Apache Ivy 简明教程

Apache IVY - Info Task

info 任务用于在文件中设置 ivy 专有信息，且无需进行任何依赖项解析就可使用。

info task is used to set ivy specific information in a file and can be used without any dependency resolution.

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 发布任务。我们首先将创建 jar 文件，然后发布它。在发布任务之前，我们已使用 info 任务设置了所需的 ivy 信息。

Update the build.xml to use the ivy publish task. First we’ll create a jar file and then publish it. Before publish task, we’ve set the required ivy information using info task.

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>

此处发布任务首先构建 jar 文件，然后使用 ivy:info 任务设置信息，然后将工件发布到本地仓库。

Here publish task first build the jar, then set the information using ivy:info task and then publish the artifact to local repository.

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 publish

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.

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

[ivy:publish]   published ivy to C:\Users\Acer\.ivy2\local\com.tutorialspoint\te
st\1.0\ivys\ivy.xml

BUILD SUCCESSFUL

如果我们不设置 info 任务，则发布任务将不起作用。使用下面修改后的 build.xml，并查看缺少组织属性等错误。

If we do not put the info task then publish task will not work. Use the below modified build.xml and see the error for missing organization attribute and so on.

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>

导航到 *E: > ivy * 文件夹并运行 ant 命令。

Navigate to *E: > ivy * folder and run the ant command.

E:\ivy > ant publish
