I was reasonably comfortable with Ant a few years ago but haven't
touched it in quite a while so I need a bit of a refresher. I've tried
looking in the manua but it always seems to answer only part of the
question so I thought I'd try here.
Among the things that my Ant script needs to do is write a specific
document. That document has three optional parts, each of which the
person running the script may choose to write or omit. I'm leaning
toward using an Ant form with a checkSelectionProperty for each of the
three optional parts.
The relevant bit of my script is:
=====================================================================================
<!-- Let the user choose to show or hide specific items. -->
<target name="verify_switches" description="Let the user choose which
content to omit.">
<antform title="Choose Information Which Will Not Be Displayed">
<label>Use the checkboxes to control which of the following
content is shown. Choose Abort to cancel the build.</label>
<checkSelectionProperty label="" property="omit.optional.part1"
values="Omit Optional Part 1"/>
<checkSelectionProperty label="" property="omit.optional.part2"
values="Omit Optional Part 2"/>
<checkSelectionProperty label="" property="omit.optional.part3"
values="Omit Optional Part 3"/>
<controlbar>
<button label="Abort" target="abort2" type="cancel"/>
<button label="Ok" type="ok"/>
</controlbar>
</antform>
</target>
<target name="Omit_Optional_Part1" description="Omit optional part 1."
if="omit.optional.part1">
<replaceregexp file="${baz.src}\${baz.pkg}\ResumeConstants.java"
match="^[\s]*public static final boolean
SHOW_OPTIONAL_PART1[\s]*=[\s]*([^;]+);[\s]*$"
replace=" public static final boolean SHOW_OPTIONAL_PART1 =
false;"
byline="true"/>
</target>
<target name="Omit_Optional_Part2" description="Omit optional part 2."
if="omit.optional.part2">
<replaceregexp file="${baz.src}\${baz.pkg}\ResumeConstants.java"
match="^[\s]*public static final boolean
SHOW_OPTIONAL_PART2[\s]*=[\s]*([^;]+);[\s]*$"
replace=" public static final boolean SHOW_OPTIONAL_PART2 =
false;"
byline="true"/>
</target>
<target name="Omit_Optional_Part3" description="Omit optional part 3."
if="omit.optional.part3">
<replaceregexp file="${baz.src}\${baz.pkg}\ResumeConstants.java"
match="^[\s]*public static final boolean
SHOW_OPTIONAL_PART3[\s]*=[\s]*([^;]+);[\s]*$"
replace=" public static final boolean SHOW_OPTIONAL_PART3 =
false;"
byline="true"/>
</target>
<target name="abort2" description="Display a message that the build was
cancelled.">
<fail message="The user chose not to proceed with the build."/>
</target>
=====================================================================================
The "verify_switches" target is part of the "depends" on my 'buildall'
target.
What I'm TRYING to do is get the form to display three separate
checkboxes. Each checkbox identifies a different one of the three
optional parts of the document. The user puts a checkmark beside each of
the optional parts that he wants to OMIT in the document; if he doesn't
put a checkmark beside a given part, that part will be written in the
document. For each checkbox that is checked, a new property is created
Then, the other three targets, Omit_Optional_Part1, Omit_Optional_Part2,
and Omit_Optional_Part3 are supposed to be invoked but ONLY if the
relevant checkbox was checked on the AntForm. The three "omit" targets
simply edit a class containing constants and change the value of one
boolean each from true, the default, to false. In other words, if the
user chooses to omit part 1 from the document, the "Omit_Optional_Part1"
target changes a constant named SHOW_OPTIONAL_PART1 from true to false.
And so on for the other two "optional" targets.
Unfortunately, this code doesn't work. While the AntForm displays just
fine, it doesn't seem to be creating the relevant properties. Or maybe
it is and the "optional" targets just aren't coded correctly. The fact
is that the the "optional" targets sometimes run regardless of the
existence of the properties created in the form and sometimes DON'T run,
even if the property should have been created.
Obviously, I'm doing something wrong but I can't figure it out from the
documentation I've been able to find. AntForm is especially poorly
documented in that it has very few examples and none that illustrate how
to work with checkSelectionProperty.
Can someone kindly tell me what I'm doing wrong?
I am running Ant 1.7.1 in Eclipse 3.5.1 (Galileo). My OS is Windows XP SP2.
