Apache Ivy和配置 [英] Apache Ivy and configurations

问题描述

我正在使用Ivy来管理我的依赖项，在提供的jar上存在一些问题

I'm using Ivy to manage my dependencies, with some problems on provided jars

这是我的ivy.xml文件

This is my ivy.xml file

<configurations>
    <conf name="local" visibility="private" />
    <conf name="compile" description="used for building" />
    <conf name="test" extends="compile" description="used for testing" />
    <conf name="runtime" description="used for running" />
    <conf name="master" description="used for publishing" />
    <conf name="default" extends="master, runtime" />
</configurations>
<dependencies>
    <dependency org="xalan" name="xalan" rev="2.7.1"/>
    <dependency org="org.w3c.css" name="sac" rev="1.3"/>
    <dependency org="com.lowagie" name="itext" rev="2.0.8">
            <exclude org="bouncycastle"/>
    </dependency>
<!--Provided-->
<dependency org="javax.ejb" name="ejb-api" rev="3.0" conf="compile"/>
<dependency org="javax.jms" name="jms-api" rev="1.1-rev-1" conf="compile"/>
</dependencies>

Ejb和jms由容器提供

Ejb and jms are provided by the container

执行后我得到

---------------------------------------------------------------------
|                  |            modules            ||   artifacts   |
|       conf       | number| search|dwnlded|evicted|| number|dwnlded|
---------------------------------------------------------------------
|      compile     |   8   |   0   |   0   |   0   ||   6   |   0   |
|      default     |   6   |   0   |   0   |   0   ||   6   |   0   |
---------------------------------------------------------------------

所以Ivy很好地解决了依赖性，但是当我执行此操作时

So Ivy is getting fine the dependencies but when I execute this

<ivy:cachepath pathid="normal.classpath" />
<pathconvert property="expanded.normal.classpath" refid="normal.classpath"/>
<echo message="${expanded.normal.classpath}" file="normal.classpath.txt"/>

<ivy:cachepath conf="compile" pathid="compile.classpath" />
<pathconvert property="expanded.compile.classpath" refid="compile.classpath"/>
<echo message="${expanded.compile.classpath}" file="compile.classpath.txt"/>

两个类路径都相同。
有人知道为什么吗？

Both classpath are the same. Anyone knows why?

推荐答案

第一个 ivy：cachepath 没有定义conf，它可以解析所有配置，因此包含每个模块。

The first ivy:cachepath has no conf defined, to it resolve all configurations, so every module is included.

第二个 ivy：cachepath 仅请求conf编译。因此，声明为 conf = compile 的依赖项（ conf = compile-> compile 的同义词）显然包括在内。并且还包括没有任何 conf 属性的依赖项，因为默认的conf是 *-> * 。

The second ivy:cachepath is requesting only the conf compile. So the dependencies which are declared as conf="compile" (synonymous of conf="compile->compile") are obviously included. And the dependencies without any conf attribute are also included, because the default conf is *->*.
