, and which makes me happy.
我正在使用 sbt 来构建 Scala 项目，但它对我来说似乎总是太复杂（不熟悉）和沉重。我也在使用 gradle 来构建 java 项目，这让我很高兴。
I wonder is it possible to use gradle to build scala projects? Is there any big scala projects that uses gradle?
我想知道是否可以使用 gradle 来构建 Scala 项目？有没有使用 gradle 的大型 Scala 项目？
Some of my friends just tell me "Never ever think of using gradle for scala project", but refused to tell me the reason.
有些朋友只是告诉我“从来没有想过在Scala项目中使用gradle”，但拒绝告诉我原因。

It's quite easy to use gradlewith Scala. We did it for a long time (team mixed of Java ,Groovy and Scala developers) and have been quite happy with it. Most things work quite well out of the box.
在 Scala 中使用gradle非常容易。我们做了很长时间（由 Java、Groovy 和 Scala 开发人员组成的团队）并且对它非常满意。大多数东西开箱即用。

There are some problems/downfalls though:
但是有一些问题/缺点：
- Mixed code compilation when depending on Scala Code from Java in Mixed Code projects. (Some configuration and it will work, but not out of the box)
- more configuration for Scala specific tools needed as in sbt
- Integration of some Scala-Tools like the Scalastyleor scctis not possible yet
- no sbt console(gradle console has not been working properly since the last time I checked)
- adding the scala_version number to artifacts has to be added manually each time (no %%as in sbt)
- 在混合代码项目中依赖于 Java 中的 Scala 代码时的混合代码编译。（一些配置，它会工作，但不是开箱即用的）
- sbt 中所需的 Scala 特定工具的更多配置
- 集成一些 Scala 工具，如Scalastyle或scct尚不可能
- 没有sbt 控制台（自从我上次检查以来，gradle 控制台一直没有正常工作）
- 每次都必须手动添加 scala_version 编号到工件（没有%%就像在 sbt 中一样）

It's definitely possible. Gradle's Scala support is documented in the "Scala plugin" chapter in the Gradle User Guide. The plugin is used by big companies on big projects, and can be configured to use the same incremental Scala compiler as sbt. So best try for yourself and see if it fits your requirements.
绝对有可能。Gradle 的 Scala 支持记录在Gradle 用户指南的“Scala 插件”一章中。该插件被大公司用于大项目，并且可以配置为使用与 sbt 相同的增量 Scala 编译器。所以最好自己尝试一下，看看它是否符合您的要求。
