With the standard ANT tasks you can not handle a 'failing' build.
Of course that's why the authors of the <exec> task provided the 'failonerror'
attribute. Instead of setting it to 'true' (which results in the buildscript
stopping) how about setting it to 'false' and doing the following
<target name="foo" depends="do_exec, success_only, failure_only, after_exec">
</target>
<target name="do_exec">
<property name="success_code" value="0"/>
<exec dir="..." executable="..." resultproperty="result_code"/>
<condition property="exec_succeeded">
<equals arg1="${result_code}" arg2="${success_code}"/>
</condition>
</target>
<target name="success_only" if="exec_succeeded">
...
</target>
<target name="failure_only" unless="exec_succeeded">
....
</target>
<target name="after_exec">
<text2xml src="..." destfile="..."/>
</target>
Now...I have nothing against <trycatch>, I have used it before and it has its
place...but you may want to try using the 'resultproperty' attribute since it
is available

Subject: "post failure tasks" for failing targets
For a cruisecontrol set up we have a task called text2xml. So for
text2xml to do its magic it needs to run :-)
This is problematic for something like:
<target name="foo" depends="">
<exec dir="${binaries.dir}"
executable="${binaries.dir}/${exampleGame.execName}"
output="${compileOptions.logDir}/${exampleGame.log}.log"
failonerror="true">
<arg line="${commandLineParams}"/>
</exec>
<text2xml srcfile = "${compileOptions.logDir}/${exampleGame.log}.log"
destfile = "${compileOptions.logDir}/${exampleGame.log}_log.xml"
element = "${compileOptions.projectName}"
attribute = "name"
value = "${exampleGame.log}"
/>
</target>
So the exec fires off and then it has an error so the failonerror
aborts the target and returns!
This is more generally formed as: How do you do "post failure tasks"
for failing targets when the various exec type tasks return from a
failonerror="true" ?
Is there some way to register a "do after this fails" delegate that I
am missing?
From another thread I saw the trycatch
(http://ant-contrib.sourceforge.net/tasks/tasks/trycatch.html). Is
that the standard way of doing the above?
so if you have:
<target name="a" depends="b,c,d,e,f,g,h,i,j,k,l, taskToRunLast">
You would do something like:
<target name="aDoIt" depends="b,c,d,e,f,g,h,i,j,k,l">
<target name="a">
<trycatch property="foo" reference="bar">
<try>
<antcall target="aDoIt" />
</try>
<catch>
<echo></echo>
</catch>
<finally>
<antcall target="taskToRunLast" />
</finally>
</trycatch>
</target>
And then for each depends that also has some "post failure task" then
slap in a trycatch there also?
Seems to work pretty well in my quick test case. Is this the way to go? :-)
