Apache IVY - Info Task

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

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

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

build.xml

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

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

Building the project

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

E:ivy > ant pubpsh

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

Buildfile: E:ivyuild.xml

jar:

pubpsh:

If we do not put the info task then pubpsh 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="antpb:org.apache.ivy.ant">
   <property name = "build.dir" value = "build"/>
   <target name="resolve" description="resolve dependencies">

   </target>
   <target name = "jar">
      <jar destfile = "${build.dir}/pb/apppcation.jar"
         basedir = "${build.dir}/classes">      
         <manifest>
            <attribute name = "Main-Class" value = "com.tutorialspoint.Apppcation"/>
