How can I have my ant task pass or fail based on the results of a jar it runs?

问题

I'm running CrossCheck (browserless js unit testing) as part of an ant script. I'd like ant to report failure if the CrossCheck tests fail. Here's the relevant bit from the build.xml

<target name="test" depends="concat">
    <java jar="src/test/lib/crosscheck.jar" fork="true">
        <arg value="src/test/webapp/js/"/>
    </java>

And an example of CrossCheck's failure messaging:

Can ant get at the results of the CrossCheck test (perhaps Java Result: 1 gets passed back to ant?) and succeed or fail based on that?

回答1:

Assuming that CrossCheck returns a non-zero return code on a error you could add the failonerror attribute to the java task:

<target name="test" depends="concat">
    <java jar="src/test/lib/crosscheck.jar" fork="true" failonerror="true">
        <arg value="src/test/webapp/js/"/>
    </java>

See the documentation on the Ant java task.

回答2:

You can use the 'failonerror' attribute of the 'java' task.

failonerror Stop the buildprocess if the command exits with a returncode other than 0. Default is "false" (see note)

Check the Ant manual here.
