如何在Play 2.3中發佈帶publish/publishLocal的webjar資源？

Question

Since Play Framework 2.3 assets are packaged into one jar archive file.我想將這個jar自動發佈到該項目中，即publish或publishLocal我也希望發佈資產jar。

如何實現這一目標？

Answer 1

inspect tree dist後我設法找到產生資產文件的任務playPackageAssets：

[play-publish-webjar] $ inspect playPackageAssets 
[info] Task: java.io.File 
[info] Description: 
[info] 
[info] Provided by: 
[info] {file:/Users/jacek/sandbox/play-publish-webjar/}root/*:playPackageAssets 
[info] Defined at: 
[info] (sbt.Defaults) Defaults.scala:641 
[info] Dependencies: 
[info] *:playPackageAssets::packageConfiguration 
[info] *:playPackageAssets::streams 
[info] Reverse dependencies: 
[info] *:scriptClasspath 
[info] universal:mappings 
[info] Delegates: 
[info] *:playPackageAssets 
[info] {.}/*:playPackageAssets 
[info] */*:playPackageAssets 

一個天真的解決辦法可能是附加 webjar如由playPackageAssets到publishLocal任務的假象所產生的資產。添加以下build.sbt（該類型是展示你的合作伙伴）：

import play.PlayImport.PlayKeys._ 

packagedArtifacts in publishLocal := { 
    val artifacts: Map[sbt.Artifact, java.io.File] = (packagedArtifacts in publishLocal).value 
    val assets: java.io.File = (playPackageAssets in Compile).value 
    artifacts + (Artifact(moduleName.value, "asset", "jar", "assets") -> assets) 
} 

重複它要表現出類似行爲的其他任務。

不過我很懷疑這是最好的解決方案。
