XML validation errors (incomplete project-based XSD schemas resolution?)

Using STS4 4.6.0 in Eclipse. In #108 project-based XSD schema resolution was implemented. I’m pretty sure I saw this working in other places, but I have a XML file using Spring Integration namespace XML elements for which this resolution seems to (partially) fail. I have Spring Integration 4.3.21 in the classpath (both core and http modules) and snippets like these:

<int:header-enricher
    input-channel="preAuthRequestChannel"
    output-channel="restServiceRequestChannel">
    <int:header name="myHeader"
        expression="someGreatExpression" />
</int:header-enricher>

The above is marked with this error:

cvc-complex-type.3.2.2: Attribute 'expression' is not allowed to appear in element 'int:header'.

Similar errors are given on <int-http:outbound-gateway> attributes like http-method-expression or request-factory. I’m using the unversioned namespaces:

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	default-lazy-init="true"
	xmlns:int-http="http://www.springframework.org/schema/integration/http"
	xmlns:int="http://www.springframework.org/schema/integration"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration.xsd
		http://www.springframework.org/schema/integration/http https://www.springframework.org/schema/integration/http/spring-integration-http.xsd">

If I replace the unversioned XSDs with the versioned (4.3) ones, those errors go away. But I would like to avoid it. The Spring Boot language server log doesn’t show any error/exception. The XML where I have this problem seems to be detected as well as any updates to it:

17:22:07.712 [pool-4-thread-1] INFO  o.s.i.v.boot.app.SpringSymbolIndex - Update document [xml changed]: file:///home/mauro/svn/DCS-SHOP-trunk/shop-commons/src/main/resources/context/myfile-foo.xml

Basic XML code assist for attribute names work (even for those attributes that are marked in red!), as well as further STS4 code assist within <bean> attributes (like class or property).

If I right click on the editor and choose “Validate”, I get “The validation completed with no errors or warnings”, yet I have those errors in the left vertical ruler and attributes are underlined in red.

I tried to:

• restart Eclipse
• clean that project
• close and reopen that project

without success.

Any idea on what is going on?

Thanks a lot @martinlippert! I will watch that new issue when it is available.
