如何在IVY中复制没有提供库的运行时库 [英] How to copy runtime libraries without the provided ones in IVY

问题描述

我以为我不需要问这个，但是我没有任何进展.

I thought I wouldn't need to ask this but I am not having any progress.

此问题的解决方案: ivy如何将maven范围映射到ivy配置实际上是在理论部分解决问题.

The solution to this question: How are maven scopes mapped to ivy configurations by ivy actually addresses question but in its theoretical part.

我有此配置:

<conf name="compile"  description="???" />
<conf name="runtime"  description="???" extends="compile" />
<conf name="test"     description="???" extends="runtime" />
<conf name="provided" description="???" />

假设我具有这种依赖性:

Assume I have this dependency:

<dependency org="org.apache.tomcat" name="servlet-api" rev="6.0.16" transitive="false" />

我想要的是:当我将ivy:retrieve绑定到.war lib目录之前将其复制到库中时，我只想复制所有运行时(并隐式编译)，而没有servlet-api.

What I want is: when I invoke the ivy:retrieve to copy the libraries to the .war lib directory before bundling it, I want only to copy all runtime (and compile implicitly) but no servlet-api.

那么如何使用ivy:retrieve呢?

so how to use ivy:retrieve then?

<ivy:retrieve conf="WHAT_TO_PUT_HERE" />

以及如何配置依赖项:

<dependency conf="WHAT_IS_THE_CONF_MAPPING" org="org.apache.tomcat" name="servlet-api" rev="6.0.16" transitive="false" />

我在这里高原，因此，请提供任何帮助.

I'm plateauing here, so please any help would be appreciated.

知道servlet-api的ivy.xml定义了工件

Knowing that the ivy.xml for servlet-api defines the artifact with

conf="master"

所以我认为问题是如何真正"映射所提供的maven范围到所提供的IVY配置.

So I think the question is how to 'really' map Provided scope of maven to the provided configuration of IVY.

推荐答案

这是将依赖项映射到本地提供"配置的方式:

This is how you map a dependency onto the local "provided" configuration:

<dependency org="org.apache.tomcat" name="servlet-api" rev="6.0.16" conf="provided->master"/>

配置映射如下:

provided->master
   ^        ^
   |        |
 Local    Remote
 config   config

如答案中所述，特殊的主"配置仅包含此模块本身发布的工件，没有传递依赖项:

As explained in the answer the special "master" configuration contains only the artifact published by this module itself, with no transitive dependencies:

这意味着不需要"transitive = false"属性.

This means the "transitive=false" attribute is not required.

如何使用配置由您决定.第一种方法比较简单，但是我更喜欢第二种方法，因为我的配置报告与我的类路径内容匹配

How you use the configuration is up to you. The first option is simpler, but I prefer the second approach because my configuration reports match my classpath contents

您可以创建一个单一的类路径，如下所示:

You can create a single classpath as follows:

<ivy:cachepath pathid="compile.path" conf="compile,provided"/>

然后可以在javac任务中使用它，如下所示:

This can then be used in the javac task as follows:

<javac ... classpathref="compile.path">
..

选项2

或者我更喜欢在配置和类路径之间建立一二一映射:

Option 2

Or I prefer to have a one-2-one mapping between configurations and classpaths:

<ivy:cachepath pathid="compile.path" conf="compile"/>
<ivy:cachepath pathid="provide.path" conf="provided"/>

后一种方法的问题在于，javac任务需要具有如下明确声明的类路径用法:

The problem with the latter approach is that the javac task need to have the classpath usage explicitly stated as follows:

<javac ...
   <classpath>
      <path refid="compile.path"/>
      <path refid="provided.path"/>
   </classpath>

我认为这清楚地解释了您如何使用此特殊提供的范围，但这确实取决于您.

I think this explicitly explains how you use this special provided scope, but it's really up to you.
