This is insane! Is there no way to preserve information set in an antcall? I
tried to change strategy a little and do the following:
<project default="invalid">
<!-- Import the properties_common.xml file -->
<import file="properties.xml" />
<import file="includes.xml" />
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<taskdef name="unset" classname="ise.antelope.tasks.Unset"/>
<target name="invalid">
<property name="labelset" value="false"/>
<antcall target="dotest1" inheritall="true" />
<echo>before going to dotest2 labelset = ${labelset}</echo>
<antcall target="dotest2" inheritall="true" />
</target>
<target name="dotest1" depends="setvalue">
<echo message="in test1 and value of labelset is: ${labelset}"/>
</target>
<target name="dotest2" depends="setvalue">
<echo message="in test2"/>
<echo message="value of labelset is: ${labelset}"/>
</target>
<target name="setvalue">
<if>
<equals arg1="${labelset}" arg2="false" />
<then>
<echo>Before setting the value, labelset = ${labelset}</echo>
<echo>setting the value to true</echo>
<unset name="labelset"/>
<property name="labelset" value="true" />
<echo>labelset = ${labelset}</echo>
</then>
</if>
</target>
</project>
Same results:
Buildfile: testthrow.xml
invalid:
setvalue:
[echo] Before setting the value, labelset = false
[echo] setting the value to true
[echo] labelset = true
dotest1:
[echo] in test1 and value of labelset is: true
[echo] before going to dotest2 labelset = false
setvalue:
[echo] Before setting the value, labelset = false
[echo] setting the value to true
[echo] labelset = true
dotest2:
[echo] in test2
[echo] value of labelset is: true
BUILD SUCCESSFUL
It loses the setting that happened in setvalue... Anybody?????

I just threw this out because I couldn't get anything to work. Reviving
because I can't accept failure. Budd, your repro wasn't doing what I wanted,
but I didn't realize why until now. The reson you went into test1 was because
you didn't put an unless clause on it. Put the unless clause on it and you
wouldn't go into it. As soon as you instantiate the var, you won't go into any
of the targets for the var. I want to go into my target once and only once.
Consider the following example:
<project default="invalid">
<!-- Import the properties_common.xml file -->
<import file="properties.xml" />
<import file="includes.xml" />
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<taskdef name="unset" classname="ise.antelope.tasks.Unset"/>
<target name="invalid">
<var name="testit" value=""/>
<antcall target="dotest1" inheritall="true" />
<antcall target="dotest2" inheritall="true" />
</target>
<target name="dotest1" depends="setvalue">
<echo message="in test1 and value of testit is: ${testit}"/>
</target>
<target name="dotest2" depends="setvalue">
<echo message="in test2"/>
<echo message="value of testit is: ${testit}"/>
</target>
<target name="setvalue" unless="testit">
<echo>setting the value to true</echo>
<var name="testit" value="true" />
<echo>testit = ${testit}</echo>
</target>
</project>
It won't go into setvalue ever because testit is already instantiated. I want
it to go in once. Anyone able to help me on this?
Thanks,
Eric

Ahhh, you're using var instead of property. I missed that before. Since you
instantiate it first, the scope remains over the antcalls. Beautiful, thanks
Budd!

Eric,
Okay try this one.

</target>
<target name="setvalue">

<var name="testit" value="1.2.3.4" />
<echo>testit = ${testit}</echo>

Sorry Budd, it looks like I wasn't clear on one aspect of this. The value of
this property must be set inside of the first target called. In reality, the
first target called has a depends target that may set this property. Based on
whether it sets that property, we may or may not want to come back to that
target again. So a more valid repro would be:
<project name="test" default="testIt">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<target name="testIt">
<antcall target="test1" inheritall="true" />
<echo message="back out to main target, label is: ${label}"/>
<antcall target="test2" inheritall="true" />
</target>
<target name="test1" depends="setLabel" >
<echo message="in test1 and value of label is: ${label}"/>
</target>
<target name="test2" depends="setLabel">
<echo message="in test2"/>
<echo message="value of label is: ${label}"/>
</target>
<target name="setLabel" unless="label">
<property name="label" value="1.2.3.4"/>
<echo message="I'm creating a label here..."/>
</target>
</project>
And the results from running this are:
Buildfile: test.xml
testIt:
setLabel:
[echo] I'm creating a label here...
test1:
[echo] in test1 and value of label is: 1.2.3.4
[echo] back out to main target, label is: ${label}
setLabel:
[echo] I'm creating a label here...
test2:
[echo] in test2
[echo] value of label is: 1.2.3.4
BUILD SUCCESSFUL
Total time: 0 seconds
You see that it attempts to create the label twice which will fail in my real
application. I think what I need to do instead is:
<project name="test" default="testIt">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<target name="testIt" depends="setLabel">
<antcall target="test1" inheritall="true" />
<antcall target="test2" inheritall="true" />
</target>
<target name="test1">
<echo message="in test1 and value of label is: ${label}"/>
</target>
<target name="test2">
<echo message="in test2"/>
<echo message="value of label is: ${label}"/>
</target>
<target name="setLabel">
<property name="label" value="1.2.3.4"/>
<echo message="I'm creating a label here..."/>
</target>
</project>
In my real world application, that will take some rewriting, but simple is
good... Thanks for looking at my spaghetti (mmmmmm, meatballs)!
Thanks,
Eric

Hi! I've found that my unless= is somewhat useless when using <antcall>.
Here's a repro for what I'm trying to do:
<project name="test" default="testIt">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<target name="testIt">
<antcall target="test1" inheritall="true" />
<antcall target="test2" inheritall="true" />
</target>
<target name="test1">
<property name="testit" value="true"/>
<echo message="in test1 and value of testit is: ${testit}"/>
</target>
<target name="test2" unless="testit">
<echo message="in test2"/>
<echo message="value of testit is: ${testit}"/>
</target>
</project>
And the results that I'm sure you anticipate as you understand how antcall
works:
[me@myMachine]$ ant -f test.xml
Buildfile: test.xml
testIt:
test1:
[echo] in test1 and value of testit is: true
test2:
[echo] in test2
[echo] value of testit is: ${testit} BUILD SUCCESSFUL Total time: 0
seconds
My actual antcall is in a for loop using a list to call targets that start with
the same word, like so:
<for list="${build.apps} param="app">
<sequential>
<antcall target="build@{app}"/>
</sequential>
</for>
Can anyone give me a better methodology for achieving the results I'm after?
Thanks,
Eric
