Apache IVY - 資訊任務

資訊任務用於在檔案設定 ivy 特定資訊，並且無需任何依賴項解析即可使用。

讓我們建立 Tester.java、build.xml 和 ivy.xm，如 IVY - 解析任務 章節所述。

更新 build.xm，以使用 ivy publish 任務。首先，我們將建立一個 JAR 檔案，然後釋出它。在釋出任務之前，我們已經使用資訊任務設定了所需的 ivy 資訊。

build.xml

<project name="test" default="resolve" xmlns:ivy="antlib:org.apache.ivy.ant">
   <property name = "build.dir" value = "build"/>
   <target name="resolve" description="resolve dependencies">
      <ivy:resolve />
   </target>
   <target name = "jar">
      <jar destfile = "${build.dir}/lib/application.jar"
         basedir = "${build.dir}/classes">      
         <manifest>
            <attribute name = "Main-Class" value = "com.tutorialspoint.Application"/>
         </manifest>
      </jar>
   </target>
   <target name="publish" depends="jar">
      <ivy:info file="ivy.xml" />
      <ivy:publish resolver="local" pubrevision="1.0" overwrite="true">
         <artifacts pattern="${build.dir}/lib/[artifact].[ext]" />
      </ivy:publish>   
   </target>
</project>

在此，釋出任務首先構建 JAR，然後使用 ivy:info 任務設定資訊，再將製品釋出到本地儲存庫。

構建專案

由於我們已準備好所有檔案。只需轉到控制檯。導航到 E: > ivy 資料夾並執行 ant 命令。

E:\ivy > ant publish

Ivy 將開始執行操作，解析依賴項，您將看到以下結果。

Buildfile: E:\ivy\build.xml

jar:

publish:
 [ivy:info] :: Apache Ivy 2.5.0 - 20191020104435 :: https://ant.apache.org/ivy/
::
 [ivy:info] :: loading settings :: url = jar:file:/E:/Apache/apache-ant-1.9.14/l
ib/ivy-2.5.0.jar!/org/apache/ivy/core/settings/ivysettings.xml
[ivy:publish] :: publishing :: com.tutorialspoint#test
[ivy:publish]   published application to C:\Users\Acer\.ivy2\local\com.tutorials
point\test\1.0\jars\application.jar
[ivy:publish]   published ivy to C:\Users\Acer\.ivy2\local\com.tutorialspoint\te
st\1.0\ivys\ivy.xml

BUILD SUCCESSFUL

如果我們沒有放置資訊任務，釋出任務將無法正常工作。使用下面修改的 build.xm，檢視缺少組織屬性等錯誤。

build.xml

<project name="test" default="resolve" xmlns:ivy="antlib:org.apache.ivy.ant">
   <property name = "build.dir" value = "build"/>
   <target name="resolve" description="resolve dependencies">
      <ivy:resolve />
   </target>
   <target name = "jar">
      <jar destfile = "${build.dir}/lib/application.jar"
         basedir = "${build.dir}/classes">      
         <manifest>
            <attribute name = "Main-Class" value = "com.tutorialspoint.Application"/>
         </manifest>
      </jar>
   </target>
   <target name="publish" depends="jar">
      <ivy:publish resolver="local" pubrevision="1.0" overwrite="true">
         <artifacts pattern="${build.dir}/lib/[artifact].[ext]" />
      </ivy:publish>   
   </target>
</project>
