How to build jar-file with ant?

According to the training task, I need to create .jar-file with ant. There are no problems with the Assembly of ordinary classes that are in src .

But I have in project present logger, libraries to him and .properties file.

because of this, errors fly out:

[javac] error: package org.apache.logging.log4j does not exist

and

error: cannot find symbol
[javac] error: private static final Logger logger = LogManager.getLogger(Hello.class);

I have build.xml

<?xml version="1.0"?>
<project name="Runner" default="run">
    <!-- define names of directories -->
    <property name="src" location="src"/>
    <property name="build" location="build"/>
    <property name="classes" location="${build}/classes"/>
    <!-- define all targets -->
    <target name="compile">
        <mkdir dir="${classes}"/>
        <javac srcdir="${src}" destdir="${classes}" includeAntRuntime="false"/>
    </target>
    <target name="run" depends="compile">
        <java classname="${ant.project.name}" classpath="${classes}"/>
    </target>
    <target name="clean">
        <delete dir="${build}"/>
    </target>
    <target name="package" depends="compile">
        <jar destfile="${build}/${ant.project.name}.jar" basedir="${classes}">
            <manifest>
                <attribute name="Main–Class" value="${ant.project.name}"/>
            </manifest>
        </jar>
    </target>
</project>

I figured it out.

<path id="classpath">
    <fileset dir="${lib}">
        <include name="**/*.jar"/>
    </fileset>
</path>

<target name="init" depends="clean" description="starts">
    <tstamp/>
</target>

<target name="clean" depends="package-to-jar" description="clean up">
    <delete dir="${classes}"/>
    <delete file="${external-lib}"/>
</target>

<target name="package-to-jar" depends="package-external-lib" description="packing all project into a jar-file">
    <jar destfile="${jar}/${ant.project.name}.jar" basedir="${classes}">
        <manifest>
            <attribute name="Main-Class" value="${main-class}"/>
        </manifest>
        <zipfileset src="${external-lib}"/>
    </jar>
    <delete dir="${classes}"/>
    <delete file="${external-lib}"/>
</target>

<target name="package-external-lib" depends="compile" description="packing external libraries into a jar-file">
    <jar destfile="${external-lib}">
        <zipgroupfileset dir="${lib}">
            <include name="**/*.jar"/>
        </zipgroupfileset>
    </jar>
</target>

<target name="compile" description="compile the source">
    <mkdir dir="${classes}"/>
    <javac srcdir="${src}" destdir="${classes}" classpathref="classpath"/>
    <copy todir="${classes}">
        <fileset dir="${src}" excludes="**/*.java"/>
    </copy>
</target>

Firstly you need include required library folders to class path

<path id="class.path">
  <fileset dir="lib">
    <include name="**/*.jar" />
  </fileset>
</path>

and add reference to javac task in compile target

<target name="compile">
        <mkdir dir="${classes}"/>
           <javac srcdir="${src}" destdir="${classes}" includeAntRuntime="false">
        <classpath refid="class.path" />
      </javac>
</target>

aftewards include all properties file to jar

<target name="package" depends="compile">
        <jar destfile="${build}/${ant.project.name}.jar" basedir="${classes}">
        <include name="*.properties"/>
            <manifest>
                <attribute name="Main–Class" value="${ant.project.name}"/>
            </manifest>
        </jar>
</target>
