Java source files not part of any package

[Dianne Yumul]

Hello Everyone,

I'm learning to use Ant 1.7.0 as part of Xcode 3.1.2 on Mac OS X  
10.6.  We have a separate directory called Common/ where we keep  
common java source files. These files need to get included, not all at  
the same time though, when compiling our Java applications.  What  
would be the best way to do this?

If I add Common/ to srcdir, it compiles everything inside when I only  
need a one or two.  The FAQ mentions that "If you have Java source  
files that aren't declared to be part of any package, you can still  
use the <javac> task to compile these files correctly - just set the  
srcdir and destdir attributes to the actual directory the source files  
live in and the directory the class files should go into,  
respectively."  But how to do this exactly? Do I need two separate  
javac tasks like the following?

<javac srcdir="../../../Common/src" destdir="../../../Common/bin"  
classpathref="lib.path" debug="on"/>
<javac srcdir="src" destdir="bin" classpathref="lib.path" debug="on"/>

Thank you.

Look at the include / exclude parameter options

Thanks for the suggestion Chris.  I tried using the includes parameter  
and it works.  Here's what it looks like:

<javac destdir="${bin}"  includeAntRuntime="no"  
classpathref="lib.path" debug="${compile.debug}">
        <src path="src"/>
        <src path="../Common"/>
        <include name="AuthWindow.java"/>
        <include name="DateFormatField.java"/>
        <include name="Capacity.java"/>
        <include name="CapacityPrinter.java"/>
</javac>

Here's the directory structure:

/Common/AuthWindow.java
/Common/DateFormatField.java
/Common/Capacity.java
/Common/CapacityPrinter.java
/Edit Capacities/src/Edit_Capacities.java

I was hoping for another (better?) way to do this like it says in the  
FAQ.

Thanks again.

that's not going to help, ant will still compile everything in common/

Two options

* <copy> only the files you need to somewhere (like build/src and
include that in the compile


* use the nested <fileset file> elements in <src> inside javac

<property name="common.dir" location="../../../Common" />

<javac destdir="${build.classes.dir}">
<src>
  <fileset file="${common.dir}/Utils.java" />
  <fileset file="${common.dir}/Arrays.java" />
</src>


Know that Javac will pull in extra java source files if imported, it may
compile more than you expect.

Thank you Steve for the suggestions.  I tried option 2 with the  
following:

<property name="src" location="src"/>
<property name="src.common" location="../../Common">

<javac destdir="${bin}"  includeAntRuntime="no"  
classpathref="lib.path" debug="${compile.debug}">
        <src path="src"/>
        <src>
                <fileset file="${src.common}/AuthWindow.java"/>
        </src>
</javac>

But I get the error /Common/AuthWindow.java is not a directory.

Going back to the manual and some more searching.

Thanks.

Another option would be going back to running javac twice but with the  
includes in the appropriate place:

<javac srcdir="${src.common}" destdir="${bin}" includeAntRuntime="no"
              classpathref="lib.path" debug="${compile.debug}">
        <include name="AuthWindow.java"/>
        <include name="Capacity.java"/>
        <include name="CapacityPrinter.java"/>
        <include name="DateFormatField.java"/>
</javac>
<javac srcdir="${src}" destdir="${bin}"  includeAntRuntime="no"
             classpathref="lib.path" debug="${compile.debug}">
</javac>

This way it compiles only what I need from the Common folder and  
everything from the project's src folder.
Is there a disadvantage to doing it this way?

Thanks.
