是否有Maven的“仅编译器"?依赖工件的范围 [英] Is there a Maven "compiler-only" scope for dependency artifacts

问题描述

我意识到这更多是语义上的追求，而不是功能上的追求.

I realise this is more of a semantic quest rather than a functionality quest.

我有三种类型的编译范围依赖项:

I have three types of compile-scope dependencies:

1. 仅编译范围，在运行时不使用. GWT客户端开发人员，MVP4G，RestyGWT，源保留注释处理器.我使用REST，因此不需要GWT服务器端.

1. Compile-only scope, not used at run-time. GWT client-side dev, MVP4G, RestyGWT, Source retention annotation processors. I use REST, so I don't need GWT server side.

提供-编译需要Hibernate jar，但由JBoss提供.

Provided - Hibernate jars required for compilation but provided by JBoss.

编译+运行时jars.

Compile + runtime jars.

对于情况2，我们可以使用提供的范围.情况3，我们将使用编译范围.

For case 2, we could use provided scope. Case 3, we would use compile scope.

但是对于情况1，即使JBoss根本不提供这些文件，我也使用提供的范围.在运行时也不需要它们.

However for case 1, I use provided scope, even though JBoss does not provide those files at all. Nor are they needed at run-time.

无论如何，您是否认为Maven应该为除了编译时才真正不需要伪像的范围提供提供"的同义词?也许，应该有一个仅编译"作用域吗?

Anyway, don't you think Maven should provide for a synonym for "provided" for a scope where the artefacts are not really needed except at compile time? Perhaps, should there be a "compile-only" scope?

推荐答案

如果jars不是真正的运行时"依赖项(仅用于构建)，而不是最终工件，则可以通过多种方式将它们排除:

If the jars with are not true "runtime" dependencies (only for building) but not for the final artifact, you can exclude them various means:

1. 排除在程序集描述符中
2. 排除在jar(或战争，耳朵，任何东西)插件配置中
3. Shade Plugin最小化罐子目标

1. Exclusion in the assembly descriptor
2. Exclusion in the jar (or war, ear, whatever) plugin configuration
3. Shade Plugin minimize jar goal

我同意交付不必要的类很烦人(我已经在生产部署中看到过junit和testng jars-brrrr ...)，但是从所有实际目的来看，这只是一个很小的问题.

I agree that shipping unnecessary classes is annoying (I've seen junit and testng jars in production deployments - brrrr...), but for all practical purposes it's a rather minor one.

如果您遇到依赖冲突(即提供库或框架的所有deps"版本)，那就是另一回事了，但听起来并不像您在这里面临的那样.

If you have a dependency conflict (i.e shipping a "all deps" version of a library or framework), that's a different story, but doesn't sound like what you're facing here.
