I'm using Enunciate to build a prototype REST api and need to include a jar containing custom code as a library.
My Ant Script looks like this:
<!--include all jars-->
<path id="en.classpath">
<fileset dir="${lib}">
<include name="**/*.jar" />
</fileset>
</path>
<!--define the task-->
<taskdef name="enunciate" classname="org.codehaus.enunciate.main.EnunciateTask">
<classpath refid="en.classpath" />
</taskdef>
<mkdir dir="${dist}" />
<enunciate dir="${src}" configFile="${basedir}/enunciate.xml">
<include name="**/*.java" />
<classpath refid="en.classpath"/>
<export artifactId="spring.war.file" destination="${dist}/${war.name}" />
</enunciate>
The problem is that my custom jar is being excluded from the WAR file. It is necessary to compile the enunciate annotated classes so the jar is obviously on the classpath at compile time but enunciate is failing to include it in the distribution. I have also noticed that several of the jars needed by enunciate are not being included in the WAR file.
Why are they being excluded and how do I fix it?
I never used enunciate, but as a quick hack you can add the jars to the war:
<jar jarfile="${dist}/${war.name}" update="true">
<fileset dir="${lib}">
<include name="**/*.jar" />
</fileset>
</jar>
Note: you probably want to add the jars to the WEB-INF/lib directory, instead of the root directory.
I'm guessing that enunciate does the mininum to interfere with your own build process, since you know best what to put within your jar file.
As it turns out one of the jars we're attempting to include has a dependency listed in it's Manifest file of a jar that Enunciate depends on (freemarker). Enunciate automatically excludes freemarker and at first glance it seems as though it automatically excludes anything that depends on freemarker as well. If we remove freemarker from the list of dependent jars in our code's manifest file it works just fine.
However; I've spoken with the main developer of Enunciate (Ryan Heaten) and he assures me this isn't what's happening. Including his response below:
Really?!
Wow. Interesting. I can't explain
it; Enunciate doesn't look at what's
in the Manifest in order to determine
what to include in the war, so I'm
kind of stumped here. It could also
be some weird Ant behavior (not
including that jar in the
"en.classpath" reference for some
reason).
~Ryan
In enunciate.xml I tell it not to copy any libs itself:
<webapp doLibCopy="false">
Then in the ant build file at the end of the enunciate task I update the war (you can do this to update the included/excluded jars whether or not you have Enunciate copy the jars for you in the step above):
<war destfile="build-output/{mywar}" update="true">
<lib dir="WebContent/WEB-INF/lib">
<include name="**/*.jar" />
</lib>
<lib dir="build-output">
<include name="some_other.jar" />
</lib>
</war>

I'm attempting to add a splash-screen to a large Java project. The application is compiled into an executable .jar file using ANT.
I am able to get the splash screen working easily from NetBeans by simply adding -splash:src/com/.../.../image.PNG to my main project's VM options. However, adding SplashScreen-Image: com/.../.../image.PNG to my manifest file fails with "SplashScreen.getSplashScreen() returned null"
I have already opened up my .jar archive to confirm that things were set up correctly: my META-INF\MANIFEST.MF file includes the SplashScreen-Image line. I have tried moving it before or after Main-Class. My actual image.PNG is also in the archive, in the correct path location.
I compile this java project with ANT, which I can guess is the source of my problems (I was able to make a simple, "jar cmf ..." example work just fine).
I use the following to get the project elements ready for achiving:
<target name="compile" depends="init"
description="Compile the source">
<!-- Compile the java code from ${src} into ${build} -->
<path id="lib.path.ref">
<fileset dir="${path_to_jre}" includes="*.jar"/>
</path>
<javac srcdir="${src}" destdir="${build}" source="${java_ver}" target="${java_ver}"
includeantruntime="false">
<!--compilerarg value="-Xbootclasspath/p:${toString:lib.path.ref}" compiler="javac1.7"/-->
<compilerarg value="-Xlint:unchecked"/>
<classpath>
<fileset dir="${LibDir}">
<include name="*.jar"/>
</fileset>
<pathelement path="${dependant_jar}"/>
<pathelement path="${another_dependant_jar}"/>
</classpath>
</javac>
<!-- Copy the .png files -->
<copy todir="${build}">
<fileset dir="${src}" casesensitive="false">
<include name="**/*.PNG"/>
</fileset>
</copy>
</target>
Notice that I use a copy to move .PNG files in with .class files. My image.PNG for the Splash Screen is just in with the others. I added it to my netbeans project by simply copying it there - nothing fancy.
My achieve target is as follows:
<target name="archive" depends="compile"
description="Generate the .jar file">
<!-- Put everything in ${build} into the .jar file -->
<jar jarfile="${jarfile}" basedir="${build}">
<!-- Merge in contents of dependency .jars -->
<zipfileset src="${LibDir}/snakeyaml.jar"/>
<zipfileset src="${dependant_jar}"/>
<zipfileset src="${another_dependant_jar}"/>
<!-- Specify main class in manifest -->
<manifest>
<attribute name="SplashScreen-Image" value="com/../../image.PNG"/>
<attribute name="Main-Class" value="${mainclass}"/>
</manifest>
</jar>
</target>
So my manifest in the eventual .jar is created here, which is also where I eventually realized to add the splashscreen tag.
I am somewhat new to working with ANT, so any advice regarding how to handle this or what to look for is appreciated.
It is not an issue with Ant. The problem is that the -splash option takes a file name, but the SplashScreen-Image manifest attribute must refer to a jar entry. If com/example/brian/image.PNG isn’t in the .jar file, it won’t be usable by SplashScreen-Image. The purpose of a .jar file is to be act as a self-contained module or application, so it should include all of the resources it needs.
The solution is to include the image in your .jar file:
<jar jarfile="${jarfile}" basedir="${build}">
<fileset dir="${src}" includes="**/*.PNG"/>
Update: Your build file was already adding the images to the .jar with a <copy> task, and I failed to notice it.
I have a solution, although I'm sure someone else will understand this better than I do.
I was able to run, with a splash-screen, using the Java binary in ../jre/lib/Java.exe, however I had initially been working from ../lib/Java.exe.
Looks like this is a known bug? Link here: https://bugs.java.com/bugdatabase/view_bug.do?bug_id=7129420. I guess the path to the SplashScreen dll is hardcoded.
Note: Thanks to user VGR for the exhaustive help.
I need to include some third party jar file to my project jar. I mentioned it in my build.xml and include this to MANIFEST.MF. Now i get thirdparty1.jar thirdparty2.jar file into inside the project jar. But still i can't able to use the jars. Is it need any addition configuration
Here is my build.xml
<manifest>
<attribute name="Class-Path" value="thirdparty1.jar thirdparty2.jar thirdparty3.jar"/>
If i copy the two jar separately it works well. But i don't understand what is the need for copy these separate. How it solve with out copying jar separately.
If the dependency jar is packaged inside the project jar, you need a solution to load it from there. The standard class-path handling in Java won't access jar files located inside other jar files.
See this answer: Classpath including JAR within a JAR. Specifically the One Jar solution: http://one-jar.sourceforge.net/.
It's also possible to use zipgroupfileset for that.given is the sample ant task for that.
<!-- Build JAR file -->
<target name="jar" depends="init-build-dir,compile-main">
<!--creating a temp jar contains all jar -->
<jar jarfile="${project.build.lib.dir}/external-libs.jar">
<zipgroupfileset dir="${project.lib.redist.dir}">
<include name="**/*.jar" />
</zipgroupfileset>
</jar>
<sleep seconds="1" />
<!-- creating main jar with temp jar-->
<jar jarfile="${project.build.lib.dir}/${ant.project.name}.jar" manifest="MANIFEST.MF">
<fileset dir="${project.build.main.classes.dir}" includes="**/*.*" />
<zipfileset src="${project.build.lib.dir}/external-libs.jar">
<exclude name="*" />
</zipfileset>
</jar>
<!--removing temp jar -->
<delete>
<fileset dir="${project.build.lib.dir}">
<include name="external-libs.jar" />
</fileset>
</delete>
</target>
I have a package(with some outdated Java files) which i need to build using ant tool. I have some updated classes for which source is not available. So, I need to add the updated class to the jar during build and skip the outdated Java files from the build. Please let me know how to achieve this.
For example - I dont have the updated source java file for com.org.auth.ABC.Java, but i have the updated class file which i got from the another source ie com.org.auth.ABC.class. During build i need to point to the updated class(com.org.auth.ABC.class) for this class alone and create a new jar.
Please find how i am currently pointing to the class files below.
<target name="xxx.jar" depends="xjc,compile">
<jar destfile="${dist.dir}/xxx.jar">
<fileset dir="${classes.dir}" includes="**/*.class"/>
<fileset dir="${jaxb-classes.dir}" includes="**/*.class"/>
<fileset dir="${jaxb-source.dir}" includes="**/bgm.ser,**/jaxb.properties"/>
</jar>
</target>
If you want to leave some package from compilation you can use excludes attribute of fileset ant tag.
for example:
<fileset dir="src/">
<exclude name="**/dir_name_to_exclude/**" />
</fileset>
In order to include the specified class in compilation you can put the containing folder in your class-path using ant.
<path id="project.class.path">
<pathelement location="lib/"/>
<pathelement path="${java.class.path}/"/>
<pathelement path="path to your class file's base folder"/>
</path>
<javac srcdir="${src.dir}"
destdir="${classes.dir}"
classpathref="project.class.path">
... put source files here..
</javac>
And if you want to include that class-file in your jar then add it to fileset using include tag:
<fileset dir="classfiles">
<include name="your class file name"/>
</fileset>
Hope this helps
Since last update of ADT & build tools, I cannot build my application via the ant release request.
The ant output shows multiple "cannot find symbol" errors when referencing a class file located in a subfolder of libs/.
I tried modifying ant's build.xml as following :
<path id="java.compiler.classpath">
<fileset dir="${jar.libs.dir}">
<include name="**/*.jar **/*.class" />
</fileset>
</path>
But it doesn't work.
Compiling via Eclipse is fine.
I am truly not an ant expert, but is there something obvious I am missing ?
EDIT :
I tried updating ant and it changes nothing.
I also tried replacing the code above by the following, without success :
<path id="java.compiler.classpath">
<fileset dir="${jar.libs.dir}">
<include name="**/*.jar" />
</fileset>
<pathelement location="${jar.libs.dir}" />
</path>
Any ideas ?

Try this, you might be able to find the solution due to the update.
If not that..maybe this one..

I don't think your include is correct. I think you need to do it like this:
<include name="**/*.jar" />
<include name="**/*.class" />
Here is a way I've done it previously:
<fileset dir = "${lib}" includes = "**/*.jar"/>
<fileset dir = "${webLib}" includes = "**/*.jar"/>
How can I use Ant to download and unpack java jars while only specifying the list of jars once? The key here is having one list of jars and generating:
a list of URLs to download with a get task
a classpath/fileset of the same jars locally
I'd really only like to specify the list of jars once.
<property name="dependency.lib.dir" location="dependencies" />
<mkdir dir="${dependency.lib.dir}" />
<get dest="${dependency.lib.dir}">
<url url="http://server1/lib1.jar"/>
<url url="http://server2/lib2.jar"/>
</get>
<fileset id="dependency.libs" dir="${dependency.lib.dir}">
<include name="*.jar" />
</fileset>
<path id="project.debug.classpath">
<fileset refid="dependency.libs" />
</path>
You can add additional sub-elements to the <path> if you have a local lib directory.
As far as I can tell, this is not possible with ant.
