如何定位出错误信息？
写一个配置类（或用现有配置类），发布一个bean。

@Configuration
public class XxxConfig {
    @Bean
    public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory factory =
                new TomcatEmbeddedServletContainerFactory();
        return factory;
    }
}

再次运行，会将错误信息打印出来。如本次调试出的错误：

[INFO] --- maven-compiler-plugin:3.1:testCompile (default-testCompile) @ demo ---
[INFO] Changes detected - recompiling the module!

将本地仓库对应包文件夹删除，等待mvn重新下载完即可。
