i need to install Java, jdk and ant for my first class of Introduction to CC in the university and I’m having troubles by running the command ant test:
1- I installed Java 11 :

openjdk version "11.0.24" 2024-07-16
OpenJDK Runtime Environment (Red_Hat-11.0.24.0.8-2) (build 11.0.24+8)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.24.0.8-2) (build 11.0.24+8, mixed mode, sharing)

2- I installed ant:

Apache Ant(TM) version 1.10.14 compiled on March 2 2024

3- I was provided by one build.xml and the instruction was to run the command ant run inside the library that contains the file build.xml, it seems working:

Buildfile: /home/emertech/Documentos/ICC1/code/build.xml

init:

compile:

dist:

run:
     [java] Escribe tu nombre y luego presiona enter: 
mateo
     [java] Hola mateo, esta es la terminal de java.

BUILD SUCCESSFUL
Total time: 5 seconds

4- Here comes the problem, when I ran the ant test it trows an error:

Buildfile: /home/emertech/Documentos/ICC1/code/build.xml

init:

compile:

compiletests:

test:

BUILD FAILED
/home/emertech/Documentos/ICC1/code/build.xml:51: Problem: failed to create task or type junit
Cause: the class org.apache.tools.ant.taskdefs.optional.junit.JUnitTask was not found.
        This looks like one of Ant's optional components.
Action: Check that the appropriate optional JAR exists in
        -/usr/share/ant/lib
        -/home/emertech/.ant/lib
        -a directory added on the command line with the -lib argument

Do not panic, this is a common problem.
The commonest cause is a missing JAR.

This is not a bug; it is a configuration problem

I already check the junit.jar is in the lib dir of ant

/usr/share/ant/lib$ ls
ant-bootstrap.jar  ant.jar  ant-launcher.jar  hamcrest  hamcrest.jar  junit.jar

If someoane can help me i really preciate that because the guy that helps the proffesor only says tat he did not know and is better to install ubuntu, I’m working in fedora distro.

I already tried to install junit and ant again but the ant test crashes
