‌Building a Java project cloned from git using Ant fails

Question

I'm trying to build JICOFO on an Ubuntu server 16.04.1. After installing default JDK & JRE and setting JAVA_HOME variable cloned JICOFO and tried to built it by following commands:

$ git clone https://github.com/jitsi/jicofo.git
$ cd jicofo
$ ant dist.lin64

When try to build project via ant dist.lin64 command first I got the following error:

/home/xaq/jicofo/build.xml:54: Problem: failed to create task or type antlib:org.apache.maven.artifact.ant:dependencies
Cause: The name is undefined.

After resolving Maven problem by copying maven-ant-tasks-2.1.3.jar to lib folder bunch of dependency errors occurs when trying to build the project.

My question is: How to automatically resolve all dependencies for building such a project? isn't it what Ant and Maven are proposed to do?!

Answer 1

To fetch all project dependencies I just ran the following command from where pom.xml file resides (here in jicofo folder):

$ mvn install

This command despite the name won't install Maven, instead it will fetch all project dependencies from appropriate repositories.

You need to have Maven installed before running this command. That's an easy job:

$ sudo apt-get install maven

Now $ ant dist.lin64 will build project successfully.
