I'm totally new with Ant, and I don't know how classpath works in Ant. I have wrote a Java class to do some scripting for me, and I wanted to deploy it as a task in Ant. The class uses commons-codec-1.2.jar as an external library, in other to do some Unicode and MD5 tasks for me. I've posted my build.xml file.
<?xml version="1.0" encoding="ISO-8859-1"?>
<project name="TcZip" basedir="." default="jar">
<property name="src.dir" value="src" />
<property name="classes.dir" value="classes" />
<property name="library.dir" value="library" />
<path id="external.classpath">
<pathelement location="${library.dir}/commons-codec-1.2.jar" />
</path>
<target name="clean" description="Delete all generated files">
<delete dir="classes" />
<delete file="TcZip.jar" />
</target>
<target name="compile" description="Compiles the task">
<mkdir dir="${classes.dir}" />
<javac srcdir="src" destdir="classes" />
<classpath>
<path refid="external.classpath" />
</classpath>
</target>
<target name="jar" description="JARs the Task" depends="compile">
<jar destfile="TcZip.jar" basedir="classes" />
</target>
<target name="use" description="Use the task" depends="jar">
<taskdef name="tczip" classname="ZipComparision" classpath="${ant.project.name}.jar" />
<tczip />
</target>
</project>
In my task directory, I have :
+task
- build.xml
- classes
- library
- src
library and classes contain the commons-codec-1.2.jar file. However, as seen in the build.xml file I have added a <property> tag for the library.
When I execute ant compile I get:
compile:
[javac] C:\workspace\task\build.xml:19: warning: 'includeantr

Could someone please help me with that?
Thank you
replace location in pathelement directive with path.

I am trying to deploy a web app to tomcat7. I read that tomcat provides the servlet libraries and confirmed this by looking in /usr/share/tomcat7/lib. Among others it contains:
servlet-api.jar, jsp-api.jar, annotations-api.jar, httpclient-4.5.3.jar
httpclient-cache-4.5.3.jar, httpcore-4.4.6.jar, httpclient-4.5.3.jar,
gson-2.6.2.jar
The relevant(I think) secion of build.xml is:
<path id="compile.classpath">
<!-- Include all JAR files that will be included in /WEB-INF/lib -->
<!-- *** CUSTOMIZE HERE AS REQUIRED BY YOUR APPLICATION *** -->
<pathelement location="${basedir}/lib/*"/>
<!-- Include all elements that Tomcat exposes to applications -->
<fileset dir="${catalina.home}/bin">
<include name="*.jar"/>
</fileset>
<pathelement location="${catalina.home}/lib"/>
<fileset dir="${catalina.home}/lib">
<include name="*.jar"/>
</fileset>
</path>
how come the app doesn't compile saying unknown symbol ? I also have those files in the project folder /lib:
symbol: class HttpSession
[javac] location: class QuestionPageServlet
[javac] /var/lib/tomcat7/webapps/FlashcardShark/src/flashcardshark/servlet/QuestionPageServlet.java:53: error: cannot find symbol
[javac] String responseMessage = new Gson().toJson("card successfully udpated");
[javac] ^
[javac] symbol: class Gson
[javac] location: class QuestionPageServlet
[javac] /var/lib/tomcat7/webapps/FlashcardShark/src/flashcardshark/servlet/QuestionPageServlet.java:56: error: cannot find symbol
[javac] response.setStatus(HttpServletResponse.SC_ACCEPTED);
[javac] ^
[javac] symbol: variable HttpServletResponse
[javac] location: class QuestionPageServlet
[javac] /var/lib/tomcat7/webapps/FlashcardShark/src/flashcardshark/servlet/QuestionPageServlet.java:66: error: cannot find symbol
[javac] HttpSession session = request.getSession();
EDIT: I download javaee-8 from oracles website set J2EE_HOME accordingly and added the following to the above section of the build file and it still does not compile:
<path id="compile.classpath">
<pathelement location="${basedir}/lib/*"/>
<fileset dir="${catalina.home}/bin"> <include name="*.jar"/>
</fileset>
<pathelement location="${catalina.home}/lib"/>
<fileset dir="${catalina.home}/lib">
<include name="*.jar"/>
</fileset>
<pathelement path = "${env.J2EE_HOME}/${j2ee.jar}"/>
<fileset dir = "lib">
<include name = "**/*.jar"/>
</fileset>
</path>
I am new to writing ant build scripts: but this is what I did to make it compile:
<javac srcdir="${src.home}"
destdir="${build.home}/WEB-INF/classes"
debug="${compile.debug}"
includes="${basedir}/lib/*"
deprecation="${compile.deprecation}"
optimize="${compile.optimize}">
the includes option on the is what did it.
I can´t compile following with JDK8 & Ant v1.9.4 with CLI.
build.xml:
<?xml version="1.0" ?>
<project default="Compile">
<target name="Compile">
<mkdir dir="classes"/>
<javac

Of course the package exists and it works within Eclipse, but not with the CLI! I only have this JDK installed, no other version, JAVA_HOME is set to JDK (not the included JRE)!
Any suggestions?
Many thanks and best regards

I have a project which used to compile and run fine. However, it complains when I try to use switch with Strings, with a java 7 compiler. I build this project using Ant.
The Ant config file (projectBuilder.xml) :
<?xml version="1.0"?>
<project name="TutoMigLayout" default="Main" basedir=".">
<!-- Sets variables which can later be used. -->
<!-- The value of a property is accessed via ${} -->
<property name="src.dir" location="src" />
<property name="lib.dir" location="lib" />
<property name="build.dir" location="bin" />
<!--

-->
<path id="build.classpath">
<fileset dir="${lib.dir}">
<include name="**/*.jar" />
</fileset>
</path>
<!-- Deletes the existing build directory-->
<target name="clean">
<delete dir="${build.dir}" />
</target>
<!-- Creates the build directory-->
<target name="makedir">

<!-- Compiles the java code -->
<target name="compile" depends="clean, makedir">

</target>

I get this in the console :

When I remove the compiler version from the compile target, I get that instead :

[javac] found : java.lang.String

I thought we could switch with Strings in Java 7 ?
If I click run one more time, I get a completely different message :
Error : could not find or load the main class test.Test
Edit : javac -version
javac 1.6.0_32
OK how do I change that ? I thought setting compiler compliance level to 1.7 and selecting jre7 was enough ?
Try adding a source="1.7" attribute. This controls the language features. However, in most cases both target and source attributes should be set to the same version. And, as mentioned by others, the compiler must support this version.

Is there something I'm missing that's needed to be included that was (or wasn't) mentioned in the tutorial?
EDIT: Based on Alex's inquiries, I tested to see if I had ant's junit jars in my shared directories (which I do):
$ ls /usr/share/ant/lib/ant-junit*.jar
/usr/share/ant/lib/ant-junit.jar /usr/share/ant/lib/ant-junit4.jar
I also tried to manually put ant-junit, ant-junit4.jar, and junit.jar into my project's lib directory, with the following results (all errors) after running ant clean junit:
junit.jar - /Users/jtyler/Projects/AntHelloWorld/build.xml:45: Reference application not found.
ant-junit.jar: package junit.framework does not exist
ant-junit.jar and ant.junit4.jar: package junit.framework does not exist
ant-junit4.jar: package junit.framework does not exist
EDIT The whole error when only junit.jar is included in the lib folder and calling ant clean junit is:

The tutorial is misleading. The junit files that are included in ant do not work. I downloaded juinit and copied the jar file to the lib folder of the project and it now works fine.
On top of including the junit.jar file within my lib dir, I added the following line to my build.xml file right above the junit task declaration:
<path id="application" location="${jar.dir}/${ant.project.name}.jar"/>
which is a copy of the 'application' path id declaration within the 'run' task definition.
The application builds successfully, and I get the following output with ant junit (test failure is expected):
ant junit
Buildfile: /Users/jtyler/Projects/AntHelloWorld/build.xml

Comments the following questions would be greatly appreciated:
Is the fact I actually needed to include the junit.jar file in my lib folder something I should be concerned about? I would assume this is not necessary if ant's tutorial explicitly states "Because Ant has a built-in JUnit 3.8.2 you could start directly using it."
Is the fact I needed to define the 'application' path id outside of the run task definition a typo within the apache ant tutorial? Or are there other things I missed or should consider?
Thanks to all those that helped.
You must specify junit.jar itself in your compile and in your <junit> task's classpath. This is not automatically included in your compile:
<!-- Contains junit.jar and other needed test classes -->
<path id="junit.classpath">
<fileset dir="${junit.directory}"/>
</path>
<!-- Contains third party jars your code is dependent upon -->
<path id="main.classpath">
<fileset dir="${dependent.jar.dir}"/>
</path>
<!-- Your main Java source code directory -->
<property name="main.srcdir" value="${basedir}/src/main/java"/>
<!-- Your main Junit test directory source code -->
<property name="test.srcdir" value="${basedir}/src/test/java"/>
<!-- Where you're compiling your main classes to -->
<property name="main.destdir" value="${basedir}/target/classes"/>
<!-- Where you're compiling your test classes to -->
<property name="test.destdir" value="${basedir}/target/test-classes"/>
[...]
<!-- Compile Test Classes -->
<!-- Notice you have three classpath elements:
* Your main classes you compiled before
* Your test main classpath that your main classes
were dependent up
* The junit.jar classpath
-->
<javac destdir="${test.destdir}"
srcdir="${test.srcdir}">
<classpath>
<!-- Your non-test classes you compiled before -->
<pathelement path="${main.destdir}/>
</classpath>
<classpath refid="junit.classpath"/>
<classpath refid="main.classpath"/>
</javac>
<!-- Now run your unit tests: Note how you have the same
three classpath elements as before -->
<junit fork="yes">
<classpath>
<pathelement path="${main.destdir}"/>
<pathelement path="${test.destdir}"/>
</classpath>
<classpath refid="main.classpath"/>
<classpath refid="junit.classpath"/>

The idea being to create an ear with the content of my web app. When I run this (run as with order as in the file, from galileo) I get this:
Buildfile: C:\Client-was7.xml
<snip>init:

Why isn't the output:
init:
compile:
createWar:
createEar:
cleanUp:
BUILD SUCCESSFUL

?
Thanks
I think it may have to do with the depends targets. when you run create ear, you first run compile, and then create war, which also depends on compile and so on.
