Maven jmeter plugin: SAXParseException: Content is not allowed in prolog

Question

I have something like this in my jmx file of jmeter:

<stringProp name="SoapSampler.URL_DATA">http://192.168.0.1:8080/abc/Service</stringProp>

I'm using jmeter maven plugin to get the performance test result when doing the maven build. It's working perfectly.

Now I changed that to a user defined variable in jmeter and try to run that. I get the following error:

"SAXParseException: Content is not allowed in prolog"

Changes in jmx file:

      <elementProp name="server" elementType="Argument">
        <stringProp name="Argument.name">server</stringProp>
        <stringProp name="Argument.value">http://192.168.0.1:8080</stringProp>
        <stringProp name="Argument.metadata">=</stringProp>
      </elementProp>


<stringProp name="SoapSampler.URL_DATA">${server}/abc/Service</stringProp>

However the modified changes works perfectly if executed directly from jmeter GUI. Fails only when executed during maven build.

Here is my pom.xml:

Make sure jmeter.save.saveservice.output_format=xml and Uncomment below lines from your jmeter.properties file (inside bin folder of jmeter installation folder):

jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.data_type=true
jmeter.save.saveservice.label=true
jmeter.save.saveservice.response_code=true
jmeter.save.saveservice.successful=true
jmeter.save.saveservice.thread_name=true
