Eclipse plugin that helps with the development of Spring Boot. Some capabilities are:

• Warns about @Configuration classes that use field injection
• Warns about unnecessary use of @Autowired on classes with a single constructor
• Quick fix for converting a configuration class from constructor injection to field injection
• Reports an error if a FailureAnalyzer is not listed in META-INF/spring.factories
• Warns about the use of @Component in main code
• Warns about public or protected functional interfaces in main code that are not annotated with @FunctionalInterface
• Warns about single parameter lambda expressions that do not enclose the parameter in parentheses
• Quick fix for enclosing a lambda expression's single parameter in parentheses
• Warns about lambda expressions with a block body containing a single statement
• Warns about unused method parameters in main code
• Reports an error if a usage of AssertJ's assertThat(…) is incomplete
• Warns about packages in main code that contain public or protected classes but no package-info.java file
• Warns if a javadoc @link to an annotation does not use @AnnotationName as the link's text
• Warns if fail() is used in a try-block or assertThat() is used in a catch block, recommending the use of AssertJ's exception assertion support instead
• Reports an error if an unproxied @Bean method is called directly
• Warns when a @Bean method is declared on a non-@Configuration class
• Warns when a non-@Configuration class extends a class with @Bean methods
• Reports an error when a @Configuration class that disables bean method proxying extends a @Configuration class that uses bean method proxying
• Warns when String.indexOf(String) and String.lastIndexOf(String) are called with a single-character string literal and recommends the use of their char variants instead
