Question

Explain how Ant can be integrated with continuous integration systems, such as Jenkins or TeamCity. Provide examples of key steps in configuring these integrations

Answer 1

Ant can be integrated with continuous integration systems like Jenkins or TeamCity to automate the build process. Here’s how:

1. Install Ant on the CI server and configure environment variables (e.g., ANT_HOME, PATH).

2. In Jenkins:
a. Create a new job and select “Freestyle project.”
b. Under “Source Code Management,” choose your version control system and provide repository details.
c. In “Build Triggers,” enable desired triggers (e.g., polling SCM).
d. Add “Invoke Ant” as a build step, specifying targets and properties.

Example:

<target name="build">

<javac srcdir="${src}" destdir="${bin}"/>

</target>

3. In TeamCity:
a. Create a new project and link it to your VCS root.
b. Add a build configuration and specify the build steps.
c. Choose “Ant” as the runner type, providing build file path, targets, and properties.

Example:

<property name="teamcity.build.checkoutDir" value="."/>

<target name="compile">

<javac srcdir="${src.dir}" destdir="${build.dir}"/>

</target>
