Question

编写第一个sbt 0.13的插件，并尝试遵循https://www.scala-sbt.org/0.13/docs/Testing-sbt-plugins.html。一切都按广告进行，直到进行到步骤5。它打印消息“正在运行... /简单”，并且永远不会从那里继续前进：

主要项目的构建工作：

build/sbt -Dplugin.version=0.14.8 clean update compile

但是当我尝试教程中的第5步（即运行scripted）时，没有错误消息，但也没有成功-它永远不会终止。

更新：在Windows 7 + Babun Cygwin上，我没有收到任何错误消息。在Linux上，即使我按照指示通过了sbt，sbt也抱怨plugin.version。

[info] java.lang.RuntimeException: The system property 'plugin.version' is not defined.
[info] Specify this property using the scriptedLaunchOpts -D.

我该如何解决？

Answer 1

修正/澄清/找到解决方法：

首先，让我们澄清一下，https://www.scala-sbt.org/0.13/docs/Testing-sbt-plugins.html中引用的assembly插件必须添加到simple项目中，而不是主项目中。

接下来，我放弃了通过命令行参数设置sbt-assembly版本号，而直接指定了它

sheep-metadata-plugin\metadata\src\sbt-test\sheep-metadata-plugin\simple\project\plugins.sbt
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.8")

最好知道是否有人按照教程中的说明弄清楚该示例如何工作。

测试sbt插件
