Hi,
I have recently started to use Ant on Eclipse IDE. I am trying to run
a file called HelloWorld located in the jse.core package. The build.xml is
located at:
C:\dev\eclipse\workspace32\jse-core\build.xml
HelloWorld.java and HelloWorld.class is located at:
C:\dev\eclipse\workspace32\jse-core\jse\core
This is how my build.xml looks like:
<project name="project1" default="run" basedir=".">
<target name="init">
<echo> The Java Version is ${ant.java.version} </echo>
</target>
<target name="compile">
<javac srcdir="." destdir="." includes="HelloWorld.java" />
</target>
<target name="run" depends="compile">
<java classname="jse.core.HelloWorld"/>
</target>
</project>
The compilation part works fine, but when the run target is executed, I get the
error message as:
Could not find jse.core.HelloWorld. Make sure you have it in your classpath
I see that java task has a classpath attribute, but I am not sure how to use
it. Please advice.
Thanks.
In your case you compile to the basedir, so the <java>
looks like this:
<java classname="jse.core.HelloWorld" classpath="."/>
Normally, one has a source directory contains
the source files and compiles to a build directory - build, or build/classes
<target name="compile">
<mkdir dir="build/classes"/>
<javac srcdir="src" destdir="build/classes"
debug="yes"/> <!-- need to set debug, otherwise ant
will use -g:none -->
</target>
<target name="run" depends="compile">
<java classname="jse.core.HelloWorld" classpath="build/classes"/>
</target>
<target name="clean">
<delete dir="build"/>
</target>
