测试sbt插件

Question

为SBT0.13编写了我的第一个插件，并试图遵循https://www.scala-sbt.org/0.13/docs/Testing-sbt-plugins.html。所有这些都像广告中所宣传的那样工作，直到第5步。它打印消息“运行./简单”，并且永远不会从那里继续：

主要工程的建造：

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

但是，当我尝试本教程中的步骤5(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，我没有收到错误消息。在Linux上，sbt抱怨plugin.version，尽管我按照指示传递了它。

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

我怎么才能解决这个问题？

Answer 1

固定/澄清/找到解决办法：

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

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

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

如果有人知道如何像本教程中所描述的那样使该示例工作，那将是很好的。
