如何使用不同的分类器下载Ivy中的多个Maven依赖项？

Question

我试图依赖Neo4j服务器jar和Neo4j服务器jar - 静态web.jar在常春藤.我正在尝试类似的东西

<ivy-module version="2.0" xmlns:m="http://ant.apache.org/ivy/maven">
<info organisation="org.jimwebber" module="neo4j-koans"/>
<dependencies>
    <dependency org="org.springframework.data" name="spring-data-neo4j" rev="1.0.0.RELEASE">
        <exclude module="jms"/>
        <exclude module="jmxtools"/>
        <exclude module="jmxri"/>
        <exclude org="org.slf4j" name="slf4j-log4j12"/>
    </dependency>
    <dependency org="org.aspectj" name="aspectjrt" rev="1.6.11.RELEASE"/>
    <dependency org="org.aspectj" name="aspectjtools" rev="1.6.11.RELEASE"/>
    <dependency org="org.neo4j.app" name="neo4j-server" rev="1.5-SNAPSHOT" m:classifier="static-web"/>
    <dependency org="org.neo4j.app" name="neo4j-server" rev="1.5-SNAPSHOT"/>
    <dependency org="org.neo4j" name="neo4j-community" rev="1.5-SNAPSHOT"/>
    <dependency org="org.neo4j" name="neo4j-shell" rev="1.5-SNAPSHOT"/>
    <dependency org="org.codehaus.jackson" name="jackson-core-asl" rev="1.7.5"/>
    <dependency org="org.codehaus.jackson" name="jackson-mapper-asl" rev="1.7.5"/>
    <dependency org="com.sun.jersey" name="jersey-client" rev="1.3"/>
    <dependency org="org.mockito" name="mockito-all" rev="1.8.5"/>
    <dependency org="junit" name="junit" rev="4.7"/>        
</dependencies>
</ivy-module>

但我从来没有得到"staic-web".jar,现在也出错了.谁知道怎么做？

谢谢你的任何提示!

这是您检索与Maven模块关联的多个工件的方法:

<dependency org="org.neo4j.app" name="neo4j-server" rev="1.5-SNAPSHOT">
    <artifact name="neo4j-server" type="jar" />
    <artifact name="neo4j-server" type="jar" m:classifier="static-web"/>
</dependency>

由于Maven使用分类器引用其他工件的方式,语法很奇怪.

需要将neo4j快照存储库添加到您的ivysettings.xml文件中(快照版本不会发布到Maven Central)

<ivysettings>
    <settings defaultResolver="chain"/>
    <resolvers>
        <chain name="chain">
            <ibiblio name="central" m2compatible="true"/>
            <ibiblio name="neo4j-snapshot" m2compatible="true" root="http://repo.neo4j.org/content/repositories/snapshots"/>
        </chain>
    </resolvers>
</ivysettings>

其他问题

版本更正

<dependency org="org.aspectj" name="aspectjrt" rev="1.6.11"/>
<dependency org="org.aspectj" name="aspectjtools" rev="1.6.11"/>

破坏的存储库POM

使用快照存储库的问题有时会破坏POM.Ivy无法处理以下文件:

http://repo.neo4j.org/content/repositories/snapshots/org/neo4j/app/neo4j-server/1.5-SNAPSHOT/neo4j-server-1.5-SNAPSHOT.pom

这可以防止常春藤下载neo4j-server arifacts ....

[ivy:retrieve] :::: WARNINGS

变通

在设置文件中,配置ivy以使用url解析器直接检索工件.该ibiblio上解析器被用于所有其它模块,其多金属氧酸盐是有效的.

<ivysettings>
    <settings defaultResolver="chain"/>
    <resolvers>
        <chain name="chain">
            <ibiblio name="central" m2compatible="true"/>
            <ibiblio name="neo4j-snapshot" m2compatible="true" root="http://repo.neo4j.org/content/repositories/snapshots"/>
        </chain>
        <url name="neo4j-snapshot-hack">
              <artifact pattern="http://repo.neo4j.org/content/repositories/snapshots/[organisation]/[module]/[revision]/[artifact]-[revision](-[classifier]).[ext]"/>
        </url>
    </resolvers>
    <modules>
        <module organisation="org.neo4j.app" name="neo4j-server" resolver="neo4j-snapshot-hack"/>
    </modules>
</ivysettings>

这将意味着可能会跳过旁路POM文件中的传递依赖项.如果POM不能正常工作,则无法提供帮助
