动态更新 Ivy 额外属性

Question

我计划在 ivy.xml 文件中使用额外的属性，以便能够访问修订号部分，我需要这样做以便我可以在 ivysettings 中将这些值用于解析器模式.xml 文件：

<ivy-module version="2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:e="http://ant.apache.org/ivy/extra" xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd">
    <info organisation="MyCompany" module="MyModule" revision="1.2.3.4" e:shortrev="1.2.3" e:buildnum="4" publication="20120207140052" />
    ...
</ivy-module>

我想在构建过程中动态更新 shortrev 和 buildnum 额外属性，以便在发布此模块时，它们的值将与它一起保存，以便我可以将 ivysettings.xml 文件中的这些额外属性用于解析器模式。

<resolvers>
    <filesystem name="fs.resolver">
        <ivy pattern="${my.dir}/[organisation]/[module]/[shortrev]/[buildnum]/ivy.xml" />
        <artifact pattern="${my.dir}/[organisation]/[module]/[shortrev]/[buildnum]/[artifact].[ext]" />
    </filesystem>
</resolvers>

suggested 我可以尝试使用 Ivy 文件中的属性来动态设置它们的值，但我不清楚如何去做。

此示例使用来自 ANT 的标准 buildnumber 任务。不幸的是，ivy buildnumber 任务无法正确解析解析器定义中具有额外属性的模块:-(

示例

$ tree
.
|-- build.xml
|-- ivysettings.xml
|-- ivy.xml
`-- src
    `-- main
        `-- HelloWorld.java

ivy.xml

<?xml version="1.0" encoding="ISO-8859-1"?>
<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">
    <info organisation="MyCompany" module="MyModule" e:shortrev="${publish.target.revision}" e:buildnum="${publish.buildnumber}"/>

    <configurations defaultconfmapping="compile->default">
        <conf name="compile" description="Required to compile application"/>
        <conf name="runtime" description="Shared library needed at runtime" extends="compile"/>
        <conf name="test"    description="Required for test only" extends="runtime"/>
    </configurations>

    <publications>
        <artifact name="MyModule" type="jar" e:shortrev="${publish.target.revision}" e:buildnum="${publish.buildnumber}"/>
    </publications>

    <dependencies>
        <dependency org="commons-lang" name="commons-lang" rev="2.6"/>
        <dependency org="junit" name="junit" rev="4.8.2" conf="test->default"/>
    </dependencies>

</ivy-module>

注意事项：

• 额外的属性与 both 信息和工件定义相关联。

build.xml

<project xmlns:ivy="antlib:org.apache.ivy.ant" name="publish-example" default="build">

    <!--

    <property name="publish.target.revision" value="1.2.3"/>
    <property name="publish.status"   value="release"/>
    <property name="publish.resolver" value="custom.repository"/>

    <!--

    <target name='init' description='Resolve project dependencies and set classpaths'>
        <ivy:resolve/>

    <target name="compile" depends="init">
        <javac srcdir="${src.dir}" destdir="${classes.dir}" includeantruntime="false" classpathref="compile.path"/>
    </target>

    <target name="build" depends="compile">

        <ivy:publish resolver="${publish.resolver}" pubrevision="${publish.revision}" overwrite="true">

    </target>

    <target name="clean" description="--> clean project files">

    </target>

    <target name="clean-all" depends="clean" description="--> clean ivy cache">
        <ivy:cleancache />
    </target>

</project>

注意事项：

• ivy deliver 任务可确保正确填充已发布的 ivy 文件。

ivysettings.xml

<ivysettings>
    <settings defaultResolver="central"/>
    <resolvers>
        <ibiblio name="central" m2compatible="true"/>
        <filesystem name="custom.repository">
            <ivy pattern="${ivy.settings.dir}/repository/[organisation]/[module]/[shortrev]/[buildnum]/ivy.xml" />
            <artifact pattern="${ivy.settings.dir}/repository/[organisation]/[module]/[shortrev]/[buildnum]/[artifact].[ext]" />
        </filesystem>
    </resolvers>
</ivysettings>

注意事项：

• 我总是将 Maven Central 设置为我的默认解析器，以便检索第三方依赖项，例如 commons-lang 和 junit。
• custom.repository 解析器在构建文件中配置为属性“publish.resolver”
