Question

Hi,
I try to use FlexUnit 4 to test an air application. I use Maven antrun plugin to compile and run test
code since flex-mojos do not support FlexUnit 4 yet.
My antrun plugin is as follows,
           <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-antrun-plugin</artifactId>
                <version>1.3</version>

                            <tasks>
                                <!-- You can set this directly so mxmlc will work correctly, or set FLEX_HOME as an environment variable and use as below -->
                                <!--property name="FLEX_HOME" location="${env.FLEX_HOME}"/-->
                                <property name="FLEX_HOME" value="${flex.home}"/>
                                <taskdef resource="flexTasks.tasks"/>

                        <version>4.0.0</version>
                    </dependency>
                </dependencies>
            </plugin>
TestRunner.swf is built at target/test-class and I also have TestRunner-app.xml in the same directory where I have
        <content>TestRunner</content>
The problem is that when I try to run a test, I keep getting the following error
[exec] initial content not found
I really appreciate if someone could shred some light on this problem.
Thanks,
John

Hi Brian,
Thanks for your reply!
I've tried building with every version of Ant and FlexUnit I could find, including the latest beta... same problem every time. Though I haven't tried using a different Flex SDK - my project uses 3.2.0. Could that be causing problems? All the FlexUnit versions I can find are for 3.5 or later.
Below is the full console output from my build script (using the flexunit task rather than exec). As for the descriptor file, if you mean the one created by the FlexUnit task, I'm afraid I have nothing to post... since the error is that the task isn't able to create it in the first place. (Or if it is being created, it sure isn't anywhere I can find it - see below for screenshot of project contents.) I can post the descriptor I wrote myself if that will be of any use - just let me know.
Thank you so much for your help!
