Eclips and Ant

[Ed Mirsky]

I down loaded eclipse-SDK-3.0.2-win32, and purchased the Eclipse Cookbook, 2004 ISBN: 0-596-00710-8. Example files are at
http://examples.oreilly.com/eclipseckbk/

Chapter 7 �Eclipse and Ant� develops a project called AntProject, which I am unable to get to work. Since the figures in the chapter don�t match the dialogs in Eclipse, I suspect the chapter needs to be updated to match the new Eclipse SDK.

I imported the example from Ch 07, which I downloaded from the Eclipse website, and got the following error message when I ran it:

Buildfile: C:\Documents and Settings\Administrator\Local Settings\Temp\eclipse-SDK-3.0.2-win32\eclipse\workspace\AntProject\build.xml
Initialization:

Total time: 1 second

How should I change the build.xml file below to get the program to work?

<?xml version="1.0" encoding="UTF-8"?>
<project name="AntProject" default="Build" basedir=".">

<property name="build.compiler"
value="org.eclipse.jdt.core.JDTCompilerAdapter" />
<property name="srcDir" location="src" />
<property name="binDir" location="bin" />
<property name="jarDir" location="${binDir}/lib" />
<property name="jarFile" location="${jarDir}/AntProject.jar" />

<target name="Initialization">
<delete dir="${binDir}" />
<delete dir="${jarDir}" />
<mkdir dir="${binDir}" />
<mkdir dir="${jarDir}" />
</target>

<target name="Compilation" depends="Initialization">
<javac srcdir="${srcDir}"
destdir="${binDir}" />
</target>

<target name="Jar" depends="Initialization, Compilation">
<jar destfile="${jarFile}" basedir="${binDir}" />
</target>

<target name="Build" depends="Initialization, Compilation, Jar">
<echo message="Ant is building your project." />
</target>

</project>

Thank you in advance,

Ed,

Not sure if you've resolved your problem or not b/c it's been several days since you posted.

If so, great!

If not, you have two options...

1.) You can comment out the property that sets build.compiler, Ant will then use the JDK that eclipse is running under
2.) If you really want to use that JDTCompilerAdapter, follow these steps:

Click Window, Preferences on the menu bar

Expand the Ant item on the left and click on Runtime

With the Classpath tab selected, click on Ant Home Entries

Click the Add External Jars button

Browse to your eclipse installation (maybe c:\eclipse), then open the Plugins directory

Find the directory org.eclipse.jdt.core_3.0.1 and open it

Select both jdtCompilerAdapter.jar and jdtcore.jar and click Open

Click OK and your build script should now run

Good luck!
