如何使用gradle复制所有源码罐 [英] how to copy all source jars using gradle

问题描述

我们有一个旧的playframework 1.2.x版本，我们将所有的jar复制到project / lib中，以便playframework可以使用它们。我们很乐意复制所有的源代码jar，所以当runnig玩eclipsify时，我们可以查看所有的第三方源代码。有没有办法用gradle来做到这一点？

我的意思是我在运行gradle eclipse时下载的所有源代码jar，因为我看到它们下载缓存位置。我们在一个项目中使用gradle eclipse为我们调用了eclipsify，所以我们可以100％使用gradle。

谢谢，
Dean

解决方案

这并不像预期那样简单。以下片段将Java项目的所有依赖项（运行时+编译）的源jar复制到特定文件夹中：

 任务copySourceJars （type：Copy）{
 def deps = configurations.runtime.incoming.dependencies.collect {dependency  - > 
 dependency.artifact {artifact  - > 
 artifact.name = dependency.name 
 artifact.type ='source'
 artifact.extension ='jar'
 artifact.classifier ='sources'
} $ （配置.detachedConfiguration（deps依赖[]）。resolvedConfiguration.lenientConfiguration.getFiles（Specs.SATISFIES_ALL））
（'sourceLibs'）
 
 
 
 b} 
  

这里我们使用lenientConfiguration的原因是，我们不想失败，如果源神器无法解析。可能有一种更优雅的方式，但我没有深入了解这一点。

希望它有帮助，

We have an old playframework 1.2.x version where we copy all the jars to project/lib so playframework can consume them. We would LOVE to copy all the source jars as well so that when runnig play eclipsify, we can view all the third party source. Is there a way to do this with gradle?

and I mean all the source jars that were downloaded when I ran gradle eclipse as I saw them download the cache locations. We have gradle eclipse calling play eclipsify for us on the one project as well so we can 100% just use gradle.

thanks, Dean

解决方案

this is not that straight forward as expected. The following snippet copies the source jars for all dependencies (runtime + compile) of a java project into a specific folder:

    task copySourceJars(type:Copy){
        def deps = configurations.runtime.incoming.dependencies.collect{ dependency ->
            dependency.artifact { artifact ->
                    artifact.name = dependency.name
                    artifact.type = 'source'
                    artifact.extension = 'jar'
                    artifact.classifier = 'sources'
                }
            dependency
        }
        from(configurations.detachedConfiguration(deps as Dependency[]).resolvedConfiguration.lenientConfiguration.getFiles(Specs.SATISFIES_ALL))
        into('sourceLibs')
    }

The reason we use a lenientConfiguration here is, that we don't want to fail if a source artifact cannot be resolved. There might be a more elegant way, but I havn't looked deeper into that.

hope it helps,
