如何从现有任务创建自定义任务

我想创建使用publishLocal in Docker,login in ecr和publishLocal in Docker的自定义任务。如何从现有任务创建自定义任务

另请注意，我仅在自定义任务中修改了“Docker中的publishLocal”设置。

我试着写代码下面，但它没有工作。

val releaseDev = taskKey[Unit]("push docker image") 
releaseDev := (push in ecr).value 
releaseDev := releaseDev.dependsOn(publishLocal in Docker).value 
releaseDev := (projectSettings ++ Seq(repositoryName in ecr := (packageName in Docker).value + "-stg" + ":" + (version in Docker).value))

以下是如何从您的自定义任务中触发现有任务的方法。从你的问题，你希望他们在一些特定的顺序被触发，所以这里是你需要做的

lazy val releaseDev = taskKey[Unit]("push docker image") 
releaseDev := Def.sequential(push in ecr, publishLocal in Docker).value

现在，当你触发releaseDev这将首先push in ecr然后publishLocal in Docker。

注：不要忘记添加lazy在taskKey定义，因为它可能会导致一些奇怪的初始化的问题。

谢谢你亲切的回答，并修复我可怜的英语。如何仅在'releaseDev'任务中修改设置。我想通过任务更改repositoryName。 –

'in releaseDev：= ...'？ – marios

谢谢marios。我试着写下面的代码，并正确处理任务依赖关系。但是，使用repositoryName作为项目设置之一。

// docker publish settings 
import com.amazonaws.regions.{Region, Regions} 

region in ecr := Region.getRegion(Regions.AP_NORTHEAST_1) 
repositoryName in ecr := (packageName in Docker).value + ":" + (version in Docker).value 
localDockerImage in ecr := (packageName in Docker).value + ":" + (version in Docker).value 

// Publisher Setting 
//~~~~~~~~~~~~~~~~~~~ 
import ReleaseTransformations._ 

releaseProcess := Seq[ReleaseStep](
    checkSnapshotDependencies, 
    inquireVersions, 
    runClean, 
    runTest, 
    setReleaseVersion, 
    commitReleaseVersion, 
    tagRelease, 
    ReleaseStep(state => Project.extract(state).runTask(publishLocal in Docker, state)._1), 
    ReleaseStep(state => Project.extract(state).runTask(login in ecr, state)._1), 
    ReleaseStep(state => Project.extract(state).runTask(push in ecr, state)._1), 
    setNextVersion, 
    commitNextVersion, 
    pushChanges 
) 

lazy val releaseDev = taskKey[Unit]("push docker image") 
releaseDev := Def.sequential(publishLocal in Docker, login in ecr, push in ecr).value 
(repositoryName in ecr) in releaseDev := (packageName in Docker).value + "-stg" + ":" + (version in Docker).value
