Apache IVY - 安装任务

安装任务用于在解析器中安装模块及其依赖项。当需要下载公共制品并在私有存储库中使用时使用该任务。默认情况下，用户本地存储库是其私有存储库且位于 ${ivy.default.ivy.user.dir}/local 中。

让我们按照 IVY - 解析任务 章节中所述创建 Tester.java、build.xml 和 ivy.xml。

更新 build.xml 以使用 Ivy install 任务。

build.xml

<project name="test" default="resolve" xmlns:ivy="antlib:org.apache.ivy.ant">
   <target name="resolve" description="resolve dependencies">
      <ivy:resolve />
   </target>
   <target name="install" description="install dependencies">
      <ivy:install organisation="commons-lang" module="commons-lang" 
         revision="2.6" transitive="true" overwrite="false" 
         from="public" to="local" />
   </target>
</project>

以下是重要术语。

• 组织 − 组织名称。

• 模块 − 项目的模块名称。

• 修订 − 项目的版本。

• 从 − 从存储库类型。

• 到 − 到存储库类型。

构建项目

由于我们已经准备好所有文件。请转到控制台。导航到 E:\ivy 文件夹并运行 ant 命令。

E:\ivy > ant install

Ivy 将投入使用，解析依赖项，您将看到以下结果。

E:\ivy > ant install
Buildfile: E:\ivy\build.xml
