使用 Ivy 解析 XSD [英] Resolving XSD's using Ivy

问题描述

请原谅我重复发帖，但我很想得到这个答案.

Forgive the double post but I am keen on an answer to this.

我想就我所采取的方法提供一些建议.我正在使用 Ivy 进行依赖管理，并且可以毫无问题地下载和使用我所有的 jar 文件.我还想在 Ant 中运行 <schemavalidate> 任务，并想使用 Ivy 下载指定的 xsd 和 dtd，从而消除初始下载后对网络连接的需要，并且减少我的构建时间.我想我有一个解决方案但想运行它通过一些额外的眼睛进行健全性检查和可能的改进建议.以下是我的构建脚本的相关部分.第一次检索调用使用我的默认 ivysettings.xml，第二次调用使用专门用于检索 xsd 和 dtd 的设置文件.任何反馈将不胜感激.

I would like some advice as to the approach I am taking. I am using Ivy for dependency management and am able to download and use all my jar files no issues. I would like to also run the <schemavalidate> task in Ant and would like to use Ivy to download the xsd's and dtd's as specified, thereby eliminating the need for a network connection after the initial download and also reducing my build time. I think I have a solution but wanted to run it by some extra eyes for a sanity check and suggestions for possible improvements. Below is the relevant parts of my build scripts. The first call to retrieve uses my default ivysettings.xml and second call uses a settings file specific for retrieving xsd's and dtd's. Any feedback would be appreciated.

build.xml:

有趣的问题.缓存架构文件可启用离线验证.

Interesting problem. Caching the Schema files enables off-line validation.

正如汤姆所说，我认为只需要一次检索.(我的示例同时获取 jars 和 schema 文件)

As Tom stated I think only a single retrieve is needed. (My example fetches both jars and schema files)

<ivy:retrieve pattern="${lib.dir}/[conf]/[artifact]-[revision].[ext]"/>

我对 ivy 和设置文件进行了一些更改.

I've offered some changes to the ivy and settings files.

我使用了 ivy 额外属性协助生成 Spring Schema URL:

I've used ivy extra attributes to assist with the generation of the Spring Schema URLs:

<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">
    <info organisation="com.myspotontheweb.demo" module="spring"/>

    <configurations defaultconfmapping="compile->default">
        <conf name="compile" description="Compile dependencies"/>
        <conf name="schemas" description="XML schema files"/>
    </configurations>

    <dependencies>
        <!-- Compile depedencies -->
        <dependency org="org.springframework" name="spring-core" rev="3.0.6.RELEASE"/>

        <!-- Schema dependencies -->
        <dependency org="org.springframework" name="schemas" rev="3.0" conf="schemas->default">
            <artifact name="spring-beans"   e:framework="beans" type="xsd"/>
            <artifact name="spring-context" e:framework="context" type="xsd"/>
            <artifact name="spring-mvc"     e:framework="mvc"   type="xsd"/>
            <artifact name="spring-tool"    e:framework="tool"  type="xsd"/>
            <artifact name="spring-util"    e:framework="util"  type="xsd"/>
        </dependency>

        <dependency org="com.sun.java" name="schemas" rev="5" conf="schemas->default">
            <artifact name="javaee_5"    type="xsd"/>
            <artifact name="web-app_2_5" type="xsd"/>
            <artifact name="javaee_web_services_client_1_2" type="xsd"/>
            <artifact name="jsp_2_1"     type="xsd"/>
        </dependency>

        <dependency org="org.w3" name="schemas" rev="2001" conf="schemas->default">
            <artifact name="XMLSchema" type="xsd"/>
            <artifact name="xml"       type="xsd"/>
        </dependency>
    </dependencies>
</ivy-module>

ivysettings.xml

配置ivy默认使用Maven仓库.使用 modules 声明将特殊模式模块路由到你的 URL 解析器.

ivysettings.xml

Configure ivy to use Maven repositories by default. Use a modules declaration to route the special schema modules to your URL resolvers.

<ivysettings>
    <settings defaultResolver="maven-repos"/>
    <resolvers>
        <chain name="maven-repos">
            <ibiblio name="central" m2compatible="true"/>
            ..
            Other Maven repositories go here
            ..
        </chain>
        <url name="spring-schemas">
            <artifact pattern="http://www.springframework.org/schema/[framework]/[artifact].[ext]"/>
        </url>
        <url name="javaee-schemas">
            <artifact pattern="http://java.sun.com/xml/ns/javaee/[artifact].[ext]"/>
        </url>
        <url name="w3-schemas">
            <artifact pattern="http://www.w3.org/2001/[artifact].[ext]"/>
        </url>
    </resolvers>
    <modules>
        <module organisation="org.springframework" name="schemas" resolver="spring-schemas"/>
        <module organisation="com.sun.java" name="schemas" resolver="javaee-schemas"/>
        <module organisation="org.w3"       name="schemas" resolver="w3-schemas"/>
    </modules>
</ivysettings>
