Maven Xjc/Jaxb Plugin cannot parse simple Xsd file

I'm using the org.jvnet plugin and trying to convert an xsd file into a Java Jaxb-annotated object for use in marshalling and unmarshalling. However, there's an error when trying to compile a simple Xsd file for use.

I think there is a simple syntax error I am making, a second look would be really appreciated. If there's any more details I should provide please let me know. All relevant files and messages are included below.

Error message:

[ERROR] Error while parsing schema(s).Location [ file:/C:/.../project/asdfasdf/src/main/resources/RandomObjectSchema.
xsd{6,46}].

org.xml.sax.SAXParseException; systemId:
  file:/C:/.../project/asdfasdf/src/main/resources/RandomObjectSchema.xsd;
    lineNumber: 6; columnNumber: 46; src-resolve.4.2: Error resolving component 'xsd:int'.
    It was detected that 'xsd:int' is in namespace 'http://www.w3c.org/2001/XMLSchema',
    but components from this namespace are not referenceable from schema document
    'file:/C:/.../project/asdfasdf/src/main/resources/RandomObjectSchema.xsd'.
    If this is the incorrect namespace, perhaps the prefix of 'xsd:int' needs to be changed.
    If this is the correct namespace, then an appropriate 'import' tag should be added to 
    'file:/C:/.../project/asdfasdf/src/main/resources/RandomObjectSchema.xsd'.

You have a mistake in your xsd namespace.

You have:

http://www.w3c.org/2001/XMLSchema

It should be:

http://www.w3.org/2001/XMLSchema

(www.w3c.org vs. www.w3.org)

The error log is quite verbose about it:

[ERROR] s4s-elt-schema-ns: The namespace of element 'schema' must be from the schema namespace, 'http://www.w3.org/2001/XMLSchema'.
  line 2 of file:/.../test.xsd
