Hi, all.
I want to do a simple isset test on three critical properties, using ANT
1.5b1. This should be pretty straightforward with the isset option on
condition.
<target name="check-properties" description="Checks whether all needed
properties have been defined">
<condition property="missing.properties">
<not>
<and>
<isset property="${allproject.dir}"/>
<isset property="${project.name}"/>
<isset property="${project.work.dir}"/>
</and>
</not>
</condition>
</target>
<!-- Gives intructions on how to proceed if check is not succesful -->
<target name="help-properties" depends="check-properties"
if="missing.properties">
<echo message="Not all needed properties are set."/>
<echo message=" allproject.dir='${allproject.dir}' - The base
directory from which all projects descend, and into which cvs puts the
individual projects"/>
<echo message=" project.name='${project.name}' - The name of the
project"/>
<echo message=" project.work.dir='${project.work.dir}' - The base
directory where a local build file would live, and where classes are
generated"/>
<fail message="Not all needed properties are set."/>
</target>
Thus, the body of help-properties will only execute if
missing.properties is set, and that will be tested after
check-properties is run.
if all three properties have values, then the AND is true. The NOT
reverses that, so the only time missing.properties will be set is if one
is missing.
The output:
help-properties:
[echo] Not all needed properties are set.
[echo]
allproject.dir='/Users/work/Documents/coding/isis/source/genetrove/persistence/
cluster_genetrove/../../..' - The base directory from which all projects
descend, and into which cvs puts the individual projects
[echo] project.name='cluster_genetrove' - The base directory from
which all projects descend, and into which cvs puts the individual
projects
[echo]
project.buildfile.dir='/Users/work/Documents/coding/isis/source/genetrove/
persistence/cluster_genetrove' - The base directory from which all
projects descend, and into which cvs puts the individual projects
So, all three look set. What am I missing?
