Mule / Maven Error: Invalid content was found starting with element 'dw:transform-message'

I'm trying to run a project with Maven, using a simple test class, however the test is erroring out (not failing!) with the message:

Test set: com.mycompany.myproject.testApiResponseNotNullTestCase

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 4.423 sec <<< FAILURE! - in com.mycompany.myproject.testApiResponseNotNullTestCase clientTestCase(com.mycompany.myproject.testApiResponseNotNullTestCase) Time elapsed: 3.084 sec <<< ERROR! org.mule.api.config.ConfigurationException: Line 34 in XML document from URL [file:/C:/Users/myuser/Documents/.../dev/Mule%20Workspaces/myproject/myproject/target/test-classes/myproject.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 34; columnNumber: 111; cvc-complex-type.2.4.a: Invalid content was found starting with element 'dw:transform-message'. One of '{"http://www.mulesoft.org/schema/mule/core":abstract-message-processor, "http://www.mulesoft.org/schema/mule/core":abstract-outbound-endpoint, "http://www.mulesoft.org/schema/mule/core":abstract-mixed-content-message-processor, "http://www.mulesoft.org/schema/mule/core":response, "http://www.mulesoft.org/schema/mule/core":legacy-abstract-exception-strategy, "http://www.mulesoft.org/schema/mule/core":abstract-message-info-mapping}' is expected. (org.mule.api.lifecycle.InitialisationException) Caused by: org.mule.api.lifecycle.InitialisationException: Line 34 in XML document from URL [file:/C:/Users/myuser/Documents/.../dev/Mule%20Workspaces/myproject/myproject/target/test-classes/myproject.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 34; columnNumber: 111; cvc-complex-type.2.4.a: Invalid content was found starting with element 'dw:transform-message'.

I have already tried to fix this by adding the following to my pom.xml

<dependency>
   <groupId>com.mulesoft.weave</groupId>
   <artifactId>mule-plugin-weave</artifactId>
   <version>4.0.0-M4</version>
</dependency>

It seems odd (or maybe exactly as expected!?) that all the other items mentioned after "expected" appear in the schema and dw:transform-message doesn't... but this is the XML generated by Anypoint Studio AFAIK.

can you share the myProject.xml from C:/Users/myuser/Documents/.../dev/Mule%20Workspaces/myproject/myproject/target/test-classes/myproject.xml as well. – Naman

You have to add the exact version that matches your Mule Runtime version. If you version is between 3.7.0 and 3.8.1 you need to add:

<dependency>
        <groupId>com.mulesoft.weave</groupId>
        <artifactId>mule-plugin-weave_2.11</artifactId>
        <version>${mule-version}</version>
</dependency>

If it is greater than 3.8.1 and less than 4:

<dependency>
        <groupId>com.mulesoft.weave</groupId>
        <artifactId>mule-plugin-weave</artifactId>
        <version>${mule-version}</version>
</dependency>

For 4.0.0+ you should not add anything.

You must not add different versions than your runtime version. You are not upgrading DataWeave doing that, it will cause undefined and unsupported behavior.

org/xml/sax/SAXParseException.html basically means that there is a missing information in an XML document of your project.

This exception may include information for locating the error in the original XML document, as if it came from a Locator object. Note that although the application will receive a SAXParseException as the argument to the handlers in the ErrorHandler interface, the application is not actually required to throw the exception; instead, it can simply read the information in it and take a different action

And the error stacktrace reads it clearly that in your case its

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'dw:transform-message'

which needs to be fixed at

Line 34 in XML document from URL [file:/C:/Users/myuser/Documents/.../dev/Mule%20Workspaces/myproject/myproject/target/test-classes/myproject.xml]

Add this dependency in your pom

 <dependency>
        <groupId>com.mulesoft.weave</groupId>
        <artifactId>mule-plugin-weave_2.11</artifactId>
        <version>${mule-version}</version>
</dependency>
