org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans-3.0.xsd' - spring

Question

I am getting Exception and I am not able to figure out the reason why I am getting this error. Actually I’ve to produce an executable jar. When I run my class in eclipse it works fine. But, when I export this as executable jar using Maven plug-in it gives following error. Following are the files for your reference.

Answer 1

I was having the same issue. I think you are trying to assemble all classes and dependencies into one executable jar file.
Based on the exception you are seeing, the Spring failed to validate the xsd.
If you open the META-INF/spring.schemas, you can see all the xsd configurations there.
You can try to use this plugin configuration file in your pom file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>at.seresunit.lecturemanager_connector.App</mainClass>
</transformer>
<transformer
implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.handlers</resource>
</transformer>
<transformer
implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.schemas</resource>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
