示例说明如何使用文件系统解析程序

Question

任何人都可以通过考虑解释我如何在Ivy中使用文件系统解析器和样本.

1. 我有ivy.xml文件,我已经定义了所有的dependecies但我希望我的文件系统中的jar不是来自maven存储库..？

2. 我在哪里放ivysettings.xml文件.

3. build.xml应该包含什么来使用ivysettings.xml,这样我就可以使用来自文件系统的jar而不是来自maven ..

Answer 1

该ivysettings.xml文件默认情况下位于同一目录下的ivy.xml文件.

可以使用常春藤设置任务指定备用位置

项目结构

位于lib目录中的第三方依赖项.

$ tree
.
|-- build.xml
|-- ivysettings.xml
|-- ivy.xml
|-- lib
|   |-- junit-4.10.jar
|   |-- slf4j-api-1.6.4.jar
|   `-- slf4j-simple-1.6.4.jar
`-- src
    |-- main
    |   `-- java
    |       `-- org
    |           `-- demo
    |               `-- App.java
    `-- test
        `-- java
            `-- org
                `-- demo
                    `-- AppTest.java

10 directories, 8 files

的ivy.xml

此常春藤文件使用配置来管理3种依赖项:

1. 编
2. 运行
3. 测试

这些将对应于ANT构建使用的类路径.

<ivy-module version="2.0">
    <info organisation="com.myspotontheweb" module="demo"/>

    <configurations defaultconfmapping="compile->default">
        <conf name="compile" description="Required to compile application"/>
        <conf name="runtime" description="Additional run-time dependencies" extends="compile"/>
        <conf name="test"    description="Required for test only" extends="runtime"/>
    </configurations>

    <dependencies>
        <!-- compile dependencies -->
        <dependency org="org.slf4j" name="slf4j-api" rev="1.6.4"/>

        <!-- runtime dependencies -->
        <dependency org="org.slf4j" name="slf4j-simple" rev="1.6.4" conf="runtime->default"/>

        <!-- test dependencies -->
        <dependency org="junit" name="junit" rev="4.10" conf="test->default"/>
    </dependencies>

</ivy-module>

ivysettings.xml

没有什么花哨.简单映射到lib目录中的jar :

<ivysettings>
    <settings defaultResolver="local"/>
    <resolvers>
        <filesystem name="local">
            <artifact pattern="${ivy.settings.dir}/lib/[artifact]-[revision].[ext]"/>
        </filesystem>
    </resolvers>
</ivysettings>

或者.....我将永远包括非本地罐子的Maven中央回购如下:

<ivysettings>
    <settings defaultResolver="central"/>
    <resolvers>
        <ibiblio name="central" m2compatible="true"/>
        <filesystem name="local">
            <artifact pattern="${ivy.settings.dir}/lib/[artifact]-[revision].[ext]"/>
        </filesystem>
    </resolvers>
    <modules>
        <module organisation="org.slf4j" resolver="local"/>
        <module organisation="junit" name="junit" resolver="local"/>
    </modules>
</ivysettings>

所述模块部指定哪个罐子应该在本地检索.

build.xml文件

最后是使用常春藤来管理类路径的构建逻辑.

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