Answer 1

Edit: how about this?

  @Bean
  public EmbeddedServletContainerFactory embeddedServletContainerFactory() {
    return new TomcatEmbeddedServletContainerFactory() {
      @Override
      protected void postProcessContext(Context context) {
        ((StandardJarScanner) context.getJarScanner()).setScanManifest(false);
      }
    };
  }

Answer 2

Just trying to improve Oleg's excellent answer about Spring Boot 1.x..

Here's the corresponding code for Spring Boot 2.0 (Tomcat 8.5):

  @Bean
  public TomcatServletWebServerFactory tomcatFactory() {
    return new TomcatServletWebServerFactory() {
      @Override
      protected void postProcessContext(Context context) {
        ((StandardJarScanner) context.getJarScanner()).setScanManifest(false);
      }
    };
  }

Just add that to your application's configuration.

This is controllable via a property now:

# Comma-separated list of additional patterns that match jars to ignore for TLD scanning.    
server.tomcat.additional-tld-skip-patterns=*.jar

via AFTER upgrade from Spring boot 1.2 to 1.5.2, FileNotFoundException during Tomcat 8.5 Startup
