How to add tomcat's lib in ant build's classpath? - eclipse

I needed servlet-api.jar and jsp-api.jar in my eclipse dynamic web
project.
So I went to Project -> Properties -> Targeted Runtimes -> Checked Apache Tomcat 6.0.
Now I try to build a war file using Ant as I have to deploy the war file on a unix machine.
Problem - Ant build fails (package javax.servlet does not exist, etc etc) because the jar files are not under /WEB-INF/lib/. How do I include these jar files in the classpath ? I can't hardcode it as the path is different in windows(D:\Program Files\Apache...) and unix(/usr/local/apache..).
Current classpath-
<path id="compile.classpath">
<fileset dir="${web.home}/WEB-INF/lib">
<include name="*.jar"/>
</fileset>
</path>
p.s. My Apache-Tomcat versions are different on windows(6.0.32) and unix(6.0.36)

I would check if a variable like CATALINA_HOME is set on any machine where the build might run, then you could use something like:
<path id="compile.classpath">
<fileset dir="${web.home}/WEB-INF/lib">
<include name="*.jar"/>
</fileset>
<fileset dir="${env.CATALINA_HOME}/lib">
<include name="*.jar"/>
</fileset>
</path>

Try this:
Double click on your build.xml -> Run as -> Ant build...
Choose "Classpath" and add the jars needed
I think that should be enough

eclipse.buildScript Complete Example Script for headless build

I am trying to generate a build script for a plugin outside the IDE
Below is mybuild.xml
<project name="com.foo.poo" xmlns='antlib:org.apache.tools.ant'>
<target name="build.plugin">
<antcall target="generateBuildScript" />
<ant dir="${workspace.dir}/${project.name}"
antfile="build.xml"
target="build.update.jar" />
<copy todir="${eclipse.dir}/plugins">
<fileset dir="${workspace.dir}/${project.name}">
<include name="*.jar"/>
</fileset>
</copy>
</target>
<target name="generateBuildScript">
<eclipse.buildScript elements="plugin#${project.name}"
buildDirectory="${workspace.dir}"
baseLocation="${eclipse.dir}"
configInfo="linux,gtk,win32,win32,x86"/>
</target>
</project>
Expecting build.xml to be generated Please Guide me
When I run above script
$java -jar {$Eclipse.Dir}/plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar -application org.eclipse.ant.core.antRunner -buildfile <Project_path>\mybuild.xml
I nothing is happening on build success.
Here i have found the answer may help some new bees like me..
<project name="com.foo.poo" xmlns='antlib:org.apache.tools.ant'>
...
</project>
As there is no default set, it is not generating the required jar file so
modified only the first line as
<project name="com.foo.poo" default="build.plugin" xmlns='antlib:org.apache.tools.ant'>
...
</project>
now the required jar is generated under plugin folder and even copied to plugin folder of eclipse.
baseLocation : Target Plugins Directory absolute path.
buildDirectory: Absolute path to the plugin folder in which the Plugin Project is present.

Unable to deploy JavaFX applicaiton with external libraries in a JAR

I'm developing a JavaFX application in Eclipse. The app has external libraries, like log4j and others and runs perfectly from Eclipse. I've tried deploying it from Eclipse as a Runnable jar through the Eclipse built-in feature, and it runs well on some computers, while on others it would give me an obscure Undefined Link error. After digging around it seems JavaFX needs to be specially packaged either through an ANT script or through the javafxpackager application.
For the life of me I can't seem to deploy a runnable jar through either of those methods. Trying either of those methods, I get an Exception. Things I've tried:
Build the JavaFX application through an ANT script, below is a snippet of the relevant parts of the build script
<path id="classpath">
<fileset dir="${lib.dir}" includes="**/*.jar"/>
<fileset dir="${javafx.sdk.path}/jre/lib" includes="jfxrt.jar"/>

</manifest>
</fx:jar>
</target>
Compiling/generating the jar through the ant script, I get a window pop up for half a second and "Exception in Application start method" in the console, with no stack trace. I've tried runnning java with the -XX:-OmitStackTraceInFastThrow flag, but it still won't give me a stack trace.
Running through javafxpackager gives the following error:

You can deploy your application using javafxpackager. If you deploy a self contained application, the Java Runtime Environment will be bundled with your application and it will run on any machine whether the right version of Java is installed or not.
(You should have javafxpackager in your jdk directory under the bin folder.)
Look for your compiled files (.class) in your eclipse workspace folder. They should be in the bin directory.
Create a createjar folder and inside it create a classes and a out folder. Copy all of your .class files in the classes folder. Also include in the classes folder all jar needed by your application.
Now on the command line go inside the createjar directory and run this command :
"C:\path\to\jdk\jdk1.7.0_25\bin\javafxpackager.exe" -createjar -appclass package.MainClass -srcdir classes -outdir out -outfile NameOfYourJar -classpath "" -v
This should create a runnable jar in the out directory. You will need it for the next step.
Now create a deploy folder alongside the createjar folder.
Inside the deploy folder make to other directories dist and packages.
In the dist folder copy your freshly created jar from above plus all the dependencies/ressources it will need.
Go back on the command line (if you ever left it) and go in the deploy directory. Run the following command from there :
"C:\path\to\jdk\jdk1.7.0_25\bin\javafxpackager.exe" -deploy -native -outdir packages -outfile NameOfYourApp -srcdir dist -srcfiles NameOfYourJar.jar -appclass package.MainClass -name "Name of You Application" -title "Title of your application"
Once it is done it should have created all you need to deploy your app including native .exe file to run on Windows platform. This is the self contained application ! To be able to run it you need to go into bundles\NameOfYourApp\app and paste here all dependencies/ressource your app needs.
At last, double click on YourApp.exe and it should run even on machines without Java installed.
With ant files you have two main options: <fx:jar> and <fx:deploy>. The former just produces a jar that allows you to refer to your dependencies if they are in the same file as the jar. You can unpack the jar and look at the MANIFEST file produced to see how they are added to the javafx classpath.
<fx:deploy> allows you to pull in dependencies, but requires that you build a platform-specific installer. It can't be done using a jar. Apparently NetBeans allows you to create a stand-alone jar but I have not tested with that.
you do not package javafxrt.jar with your app
e(fx)clipse would have produced the ant-script for your if you use it

Getting an error "Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found."

I am getting an error Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found. when I am trying to ant build on eclipse. So I downloaded ant-contrib-0.6.jar and kept it in my /lib location of apache ant, but it still does not resolve my issue. I have also tried by specifying the /lib location in my CLASSPATH system variable. How can I get around this error?
You can provide full path to the ant-contrib JAR explicitly using "classpath" element:
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<pathelement location="${path-to-ant-contrib}/ant-contrib-1.0b3.jar"/>
</classpath>
</taskdef>
EDIT: Link contributed by Djacomo:
http://ant-contrib.sourceforge.net/
One important thing missing from this StackOverflow page is that setting the correct ANT_HOME env var is absolutely vital and important, without this setting ant keeps telling the same error, regardless of where you copy the ant-contrib-1.0b3.jar on your file systems. This missing thing has costed me a few hours. =)
However I receive this error without eclipse, in the pure ant.
I fixed that this way:
Add the JAR to the Ant runtime classpath entries.
Window>Preferences>Ant>Runtime>Classpath
Add the JAR to either Ant Home Entries or Global Entries.
It would appear that you haven't installed the ant contrib jar into the correct lib directory. This can be difficult to do if you have several installations of ANT.
My suggestion is to install your ANT plugins into the "$HOME/.ant/lib" directory. You could go one step further and automate the process as follows:
<project name="ant-contrib-tasks" default="all">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<target name="bootstrap">
<mkdir dir="${user.home}/.ant/lib"/>
<get dest="${user.home}/.ant/lib/ant-contrib.jar" src="http://search.maven.org/remotecontent?filepath=ant-contrib/ant-contrib/1.0b3/ant-contrib-1.0b3.jar"/>
</target>
<target name="all">
<for param="file">
<fileset dir="." includes="*.txt"/>
<sequential>
<echo message="Found file #{file}"/>
</sequential>
</for>
</target>
</project>
Use the below mentioned code in your build xml:
<path id="ant.classpath">
<pathelement location="${ant.jarPath}/ant.jar" />
<pathelement location="${ant.jarPath}/ant-contrib-0.3.jar" />
</path>
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath refid="ant.classpath" />
</taskdef>
And in your build property file:
ant.jarPath=D:/antjars
And place ant.jar and ant-contrib-0.3.jar in directory:D:/antjars
Check you have read permissions for the ant-contrib jar file.
In our case after copying the file with another user it did not, giving the same error message.

script to execute the eclipse PDE Tools > Build site

i want to write a script to do the Build site of plugin Update site site.xml?
i could not find a way to do this?
i found very easy to build a plugin feature. I can automatically creat the ant file build.xml via eclipse but i could not find the same for the update site.xml
thank you all
stefania
Are you trying to build an Eclipse plugin from Ant? You want to use the Ant4Eclipse external add-on for Ant. It lets you build the run-configurations you've made in Eclipse (right click>run as>...) from your .project file. You can download it here and there is a tutorial here.
I attempted to do what you're asking at a previous job without using Ant4Eclipse, I don't remember how I got it working, but I do remember it being extremely difficult.
Edit: you can build an Eclipse update site from the command line, which can be run from Ant. There is some [possibly out of date] documentation here, but I found you a sample from an Apache projects build.xml:
<target name="build-site" depends="init">
<copy todir="target/eclipse-update-site/web" preservelastmodified="true">
<fileset dir="web"/>
</copy>
<copy todir="target/eclipse-update-site" file="index.html" preservelastmodified="true"/>
<copy todir="target/eclipse-update-site" file="site.xml" preservelastmodified="true"/>
<!-- copy all the features to the target -->
<copy todir="target/eclipse-update-site/features" preservelastmodified="true" >
<fileset dir="features"/>
</copy>
<!-- see http://wiki.eclipse.org/Update_Site_Optimization -->
<java jar="${eclipse.home}/plugins/org.eclipse.equinox.launcher.jar" fork="true" failonerror="true"
maxmemory="256m">
<arg line="-application org.eclipse.update.core.siteOptimizer"/>
<arg line="-digestBuilder -digestOutputDir=target/eclipse-update-site"/>
<arg line="-siteXML=target/eclipse-update-site/site.xml"/>
</java>

How can I automate (script) creating a war file in eclipse?

It's 5 button clicks to get eclipse to create a deployable war file for my eclipse project, I figure there's probably some eclipse command line option to do the same thing, so I can just write it into a script, but I'm not seeing it.
Use the Ant war task, set up a relevant build file and you can just hit the "external tools" button to execute it.
You could also setup a Maven build for your web project. Typing mvn package from the command line would then build the project for you.
For integration between Maven and Eclipse, see m2Eclipse and Maven Eclipse Plugin.
I cannot say anything about the WAR packaging itself, sorry.
But as I wrote in
How do I automatically export a WAR after Java build in Eclipse? : If you can describe the WAR packaging with an Ant script, you can have that Ant script being executed automatically after each change to your project. Use Project->Properties->Builders->Add->Ant Builder. Give that builder you custom Ant script and it will automatically be executed after the "normal" builders of your project.
You can even specify in the settings of the builder, if it shall only react on changes to specific files and so on.
The Ant builder is kind of a Swiss army knife for anything you want to automate in the project build without having to use the big tools like maven.
This Ant script should work for standard Dynamic Web Project structure of project:
Create Ant build.xml with replacing of two properties at begining:
<?xml version="1.0" encoding="UTF-8"?>
<project name="Deploy From Eclipse to JBoss" basedir="." default="deploy">
<!-- This replace with yours project name and JBoss location: -->
<property name="warfile" value="MyProject"/>
<property name="deploy" value="/home/honza/jboss-as-7.1.1.Final/standalone/deployments"/>
<target name="create">
<war destfile="${warfile}.war" webxml="WebContent/WEB-INF/web.xml" update="true">
<classes dir="build\classes"/>
<fileset dir="WebContent">
<exclude name="WEB-INF/web.xml"/>
</fileset>
</war>
</target>
<target name="copy">
<copy todir="${deploy}" overwrite="true">
<fileset dir=".">
<include name="${warfile}.war"/>
</fileset>
</copy>
</target>
<target name="clear">
<delete includeemptydirs="true">
<fileset dir="${deploy}" defaultexcludes="false">
<include name="${warfile}.*/**" />
</fileset>
</delete>
</target>
<target name="deploy">
<antcall target="create"/>
<antcall target="clear"/>
<antcall target="copy"/>
</target>
</project>
Now should command "ant" do WAR creation and copy them to the JBoss. JBoss automatically deploys wars which finds in deployment directory.
For automatic run after build (Project - Build) add this Buildfile here:
MyProject - Properties - New - Ant builder
