Question

I have the following code for grepping an xml file repo, in ant :

<echo message="Now checking xml test results for errors"    />
        <exec executable="grep" error="/dev/null">
            <arg value="-r" />
            <arg value="-m" />
            <arg value="1" />
            <arg value="-rl" />
            <arg value="errors=\&quot;[1-9]\&quot;" /> 
            <arg value="${reports.dir}" />
        </exec>
    <fail if="junit.failed" message="FAILING - unit tests failed." />

Im trying to replace :

   <arg value="errors=\&quot;[1-9]\&quot;" /> 

with something along the lines of :

   <arg value="errors|failures=\&quot;[1-9]\&quot;" /> 

So that both errors AND failures will be caught. How can I encode the grep correctly in my Ant XML to reflect this ? "**grep -r -m 1 -rl errors|failures=\"[1-9]\" ../reports/**" does not do the trick ( it results in a syntax issue, breaking the standard grep parser i guess )…

This is a guess, but you could try something along the lines of:

<arg value="-e" />
<arg value="errors=\&quot;[1-9]\&quot;" />
<arg value="-e" />
<arg value="failures=\&quot;[1-9]\&quot;" />

From man grep:

   -e PATTERN, --regexp=PATTERN
          Use PATTERN as the pattern; useful to protect patterns beginning with -.
