I:

(1) Error reporting: org.xml.sax.saxparseexception; lineNumber: 18; columnNumber: 70; schema_ reference.4: Failed to read schema document ‘ http://code.alibabatech.com/schema/dubbo/dubbo.xsd ‘

(2) Reason: Generally speaking, the XSD file is backed up in the dependent jar package, so even if the link of the XSD file fails, it can still run. If the link fails and the XSD is not found, the jar package is not imported successfully.

(3) Solution:

<!--Use the maven-war-plugin plugin to specify the third-party jar package directory at compile time and introduce-->
			<plugin>
				<artifactId>maven-war-plugin</artifactId>
				<version>3.2.0</version>
				<configuration>
					<webResources>
						<resource>
							<directory>your_project_path/lib</directory>
							<targetPath>WEB-INF/lib</targetPath>
							<includes>
								<include>**/*.jar</include>
							</includes>
						</resource>
					</webResources>
				</configuration>
			</plugin>
