How to stop ant execution if one target fails
I'm using ant to build my project. When running ant from the command line, I'm passing in multiple targets. For example:
ant -verbose clean build jar findbugs pmd
Ant will execute the targets clean, build, jar, findbugs, and pmd in that order.
My problem is that if one of the targets fail, ant continues with the next target. I would like it to stop execution if one fails.
For example, if the "jar" target fails, ant should not call the findbugs and pmd targets.
Any help is appreciated.

AW: How to stop ant execution if one target fails
Posted by Ja...@rzf.fin-nrw.de.
A build fails, if a BuildException occurs during task execution.
This is the case on some tasks when they "find" some mistakes like <javac> and invalid java source.
An other example is <junit> with failing tests, but here you can specify whether the build should fail or failing test should just be reporting using <junit haltonfailure|haltonerror>.
With <fail> you can directly throw a BE and the build will halt.
I am not sure, but I think you can "overwrite" this behaviour using -k(eep-going).
ant -h
ant [options] [target [target2 [target3] ...]]
Options:
-keep-going, -k execute all targets that do not depend
on failed target(s)
Here Ant would report the failing tasks/targets and try the next target which dont rely on a prior successful target.
It is not unusual to keep the failure-status in a property and react on that.
<target name="test" depends="compile">
<junit failureproperty="junit.failed"
<target name="checkstyle">
<cs:checkstyle failOnViolation="false" failureProperty="checkstyle.failed"
<target name="pmd">
<pmd:pmd failuresPropertyName="pmd.failed"
<target name="findbugs">
<fb:findbugs errorProperty="findbugs.failed"
<target name="metrics" depends="-checkmetrics" unless="metrics.failed">
<echo>All metrics passed</echo>
</target>
<target name="-checkmetrics" depends="test,checkstyle,pmd,findbugs">
<condition property="metrics.failed"><or>
<isset property="junit.failed"/>
<isset property="pmd.failed"/>
<isset property="findbugs.failed"/>
<isset property="checkstyle.failed"/>
</or></condition>
</target>

Re: How to stop ant execution if one target fails
Posted by John5342 <jo...@googlemail.com>.
If the names of the targets are indeed what they do then most of them should
probably always be done in a particular order in which case make each one
depend on the next similar to the following.
<target name="jar" depends="build" ....>
....
</target>
Then if you were to run "ant jar" then build will be automatically run
before jar and if build fails then jar will not be run. You should be able
to do this for most of your targets and then all required targets will
always be automatically run and you only call the target you actually need.
Hope that helps you.
John.

You may want to use something like this.... <fail unless="workspace"
message="The workspace property needs to be set!"/>

Subject: How to stop ant execution if one target fails
I'm using ant to build my project. When running ant from the command
line, I'm passing in multiple targets. For example:
ant -verbose clean build jar findbugs pmd
Ant will execute the targets clean, build, jar, findbugs, and pmd in
that order.
My problem is that if one of the targets fail, ant continues with the
next target. I would like it to stop execution if one fails.
For example, if the "jar" target fails, ant should not call the findbugs
and pmd targets.
Any help is appreciated.
