Question

I am trying to get ant4eclipse to work and I have used ant a bit, but not much above a simple scripting language. We have multiple source folders in our Eclipse projects so the example in the ant4eclipse documentation needs adapting:

Currently I have the following:

<target name='build'>    <!-- resolve the eclipse output location -->   <getOutputpath property='classes.dir' workspace='${workspace}' projectName='${project.name}' />    <!-- init output location -->   <delete dir='${classes.dir}' />   <mkdir dir='${classes.dir}' />    <!-- resolve the eclipse source location -->   <getSourcepath pathId='source.path' project='.' allowMultipleFolders='true'/>    <!-- read the eclipse classpath -->   <getEclipseClasspath pathId='build.classpath'                            workspace='${workspace}' projectName='${project.name}' />    <!-- compile -->   <javac destdir='${classes.dir}' classpathref='build.classpath' verbose='false' encoding='iso-8859-1'>     <src refid='source.path' />     </javac>    <!-- copy resources from src to bin -->   <copy todir='${classes.dir}' preservelastmodified='true'>     <fileset refid='source.path'>         <include name='**/*'/>         <!--         patternset refid='not.java.files'/>         -->     </fileset>   </copy> </target> 

The task runs successfully, but I cannot get the to work – it is supposed to copy all non-java files over too to emulate the behaviour of eclipse.

So, I have a pathId named source.path which contains multiple directories, which I somehow needs to massage into something the copy-task like. I have tried nesting which is not valid, and some other wild guesses.

How can I do this – thanks in advance.

You could use the foreach task from the ant-contrib library:

<target name='build'>     ...      <!-- copy resources from src to bin -->     <foreach target='copy.resources' param='resource.dir'>         <path refid='source.path'/>     </foreach> </target>  <target name='copy.resources'>     <copy todir='${classes.dir}' preservelastmodified='true'>         <fileset dir='${resource.dir}' exclude='**/*.java'>     </copy> </target> 

If your source.path contains file paths as well then you could the if task (also from ant-contrib) to prevent attempting to copy files for a file path, e.g.

<target name='copy.resources'>     <if>         <available file='${classes.dir}' type='dir'/>         <then>             <copy todir='${classes.dir}' preservelastmodified='true'>                 <fileset dir='${resource.dir}' exclude='**/*.java'>             </copy>         </then>     </if> </target>
