如何告诉Ivy将下载的jar放到自定义目录中

Question

我是一个完全的Ivy新手，并且已经非常简单地尝试了它，用于获取常用的库，如Guava和Gson，这些库可以在Maven中央存储库中获得:

<ivy-module version="2.0">
    <info organisation="com.company" module="foobar"/>    
    <dependencies>
        <dependency org="com.google.guava" name="guava" rev="10.0.1"/>
        <dependency org="com.google.code.gson" name="gson" rev="2.0"/>
    </dependencies>    
</ivy-module>

在Windows上，默认情况下，Ivy将其文件存储在%USERPROFILE%.ivy2cache;在Unix-y系统上，它们在$HOME/.ivy2/下下载。

我想这是一个非常基本的问题:如何告诉Ivy下载二进制文件和源代码，并将二进制jar文件放在一个(任意)目录中，而将源jar文件放在另一个目录?

例如，我希望Ivy将所有下载的二进制jar文件放在[project_home]/WebContent/WEB-INF/lib中。

请注意，我是通过Ant使用Ivy的，按照下面的行，而不是IDE插件。

<project xmlns:ivy="antlib:org.apache.ivy.ant" name="ivy" default="resolve" > 
    <target name="resolve" description="retrieve dependencies with ivy">
        <ivy:retrieve/>
    </target>
    <path id="ivy.lib.path">
        <fileset dir="tools/buildlibs" includes="*.jar"/>
    </path>
    <taskdef resource="org/apache/ivy/ant/antlib.xml" uri="antlib:org.apache.ivy.ant" classpathref="ivy.lib.path"/>        
</project>

另一个SO答案描述了如何使用配置来保持依赖项组的分离。然而，这个问题可能需要多次声明依赖项，以适应不同的ivy配置。

尝试以下操作:

<标题>中

<ivy-module version="2.0">
    <info organisation="com.company" module="foobar"/>    
    <configurations>
        <conf name="sources"  description="Source jars"/>
        <conf name="binaries" description="binary jars"/>
    </configurations>
    <dependencies>
        <dependency org="com.google.guava" name="guava" rev="10.0.1" conf="sources->sources"/>
        <dependency org="com.google.code.gson" name="gson" rev="2.0" conf="sources->sources"/>
        <dependency org="com.google.guava" name="guava" rev="10.0.1" conf="binaries->default"/>
        <dependency org="com.google.code.gson" name="gson" rev="2.0" conf="binaries->default"/>
    </dependencies>    
</ivy-module>

<标题> build . xml

<project xmlns:ivy="antlib:org.apache.ivy.ant" name="hello-ivy" default="resolve">
    <target name="resolve" description="retrieve dependencies with ivy">
        <ivy:retrieve conf="sources" pattern="lib/[conf]/[artifact](-[classifier]).[ext]"/>
        <ivy:retrieve conf="binaries" pattern="lib/[conf]/[artifact](-[classifier]).[ext]"/>
    </target>
    <target name="clean" description="Remove build directories">
        <delete dir="lib"/>
    </target>
    <target name="clean-all" depends="clean" description="clean ivy cache">
        <ivy:cleancache />
    </target>
</project>

注:更新添加目标清除常春藤缓存

Build按如下方式运行，以确保工件是最新下载的:

$ ant clean-all resolve

<标题> 结果

$ find . -type f
./build.xml
./ivy.xml
./lib/sources/gson-sources.jar
./lib/sources/guava-sources.jar
./lib/binaries/gson.jar
./lib/binaries/jsr305.jar
./lib/binaries/guava.jar

证明源工件包含java文件:

Answer 2

~/。Ivy2只是ivy缓存

您必须为ivy retrieve设置一个模式。这将定义在哪里下载依赖项。

<ivy:retrieve pattern="${project_home}/WebContent/WEB-INF/lib/[artifact].[ext]" conf="jars"/>

也许是第二次检索的来源:

<ivy:retrieve pattern="${project_home}/sources/[artifact].[ext]" conf="sources"/>

这也可以工作，并将源和jar的依赖关系放在不同的目录中:

<ivy:retrieve pattern="${project_home}/[conf]/[artifact].[ext]" conf="sources, jars"/>

这取决于在你的存储库中如何指定源/jar。

另外: taskdef必须在使用任务之前出现。

您应该将解析器定义为m2compatible:

<ibiblio name="maven2" m2compatible="true"/>

Answer 3

我也遇到过类似的问题，但是有一个更棘手的情况，所提供的解决方案不起作用。我有一个主ivy.xml文件，没有定义配置，所以继承了默认的配置，你甚至没有注意到它(见文档)。在所有依赖项上应用新创建的"main"conf只会破坏构建。我别无选择，只能在另一个文件中定义一个新模块，比如ivy_extra.xml，并将其加载到一个新的目标中，就这么简单!

示例文件:

<!-- ivy_extra.xml -->
<ivy-module version="2.0">
    <info organisation="com.myorg" module="mymodule"/>
    <configurations>
        <conf name="download" visibility="private" />
    </configurations>
    <dependencies>
        <dependency org="com.google.guava" name="guava" rev="10.0.1" conf="download->default"/>
    </dependencies>
</ivy-module>

像这样载入你的build.xml:

<target name="download-guava" description="Retrieve guava">
    <echo>Retrieving guava</echo>
    <ivy:resolve file="ivy_agent.xml"/>
    <ivy:retrieve conf="download" type="jar" pattern="guava/[artifact]-[revision].jar"/>
</target>
