的ivy.xml

Question

我是Ivy的新手，并且非常简单地尝试了它，用于获取中心Maven中Guava和Gson等常用库存储库：

<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%\.ivy2\cache\;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放在一个（任意）目录中，将源jar放在另一个目录中？

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

请注意，我使用Ivy via Ant，沿着以下行，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>

Answer 1

另一个SO answer描述了如何使用配置来保持依赖关系组分离。但是，这个问题可能需要多次声明依赖项以适应不同的常春藤配置。

尝试以下方法：

的ivy.xml

<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>

的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>

注意：已更新，可添加清除常春藤缓存的目标。

Build运行如下，以确保新下载工件：

$ ant clean-all resolve

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：

$ unzip -t ./lib/sources/gson-sources.jar

Answer 2

〜/ .ivy2只是ivy cache。

您必须将模式设置为ivy retrieve。这将定义下载依赖项的位置。

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

也许第二次检索来源：

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

这也可以，并将源和jar的依赖项放在不同的目录中：

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

这取决于您的存储库中如何指定源/罐。

并注意：在使用任务之前必须提交taskdef。

您应该将解析器定义为m2compatible：

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

Answer 3

我遇到了类似的问题，但是提供的解决方案并没有发挥作用。我有一个主ivy.xml文件没有定义任何配置，所以继承了创建的默认配置，你甚至没有注意到它（参见doc）。使用新制作的＆＃34; main＆＃34;所有依赖项上的conf都破坏了构建。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目标中，就像那样简单！

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>

加载在你的build.xml中：

<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>

如何告诉Ivy将下载的jar放入自定义目录？
