Apache Ivy 简明教程

Apache IVY - Install Task

安装任务用于在解析器中安装模块及其依赖项。当要下载公共构建产出并在私有存储库中使用时，将用到该模块。默认情况下，用户本地存储库就是其私有存储库，位于 ${ivy.default.ivy.user.dir}/local。

Install task is used to install a module and its dependencies in a resolver. It is used when a public artifact is to be downloaded and used in private repository. By default, a user local repository is his/her private repository and is present in ${ivy.default.ivy.user.dir}/local.

让我们按照 IVY - Resolve Task 章节中的描述创建 Tester.java、build.xml 和 ivy.xml。

Let’s create Tester.java, build.xml and ivy.xml as described in IVY - Resolve Task chapter.

更新 build.xml 以使用 ivy install 任务。

Update the build.xml to use the ivy install task.

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。

Following are the important terms.

organisation − name of the organization.
module − module name of the project.
revision − version of the project.
from − from repository type.
to − to repository type.

Building the project

因为我们已准备好所有文件。只需转到控制台。导航至 E:\ivy 文件夹并运行 ant 命令。

As we’ve all the files ready. Just go the console. Navigate to *E: > ivy * folder and run the ant command.

E:\ivy > ant install

Ivy 将执行操作，解析依赖关系，您将看到以下结果。

Ivy will come into action, resolving the dependencies, you will see the following result.

E:\ivy > ant install

可以在 ivy 缓存的默认本地存储库位置 ${ivy.default.ivy.user.dir}> .ivy2 > local 目录中验证下载的文件。

You can verify the downloaded files in ivy cache’s default local repository location * ${ivy.default.ivy.user.dir} > .ivy2 > local* directory.
