将gradle/sbt/maven项目转换为pants构建系统

Question

我正在为一个项目(scala)使用，我需要使用一些第三方依赖项，这些依赖项可以作为gradle、sbt或maven导入。是否有一种标准的方法可以将gradle.build/头文件/build.sbt/plugin转换为gradle.build文件？

下面的pom (插件部分)就是一个例子，说明在某种程度上需要转换成裤子。

谢谢

我不相信有任何工具可以将现有的poms转换为Pants。我认为目前还没有类似于几乎任何Maven插件的Pants插件。

似乎最好的选择是为您无法生存的转换制作Pants插件，并将您的构建转换为您正在迁移到的构建工具的标准(遗憾的是)。

下面是一些关于创建新插件的文档：

tasks.html

将代码Avro转换为一些Java代码的示例插件(对于基于Java的代码转换来说似乎是最好的启动程序)：

https://github.com/pantsbuild/pants/tree/master/contrib/avro/src/python/pants/contrib/avro

或者，您可以使用jvm_prep_command并以更简单的方式运行所需的java进程：
