Reproduce the report by creating a Web project with Spring Initializer in IntelliJ IDEA 2019.2.4 on macOS, then inspect the AlibabaClassMustHaveAuthor inspection and the com.alibaba.p3c.smartfox plugin exception. Done means the generated DemoServlet no longer causes this reported PluginException during inspection.
