I'm trying to use properties to control the processing within my
script. I have several conditions that I want to test and based on
them to stop further processing.
I think my problem lies with the not-set condition and how to handle
this. I don't see anything in the documentation that indicates how
<istrue> and <isfalse> should report an unset value, and I'm assuming
isset returns true if set, but what does it return if not set?
So my big problem seems to be around using <available> to test if a
file exists, so I have that set to true by default with
<available property='have.book' file='foo.txt'/>
Then I test with the condition:
<condition property='continue-processing'>
<or>
<isset property='${no.work}/>
<isset property="${Missing.File.Present}"/>
<not>
<istrue property="$have.book"/>
</not>
</or>
</condition>
So the first 2 properties go true if I want to stop, so I'm thinking
that isset works here, have.book is really a reverse condition. If
its set, I don't want to stop processing, so I have tires istrue and
isset inside the not to try and make it false and that doesn't seem
to be working.
Can anyone spot my logic probelm?
I'm using ant1.5 and can't easily change to something more current as
there are a bunch of ant extensions that were created that I don''t
have access to.
