執行sbt任務命令時看不到jacoco任務（-v也試過）

Question

我試圖用jacoco將測試報告集成到我的sbt項目中。 https://github.com/sbt/jacoco4sbt

我加jacoco.settings到build.sbt

我還添加了addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.6")到plugins.sbt

當我運行sbt jacoco:check，它工作正常。但是，當我試圖查看jacoco有多少任務時，sbt tasks未顯示與jacoco相關的任何內容。

我必須去源代碼來看看它。

https://github.com/sbt/jacoco4sbt/blob/master/src/main/scala/de/johoop/jacoco4sbt/Keys.scala

我可以知道爲什麼沒有顯示爲sbt tasks命令jacoco，什麼是看的插件

編輯所有可用的任務最好的方法：

我懷疑聲明lazy val Config = config("jacoco") extend(Test) hide意味着jacoco擴展了Test任務，所以它不會在sbt任務中顯示它，但我不確定。

Answer 1

通過運行

> tasks -v 

編輯：如果不工作考慮增加更多的「v」可以，如tasks -vvv，甚至tasks -V看到所有的任務。

我明白了，例如，cover：

This is a list of tasks defined for the current project. 
It does not list the scopes the tasks are defined in; use the 'inspect' command for that. 
Tasks produce values. Use the 'show' command to run the task and print the resulting value. 

    check     Executes the tests and saves the execution data in 'jacoco.exec'. 
    classesToCover   compiled classes (filtered by includes and excludes) that will be covered 
    clean     Cleaning JaCoCo's output-directory. 
    compile    Compiles sources. 
    console    Starts the Scala interpreter with the project classes on the classpath. 
    consoleProject   Starts the Scala interpreter with the sbt and the build definition on the classpath and useful imports. 
    consoleQuick   Starts the Scala interpreter with the project dependencies on the classpath. 
    copyResources   Copies resources to the output directory. 
    cover     Executes the tests and creates a JaCoCo coverage report. 
    coveredSources   Covered Sources. 

還要注意說話是算數的開頭（包裝爲清楚起見）：

It does not list the scopes the tasks are defined in; 
    use the 'inspect' command for that. 

導致

> inspect cover 
[info] No entry for key. 
[info] Description: 
[info] Executes the tests and creates a JaCoCo coverage report. 
[info] Delegates: 
[info] *:cover 
[info] {.}/*:cover 
[info] */*:cover 
[info] Related: 
[info] jacoco:cover 

所以你知道運行jacoco:cover
