Issue with MUnit and Spring Security Schema - spring-security

Question

I have a API-kit project that incorporates spring security basic authentication. The application builds and runs successfully without MUnit tests. When including MUnit tests, it fails to build giving the following:
WARN 2019-07-09 11:21:18,619 [main] org.springframework.beans.factory.xml.XmlBeanDefinitionReader: Ignored XML validation warning
org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.mulesoft.org/schema/mule/spring-security/current/mule-spring-security.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
Running the MUnit tests themselves, all pass.
The flows that implement this security use the following:
<mule-ss:http-security-filter
doc:name="API Secutiry filter"
realm="mule-realm"
securityProviders="delegateSecurityProvider" />
where the security manager is defined as:
<mule-ss:security-manager
name="Spring_Security_Provider"
doc:name="Spring Security Provider">
<mule-ss:delegate-security-provider
name="delegateSecurityProvider"
delegate-ref="authenticationManager" />
</mule-ss:security-manager>
and the authentication manager is defined as:
<spring:beans>
<ss:authentication-manager alias="authenticationManager">
<ss:authentication-provider>
<ss:user-service id="userService">
<ss:user
name="${gov.mt.dphhs.telcor.authentication.user}"
password="${gov.mt.dphhs.telcor.authentication.password}"
authorities="ROLE_ADMIN" />
</ss:user-service>
</ss:authentication-provider>
</ss:authentication-manager>
</spring:beans>
The XML namespaces are as follows:
xmlns:mule-ss="http://www.mulesoft.org/schema/mule/spring-security"
xmlns:ss="http://www.springframework.org/schema/security"
http://www.mulesoft.org/schema/mule/spring-security http://www.mulesoft.org/schema/mule/spring-security/current/mule-spring-security.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd
Additional information:
<mule.version>3.8.0</mule.version>
<mule.tools.version>1.2</mule.tools.version>
<munit.version>1.3.7</munit.version>

Answer 1

Seems you are missing the spring-security module
<dependency>
<groupId>org.mule.modules</groupId>
<artifactId>mule-module-spring-security</artifactId>
<version>${mule.version}</version>
</dependency>
