常春藤定制网址解析器

我正在尝试在ivysettings.xml文件中创建自定义解析器:

<ivysettings>
    <settings defaultResolver="default"/>
    <resolvers>
        <chain name="default">
            <url name="scala-tools">
                <ivy pattern="http://scala-tools.org/repo-releases/[organisation]/[module]/[revision]/ivy-[revision].xml" />
                <artifact pattern="http://scala-tools.org/repo-releases/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"/>
                <artifact pattern="http://scala-tools.org/repo-releases/[organisation]/[module]/[revision]/[artifact].[ext]"/>
            </url>
            <!--<ibiblio name="ibiblio"/>-->
        </chain>
    </resolvers>
</ivysettings>

正如您所看到的,我只有一个UrlResolver会尝试在scala-tools repo中找到我的依赖项。如果我指定我的依赖项correctly,那么常春藤将尝试在http://scala-tools.org/repo-releases/org.scala-lang/scala-library/2.8.0/scala-library-2.8.0.jarhttp://scala-tools.org/repo-releases/org.scala-lang/scala-library/2.8.0/scala-library.jar中找到它(是的,根据我在ivysettings.xml中的说明)显然,它没有找到任何内容。为了让事情有效,我必须以这种方式指定依赖关系:

<ivy-module version="2.2">
    <info organisation="org.yoba" module="Yoba"/>
    <dependencies>
        <dependency org="org/scala-lang" name="scala-library" rev="2.8.0"/>
        <!--<dependency org="org.scala-lang" name="scala-library" rev="2.8.0"/>-->
        <dependency org="org/scala-lang" name="scala-compiler" rev="2.8.0"/>
        <!--<dependency org="org.scala-lang" name="scala-compiler" rev="2.8.0"/>-->
    </dependencies>
</ivy-module>
问:如何改变工件模式/其他东西迫使常春藤使其正常工作?

<强>的ivy.xml

我检查了POM的scala-compiler并发现它引用了模块scala-library。这意味着在常春藤文件中只需要一个依赖声明:

<ivy-module version="2.0">
    <info organisation="org.yoba" module="Yoba"/>
    <dependencies>
        <dependency org="org.scala-lang" name="scala-compiler" rev="2.8.0" conf="default"/>
    </dependencies>
</ivy-module>
  • 版本号必须为“2.0”
  • 包括默认映射以避免下载可选依赖项

<强> ivysettings.xml

我建议从任何符合Maven标准的存储库下载时使用ibiblio解析程序。

<ivysettings>
    <settings defaultResolver="scalatools"/>
    <resolvers>
        <ibiblio name="scalatools" root="http://scala-tools.org/repo-releases" m2compatible="true"/>
    </resolvers>
</ivysettings>

如果您需要下载其他库,可以增强设置文件,以便常春藤只从scala存储库中检索scala模块

<ivysettings>
    <settings defaultResolver="central"/>
    <resolvers>
        <ibiblio name="central" m2compatible="true"/>
        <ibiblio name="scalatools" root="http://scala-tools.org/repo-releases" m2compatible="true"/>
    </resolvers>
    <modules>
        <module organisation="org.scala-lang" resolver="scalatools"/>
    </modules>
</ivysettings>
