Apache Ant is an application created in Java sponsored by the Apache foundation that allows automating tasks of compilation and construction of projects. As it is made in Java it is common to use it for Java projects.

Thanks to Apache Ant it is possible to save a lot of time in medium size projects. It is similar to the make tool, the difference is that it uses a file called build.xml where you specify the rules that the application will use.

With this in mind, it is very likely that if you develop applications with Java, you will use Ant.

So let’s install it on our Ubuntu 20.04 system.

Install Apache Ant on Ubuntu 20.04

1.- Install Java on Ubuntu 20.04

Apache Ant is a Java technology. It requires Java to run and therefore needs to be installed.

To avoid complications, we can install Java from the official Ubuntu repositories.

So, open a terminal session and execute the following command to update the system:

sudo apt update
sudo apt upgrade

Then, install Java:

sudo apt install openjdk-11-jre

Check that Java is running, showing the installed version:

java --version
openjdk 11.0.8 2020-07-14
OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu120.04)
OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu120.04, mixed mode, sharing)

Now we can continue.

Download and install Apache Ant

With Java installed, we can already start the download of Apache Ant using the wget command.

At the time of writing this post, the last stable version of Apache Ant is 1.10.8 so if you see this post in the future first check the version of Apache Ant and replace the current version by the new one.

So, start the download:

cd /tmp/
wget -c htps://downloads.apache.org/ant/binaries/apache-ant-1.10.8-bin.tar.gz
--2020-09-26 14:52:30-- https://downloads.apache.org/ant/binaries/apache-ant-1.10.8-bin.tar.gz

Then, decompress it and move the resulting folder to another location like /usr/local/ant so we can use the binary without problems.

tar xvzf apache-ant-1.10.8-bin.tar.gz
sudo mv apache-ant-1.10.8/ /usr/local/ant

To use Apache Ant on Ubuntu 20.04 from any location of the terminal, you have to modify the profile file.

sudo nano /etc/profile

And at the end of the file add the following:

ANT_HOME="/usr/local/ant"
PATH="$PATH:/usr/local/ant/bin"
export ANT_HOME
export PATH

Then save the changes and close the editor.

And to apply the changes in the file you run:

source /etc/profile

Now it’s time to test the installation.

Testing the installation

To verify that the installation has been correct just run the command ant.

ant

And you will have the next output on the screen:

Buildfile: build.xml does not exist!
Build failed

Although the output is an error, the reality is that Apache Ant is well installed because it requires a build.xml file that is not there but the binary is running.

You can also check the installed version of Ant.

ant --version

Output:

Apache Ant(TM) version 1.10.8 compiled on May 10 2020

So, Apache Ant is ready for battle.

Conclusion

Apache Ant is a very important tool for Java application development. With it, you can automate the process of compiling and building packages through predefined rules.

So now that you know how to install your latest version on Ubuntu 20.04, you can take full advantage of it.

Install Apache Ant on OpenSUSE 15.2 / 15.1

OpenSUSE is becoming more and more popular thanks to the stability it provides. And that pleases many Java developers. For this, we need Java and some other configurations.

Install Java on OpenSUSE 15.2 / 15.1

As Apache Ant is built in Java and its potential is better exploited in Java projects.

So you have to install Java on OpenSUSE 15.2 /15.1 but first, it is recommended to update the system.

So, open a terminal and run it:

:~$ sudo zypper up

This way the system will be updated and with the security patches correctly installed.

Java 11 is available in the official OpenSUSE 15.2 / 15.1 repositories through the OpenJDK project. To check it out, you can run the following command:

:~$ sudo zypper search openjdk

  | java-1_8_0-openjdk-src           | OpenJDK 8 Source Bundle            | package

So to install it, just run the following command:

:~$ sudo zypper in java-11-openjdk

The following 11 NEW packages are going to be installed:

Overall download size: 35,7 MiB. Already cached: 0 B. After the operation, additional 167,4 MiB will be used.
Continue? [y/n/v/...? shows all options] (y):

Finally, check the version of Java installed.

:~$ java --version
openjdk 11.0.6 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10-suse-lp151.3.12.1-x8664)
OpenJDK 64-Bit Server VM (build 11.0.6+10-suse-lp151.3.12.1-x8664, mixed mode)

Install Apache Ant on OpenSUSE 15.2 / 15.1

Now we can download and install Apache Ant on OpenSUSE 15.2 / 15.1

First locate the temporary folder and from there download with wget.

:~$ cd /tmp/
:~$ wget -c http://mirrors.advancedhosters.com/apache/ant/binaries/apache-ant-1.10.7-bin.tar.gz
--2020-03-26 18:33:15--  http://mirrors.advancedhosters.com/apache/ant/binaries/apache-ant-1.10.7-bin.tar.gz

Once the download is complete, unzip it and move it to /usr/local/

:~$ tar -xvf apache-ant-1.10.7-bin.tar.gz
:~$ sudo mv apache-ant-1.10.7/ /usr/local/ant

That’s enough to use it. However, it is a good idea to modify the bash profile so that Apache Ant is available from any directory and not from where it is copied.

So modify the profile configuration file:

:~$ sudo nano /etc/profile

And add the following to the end of the file:

ANT_HOME="/usr/local/ant"
PATH="$PATH:/usr/local/ant/bin"
export ANT_HOME
export PATH

Apply the changes with the following command:

:~$ source /etc/profile

Testing the installation

Now that Apache ant is installed we will do two tests to check that it works.

The first one will be to choose any directory and execute the command ant

:~$ ant

And you will have a screen output like this:

Buildfile: build.xml does not exist!
Build failed

If this is so, Ant is working well. Remember that apache Ant requires a build.xml file to perform the processes. This error indicates that ant is working, it just can’t find the file.

Finally, you can check the installed version:

:~$ ant -version
Apache Ant(TM) version 1.10.7 compiled on September 1 2019

So, Ant is ready to be used.

Conclusion

In this post you have learned how to install Apache Ant on OpenSUSE quickly and easily. Also with this method you will always have the latest stable version.
