This topic is about Apache IVY – Install Task.
Install task is used to install a module and its dependencies in a resolver. It is used when a public artifact is to be downloaded and used in private repository. By default, a user local repository is his/her private repository and is present in ${ivy.default.ivy.user.dir}/local.
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 install task.
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>
Following are the important terms.
- organisation − name of the organization.
- module − module name of the project.
- revision − version of the project.
- from − from repository type.
- to − to repository type.
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 install
Ivy will come into action, resolving the dependencies, you will see the following result.
E:\ivy > ant install
Buildfile: E:\ivy\build.xml
