[JVM] Passing Ant Value to Java

[theposob]

I am currently running several tests via cucumber-jvm, and I am kicking them off via an ant script. I am passing values to the ant script via command line at run, which are then overriding my Cucumber.Options values. This is working fantastic, and allows me to select different feature files, and different scenarios with specific tags on the fly. My question is, can my actual java code access these values from the ant script. Anywhere in the javacode would be acceptable, but ideally my @Before method could access these values to properly setup my testing environment based on the tests being run. Thanks in advance for the support!

You mean you're defining JVM system properties on the command line using -D?

This is really a question about Ant, not Cucumber. Rephrased:

When you say values, what exactly do you mean? JVM system properties? Ant <property> values?

Please see An't docs for the <java> task to learn how to pass JVM system properties to a java program launched from Ant.

If you fork, you have to pass them explicitly, if you don't fork, Ant and Cucumber will run in the same JVM and have access to the same system properties.

Aslak, thanks for the quick response, I'll checkout the ant docs and see what I can get from them. I put in some answer below, just to clarify in case anyone else has this question.

Correct

I mean the target argument values. E.g.: <arg value="${feature}"/>, and <arg value="--tags"/>            <arg value="${tags}"/> 

Please see An't docs for the <java> task to learn how to pass JVM system properties to a java program launched from Ant.

If you fork, you have to pass them explicitly, if you don't fork, Ant and Cucumber will run in the same JVM and have access to the same system properties.

I'm unsure what you mean by forking. Which I'll assume means I am not, just using the base functionality. Thanks for the reference.

Just a quick update, this was much simpler than I thought. 

I have set forked to true, so I had to explicitly set the value. That section of my build.xml file looks something like the below:

      <java classname="cucumber.api.cli.Main" fork="true" failonerror="false" resultproperty="cucumber.exitstatus">

            <classpath refid="classpath"/>

            <arg value="${feature}"/>

            <arg value="--tags"/>

            <arg value="${tags}"/>

            <sysproperty key="tags" value="${tags}"/>

      </java>

Then to access this value, I have something like the below:

@Before //performed before anything is done

public void setup() throws SAXException, IOException {

               System.out.println( "tags: " + System.getProperty( "tags" ) );

         }

Thanks for the pointers on where to look!
