Below is a sample ant file for the purpose of this question.
Target "test1" is called from "test" using antcall. Now, when I have some classes having same fully qualified class names, I want the classes from test1.jar to be loaded first but it looks like test1.jar is appended to the classpath and hence classes from test.jar are picked instead.
Is there any way to reset/clear the classpath for target test1 or prepend test1.jar to the classpath so that classes from it are loaded.
<project name="TestProj" basedir=".">
<target name="test">
<java inputstring="" fork="true" failonerror="true" dir=".">
<classpath>
<fileset dir="C:/bb/" includes="test.jar"/>
</classpath>
</java>
</presetdef>
<antcall target="test1"/>
</target>
<target name="test1">
<java inputstring="" fork="true" failonerror="true" dir=".">
<classpath>
<path location="c:/test1.jar"/>
</classpath>
<jvmarg line="-Xms64m -Xmx512m"/>
<jvmarg line="-Dfile.encoding=UTF-8 -Djava.net.preferIPv4Stack=true"/>
</java>
</presetdef>
</target>
</project>
Try the following:
<path id="test.classpath">
<fileset dir="C:/bb/" includes="test.jar"/>
<path refid="compile.classpath"/>
</path>
<path id="test1.classpath">
<pathelement location="c:/test1.jar"/>
</path>
<project name="TestProj" basedir=".">
<target name="test">
<java inputstring="" fork="true" failonerror="true" dir=".">
<classpath>
<path refid="test.classpath"/>
</classpath>
</java>
</presetdef>
<antcall target="test1"/>
</target>
<target name="test1">
<java inputstring="" fork="true" failonerror="true" dir=".">
<classpath>
<path refid="test1.classpath"/>
</classpath>
<jvmarg line="-Xms64m -Xmx512m"/>
<jvmarg line="-Dfile.encoding=UTF-8 -Djava.net.preferIPv4Stack=true"/>
</java>
</presetdef>

I am a beginner in Ant and GWT and I was creating a new Ant project in GWT by following the steps mentioned on this GWT page: webAppCreator under the Creating an Ant project section. I was able to create this project successfully but I got the error build.xml does not exist! in the Command Prompt log. I am unable to fix this problem even after following all the steps mentioned here : ant build.xml file doesn't exist.
Here is my Command Prompt log:

Can someone please help me to fix this issue?
It seems your build.xml is created in a foo folder.
See this output:
Created file foo\build.xml
Go to the foo directory and then run ant.
C:\Users\TEST>ant build
Buildfile: build.xml does not exist!
Build failed
It means build file is absent in TEST directory. Checking your logs you have one in the :\Users\TEST\foo. So you should navigate into foo than try command via terminal one more time.
if you are on Mac :
brew install ant;
brew install ivy;
ant ivy-bootstrap ;
then go to top of ant project;
run ant
When I'm using external libraries (lucene) and running my java application through eclipse (run application) all works fine with the libs in the classpath.
But when I'm using Ant, i got this error here:
java.lang.ClassNotFoundException: org.apache.lucene.store.Directory
I guess this error shows up, cause of an incorrect classpath. Stange that no compilation error occurs, when ant compiles the code. This is my ant file:

Can you please help me here out?
It's not that strange, because ClassNotFoundException arises always when trying a dynamic instantiation (through Class.forName()). So it is possible that the same classpath produces a right compilation, but it is not complete for an execution: It lacks the dynamic dependencies.
In your case, you must add to the execution classpath the lucene-core library (at least).
I am trying to write a ant build which calls a Java class
<target name="validate" depends="forge-jar">
<taskdef name="spec" classname="SpecBuild" classpathref="java.classpath" />
<spec a="${forge}" mail="${mail}" dd="${dd}" wdd="${wdd}"/>
</target>
<target name="forge-jar" >
<path id="project.class.path">
<pathelement location="classes/" />
<pathelement path="classes/ant/tasks/SpecBuild.class" />
</path>
<path id="java.classpath">
<path refid="project.class.path" />
</path>
<javac includeantruntime="false" srcdir="src" destdir="classes" classpathref="java.classpath">
<filename name="**/SpecBuild.java" />
</javac>
</target>
In the SpecBuild.java class if I use slf4j logger I am getting this warning :-
CLASSPATH element /Users/classes/ant/tasks/SpecBuild.class is not a JAR.
[taskdef] CLASSPATH element /Users/classes/ant/tasks/SpecBuild.class is not a JAR.
Can anyone please help me fix this
You can specify the 'classes' directory in the class path as below. Remove the 'SpecBuild.class' file from pathElement location. You can either use 'includes' property and mention the file name in it or just include the 'classes' directory as below (exclude the JUni test cases package, if you have).
<classpath>
<pathelement path="${classpath}"/>
<fileset dir="lib">
<include name="**/*.jar"/>
</fileset>
<pathelement location="classes"/>
<dirset dir="${build.dir}">
<include name="apps/**/classes"/>
<exclude name="apps/**/*Test*"/>`enter code here`
</dirset>
</classpath>
Good luck.
The spark-de.jar used other jar files as libraries. Assume running spark-de.jar requires lib1.jar and lib2.jar, how to set them in the following Java task of Ant?
<target name="makeQuery">
<java classname="sparkDemo.SparkTest" failonerror="true">
<classpath>
<pathelement location="${basedir}/spark-de.jar"/>
</classpath>
</java>
</target>
This should do the trick:
<target name="makeQuery">
<java classname="sparkDemo.SparkTest" failonerror="true">
<classpath>
<pathelement location="${basedir}/spark-de.jar"/>
<pathelement location="${basedir}/lib1.jar"/>
<pathelement location="${basedir}/lib2.jar"/>
</classpath>
</java>
</target>

any help or pointer would be much appreciated ty!
com.sun.internal packages are NOT recommended to use , because
they are not guaranteed to be available across environments
support to those classes are also not guaranteed
