Javadoc task in Ant build fails

I'm receiving an error message from Ant when I try to run the Javadoc ant task.

My other projects on the repository have similar configurations.
They work as expected.
Am I missing something obvious?
I did miss something obvious. An extra 't' in the property packages. Evidently, I'm going to need two sets of eyes for this or a fresh set, a few hours later!
NOW, how do I close this?

I think the problem is in following part:
<fileset dir="${src.dir}">
<include name="*.java" />
</fileset>
In Ant "*.java" means all files with names matching *.java. This does not search in subdirectories.
To include all subdirectories you must specify:
<fileset dir="${src.dir}">
<include name="**/*.java" />
</fileset>
But since you already specified the sourcePath attribute I'm wondering if you can't just remove the fileset element as ant will add **/*.java by default.

Configuration required for ant xml to build correct jar using java 1.8.0_40 and ant 1.9.0

I am trying to build jar for my project using jdk 1.8.0_40 and ant version 1.9.0, jar is getting build but while converting this jar to .exe, it is not able to find main class as I have correctly mentioned my main class.I am using eclipse Mar Version: Mars.2 Release (4.5.2).
Earlier I was using jdk 1.7.0_79 version and ant 1.8.4 and everything was working fine.
I am facing issue while upgrading from jdk 1.7.0_79 to jdk 1.8.0_40.
Below is my ant xml which are using to build my jar.Let me know if any configuration is required for java 1.8 to build proper jar.

In your java task you are using ./${jar.name} as the location of your jar - this is relying on the current directory being set correctly. All the rest of your code uses ${jar.dir}/${jar.name} as the path for the jar, so change the java task to do the same:
<target name="run">
<java fork="true" classname="${Main-Class}">
<classpath>
<path location="${jar.dir}/${jar.name}" />
</classpath>
</java>

Error creating jar archive contains more than 65535 entries

I am trying to build a jar file and getting error Build Failed.
Problem creating jar: archive contains more than 65535 entries. (and the archive is probably corrupt but I could not delete it)

Specify the zip64Mode argument on your jar task to say that you need to use the large 'zip64' format:
<jar destfile="${jar.dir}/${jar.name}" zip64Mode="always">

What is cause of the error ?

ant: the generated JAR cannot be executed

I've written/copied a simple ant example and am trying to deploy a Java progamm with it. My build file bsp0201.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<project name="bsp0201" default="main" basedir=".">
<property name="dir.src" value="./source" />

<fileset dir="${dir.build}" includes="**/*.class" />
</jar>
</target>
<target name="run" if="test">
<java classname="main.GeoAnalyzerMain" classpath="${dir.lib}/ae.jar">
<arg line="${test}" />
</java>
</target>
</project>
My ant commando & the result output:
# ant -f bsp0201.xml run -Dtest=Echo
Buildfile: /var/www/sandbox/ant/bsp0201/bsp0201.xml
run:
BUILD SUCCESSFUL
Total time: 1 second
Ant generates the folders, the class files and a JAR file ae.jar. But the size of this JAR file is only 19.1 KB (instead of 297 KB of the JAR file, when I generate it with eclipse) and I cannot execute it. What do I do wrong?
Thx

Yes, was a good idea to compare the JARs. :) Here you can see the comparsion result:
The folder /img and the /.classpath are missing in the Ant-JAR. Why has Ant not included them? How can I make Ant to include the missing files/folders?

I edited the build XML:
<?xml version="1.0" encoding="UTF-8" ?>
<project name="bsp0201" default="main" basedir=".">
<property name="dir.src" value="./source" />
<property name="dir.build" value="./classes" />
<property name="dir.lib" value="./lib" />
<path id="cp">
<pathelement path="${classpath}" />
<pathelement location="${dir.build}" />
</path>
<target name="main" depends="prepare, compile, run" />
<target name="prepare">
<mkdir dir="${dir.build}" />
<delete>
<fileset dir="${dir.build}" includes="**/*" />
</delete>
</target>
<target name="compile">
<javac classpathref="cp" destdir="${dir.build}" srcdir="${dir.src}" includes="**/*.java" includeantruntime="false" />
<mkdir dir="${dir.lib}" />
<jar destfile="${dir.lib}/AntExample.jar">
<fileset dir="${dir.build}" includes="**/*.class" />
<fileset dir=".">
<include name="img/*.*" />
</fileset>
</jar>
</target>
<target name="run" if="test">
<java classname="main.GeoAnalyzerMain" classpath="${dir.lib}/AntExample.jar">
<arg line="${test}" />
</java>
</target>
</project>
Now the image folder is copied into the result archive. But the JAR still cannot be executed.
EDIT:
It works!
