Ant doesn't truly build

I have an ant script that does and hourly build. I want to do a
fresh, complete build every time, so I delete all .class files before
I do a checkout from cvs. The problem is when it comes to the compile
target. It doesn't seem to recognize packages that don't have at
least one .class file as a package, because when I try to import a
package from whatever .java file is trying to be compiled at that
moment, I get a compile error "package doesn't exist" even though the
.java files are there(it just won't compile them). I have tried using
javamake, but get the same results although it's supposed to do
dependency checking.

I know there must be some tool that does this sort of dependency
checking, because I can compile this way in NetBeans. Does someone
know of a way to do this?

how about posting the target that does the build for you. Plus all the
properties you have in the script.

I do the same thing as you, and i have around 10 packages. I delete the
entire build directory, recreate it, and then run the compile target. It
works everytime.

Here is my build script;


<project name="demo1" default="make" basedir="." >


<property name="src" value="src"/>
<property name="src.images" value="src/images"/>
<property name="dist" value="dist"/>
<property name="dist.class" value="${dist}/WEB-INF/classes"/>
<property name="dist.lib" value="${dist}/WEB-INF/lib"/>
<property name="dist.images" value="${dist}/images"/>
<property name="docs" value="docs" />


<path id="local_cp" >
<pathelement path="${classpath}" />
<fileset dir="${dist.lib}" >
<include name ="**/*.jar" />
</fileset >
</path>


<target name="clean"
description="removes all the class files from the classes
directory." >


<delete dir="${dist.class}" />
<mkdir dir="${dist.class}" />


<delete dir="${dist.images}" />
<mkdir dir="${dist.images}" />
</target>


<target name="make"
description="makes all the classes in the WebInf classes
directory.">

<mkdir dir="${dist}" />
<mkdir dir="${dist.class}" />
<mkdir dir="${dist.images}" />


<javac srcdir="${src}"
destdir="${dist.class}"
debug="true" >
<classpath location="${src}" />
<classpath refid="local_cp" />
</javac>

<copy todir="${dist.class}" includeEmptyDirs="true">
<fileset dir="${src}">
<include name="**/*.jwc"/>
<include name="**/*.application"/>
<include name="**/*.html"/>
<include name="**/*.page"/>
<include name="**/*.hbm.xml"/>
<include name="**/*.properties"/>
</fileset>
</copy>

<copy todir="${dist.images}" includeEmptyDirs="true">
<fileset dir="${src.images}">
<include name="**/*.jpg"/>
<include name="**/*.gif"/>
</fileset>
</copy>

</target

Please, someone take a stab at it. Doesn't seem to work for me.

You said that you delete the class files, but do you leave the empty
directories? I have seen the "package does not exist" with empty directories
(source directories though). The error is reported by javac.

Maybe that's your problem. I don't have time to read your ant file, but make
sure to delete the whole directory under which the packages reside.

I tried that as well, but ant still can't recognize the package with
only .java files in it. Also J, on your script, you are deleting only
the class files from your dest directory, whereas I am trying to
delete all class files from my src directory and recompile them there.
