龙目岛与Gradle构建

Question

I am trying to develop a web application with SpringBoot and Lombok to reduce boilerplate code.

While the annotated class works fine, I am getting compilation errors in target classes.

I am not trying to compile via IDE but directly via commandline using gradlew build.

Any suggestion on how to integrate Lombok with gradle to build and generate jars will be really helpful.

Git repository: https://github.com/ashubisht/sample-sbs.git

The error I am getting is:

\sample-sbs\src\main\java\com\sample\springboot\Controllers\RestControllerClass.java:28:
 error: constructor Customer in class Customer cannot be applied to given types;

 customerDAO.insert(new Customer(1, "Utkarsh", 25));
                               ^

 reason: actual and formal argument lists differ in length

Customer class is annotated with @Data annotation.

Answer 1

In the current lombok release 1.18.0 there is an issue with Gradle 4.9 , which will be fixed in the upcoming lombok release 1.18.2.

If you are using Gradle 4.9, either downgrade Gradle, wait for lombok 1.18.2, or use the current lombok edge release .

Answer 2

In your Customer class, all the fields that you're trying to initialize in the constructor are non-final.

Since @Data annotation adds only @RequiredArgsConstructor , you cannot initialize non-final fields in the constructor without explicitly annotating this class with @AllArgsConstructor .

So you either need to annotate the class with @AllArgsConstructor , or use setters to initialize the object.
