Class-Path error in Ant Script
Hi,
I am writing my Ant build script according to the tutorial given
http://ant.apache.org/manual/tutorial-HelloWorldWithAnt.html here . I have
downloaded the Log4j from the site
http://www.apache.org/dist/logging/log4j/1.2.14/logging-log4j-1.2.14.zip. I
have copied the JAR file to my local directory
(D:\178010\AntScripts\Projects\lib).
I have created a java file in the path
D:\178010\AntScripts\Projects\src\cts\HelloWorld.java
package abc;
import org.apache.log4j.Logger;
import org.apache.log4j.BasicConfigurator;
public class HelloWorld
{
static Logger logger = Logger.getLogger(HelloWorld.class);
public static void main(String[] args)
{
BasicConfigurator.configure();
logger.info("Hello World"); // the old SysO-statement
}
}
and my build file is like this :
<u>build.xml</u>:
<project name="HelloWorld" basedir="D:\178010\AntScripts\Projects"
default="main">
<property name="src.dir" value="src"/>
<property name="build.dir" value="build"/>
<property name="classes.dir" value="${build.dir}/classes"/>
<property name="jar.dir" value="${build.dir}/jar"/>
<property name="main-class" value="abc.HelloWorld"/>
<property name="lib.dir" value="lib"/>
<path id="classpath">
<fileset dir="${lib.dir}" includes="**/*.jar"/>
</path>
<target name="compile">
<mkdir dir="${classes.dir}"/>
<javac srcdir="${src.dir}" destdir="${classes.dir}"/>
</target>
<target name="jar" depends="compile">
<mkdir dir="${jar.dir}"/>
<jar destfile="${jar.dir}/${ant.project.name}.jar"
basedir="${classes.dir}">
<manifest>
<attribute name="Main-Class" value="${main-class}"/>
</manifest>
</jar>
</target>
<target name="run" depends="jar">
<java fork="true" classname="${main-class}">
<classpath>
<path refid="classpath"/>
<path location="${basedir}/jar/HelloWorld.jar"/>
</classpath>
</java>
</target>
</project>
when I run the target "run" I am getting :
[javac] D:\178010\AntScripts\Projects\src\cts\HelloWorld.java:13:

g.apache.log4j does not exist
[javac] import org.apache.log4j.Logger;

or output for details.

What is wrong in the above code?
Thanks in advance,

You need log4j.jar in the compile-classpath
