Checking a property with ant
I have tried a few things today and still can't figure this out. I have a
properties file with a setting of say test=successful and I want ant to
check the property test to make sure it is set to successful before going
on. How do I do this?

Betreff: RE: Checking a property with ant
This is a 2 step process. First you need to also create a conditional property based on the value of the property test. Then you can use that conditional property in target elements to conditionalize their execution. For instance
Step 1:
<condition name="conditionOK">
<equals arg1="${test}" arg2="successful"
</condition>
Step 2:
<target name="conditional_target" if=conditionOK>
... your target elements
</target>

Translation:
if ( buildresults == "failed" ) {
buildfailed = true;
}
// otherwise 'buildfailed' is not set
> <target name="buildresults" unless="buildfailed">
> <fail message="Check deploy script for error" />
> </target>
public target buildresults() {
// unless clause
if ( buildfailed != null ) {
return;
}
fail("Check deploy script for error");
}

your condition is right, you check whether your
${buildresults} property (set in a property file or
otherwise) has the value "failed" and if yes the
property ${buildfailed} is set.
but =
<target name="buildresults" unless="buildfailed">
means = run that target unless your ${buildfailed} property
is set, regardless what value it holds
so you need to use =
<target name="buildresults" if="buildfailed">
instead.

This is what I have:
<condition property="buildfailed">
<equals arg1="${buildresults}" arg2="failed"/>
</condition>
<target name="buildresults" unless="buildfailed">
<fail message="Check deploy script for error" />
</target>
If I am understanding this correctly then, the above should reference the
buildresults property that is held in a property file and if it is set to
failed...the script should fail. The issue is that when the buildresults is
set to successful, the build still fails.
Anyone see what I am doing wrong?

therefore in my example the property thats' used
afterwards with target if|unless is set via
condition + equals ... ;-)

> <target name="foo" unless="foo">

so afterwards you're able to react if| unless
that property is set after your gusto

I got failure when
command="find . -maxdepth 1 -name ${reporting.db}.\*\.001 |
wc -l"/>
... the trick is why doesn't 0 -eq 0 is when it has EOL so adding pipe xargs
echo -n resolved this bug
hope this helps test your condition.
<target name="db2-test">
<sshexec host="${reporting.host}" trust="true"
username="${reporting.user}" password="${reporting.password}"
outputproperty="reporting.backup.count" failonerror="true"
command="find . -maxdepth 1 -name ${reporting.db}.\*\.001 |
wc -l | xargs echo -n"/>
<condition property="missing.backup">
<equals arg1="${reporting.backup.count}" arg2="0"/>
</condition>
</target>
<target name="testdb" depends="db2-test" unless="missing.backup">
...
</target>

But dont forget: <target if|unless> checks whether a property with
the given name is set/not-set.
<property name="foo" value="true"/>
<target name="foo" unless="foo">
<echo>I will be executed</echo>
</target>
<property name="bar" value="false"/>
<target name="bar" if="bar">

see manual <condition>, f.e. =
<condition property="allOK">
<equals arg1="${test}" arg2="successful"/>
</condition>
and later on =
<target name="whatever" if="allOK">
...
</target>
or the other way around
<target name="whatever" unless="allOK">
...
</target>
