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。
让我们按照 IVY - Resolve Task 章节中的描述创建 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。
-
organisation − 组织名称。
-
module − 项目的模块名称。
-
revision − 项目版本。
-
from − 来自存储库类型。
-
to − 到存储库类型。
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。
E:\ivy > ant install
Ivy 将执行操作,解析依赖关系,您将看到以下结果。
E:\ivy > ant install
Buildfile: E:\ivy\build.xml
