Apache IVY - 安裝任務

安裝任務用於在解析器中安裝模組及其依賴項。當需要下載公共製品並在私有儲存庫中使用時使用該任務。預設情況下，使用者本地儲存庫是其私有儲存庫且位於 ${ivy.default.ivy.user.dir}/local 中。

讓我們按照 IVY - 解析任務 章節中所述建立 Tester.java、build.xml 和 ivy.xml。

更新 build.xml 以使用 Ivy install 任務。

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>

以下是重要術語。

• 組織 − 組織名稱。

• 模組 − 專案的模組名稱。

• 修訂 − 專案的版本。

• 從 − 從儲存庫型別。

• 到 − 到儲存庫型別。

構建專案

由於我們已經準備好所有檔案。請轉到控制檯。導航到 E:\ivy 資料夾並執行 ant 命令。

E:\ivy > ant install

Ivy 將投入使用，解析依賴項，您將看到以下結果。

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