[ https://issues.redhat.com/browse/JBMETA-418?page=com.atlassian.jira.plugi... ] Wolfgang Knauf updated JBMETA-418: ---------------------------------- Description: I build a "jboss-web.xml" file referencing jboss-web_14_0.xsd (bundled with WildFly 18), using Eclipse IDE: {noformat} <?xml version="1.0" encoding="UTF-8"?> <jboss-web xmlns="http://www.jboss.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/schema/jbossas/jboss-web_14_0.xsd" version="14.0"> <context-root>MyWebProject</context-root> </jboss-web> {noformat} Eclipse shows validation errors deep in jboss_web_14_0.xsd. Unfortunately, I can not copy from nested validation errors. So I will attach a screenshot and type one of the error lines: sch-props-correct.2: A schema cannot contain two global components with the same name; this schema contains two occurences of 'http://xmlns.jcp.org/xml/ns/javaee,descriptionGroup' The reason seems to be that "jboss-web_14_0.xsd" imports two files: * "web-app_4_0.xsd" which imports "web-common_4_0.xsd" which imports "javaee_7.xsd". * "jboss-common_8_0.xsd" which imports "javaee_8.xsd" This is quite confusing, as the JavaEE8 standard has a lot of XSD files which import "javaee_7.xsd": [JavaEE schemas|https://www.oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/in...] It should work if "jboss-web_14_0.xsd" imports "jboss-common_7_1.xsd" and thus "javaee_7.xsd". I don't see any relevant differences beetween "jboss-common_7_1.xsd" and "jboss-common_8_0.xsd", so this should be possible. was: I build a "jboss-web.xml" file referencing jboss-web_14_0.xsd (bundled with WildFly 18), using Eclipse IDE: {noformat} {{<?xml version="1.0" encoding="UTF-8"?> <jboss-web xmlns="http://www.jboss.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/schema/jbossas/jboss-web_14_0.xsd" version="14.0"> <context-root>MyWebProject</context-root> </jboss-web>}} {noformat} Eclipse shows validation errors deep in jboss_web_14_0.xsd.
