Revisiting the conflict of lombok with java runtime compilation

阅读更多关于 Revisiting the conflict of lombok with java runtime compilation

问题 I am working in IntelliJ Idea, with JDK and JRE 8. The project makes use of lombok, and I would like to have code generation and runtime compiling. My aim is to produce a code that does the same task as some complicated runtime generated lambda function, to speed up the evaluation. The project makes heavy use of lombok. And I have the same issue as the one discussed here, so I know that one way around this problem is to add particular dependencies. My question is: did there appear any other,

问题 so I'am writing simple Spring Boot(version 1.56) Application. And started using Project lombok, specifically@Slf4j feature for logging. Logging works fine, but how can I configure this logger? To be precise I want to be able to change logging level using external file. 回答1: It has nothing to do with lombok , it is about slf4j configuration. It should be done by updating your application.properties file. You can check here and here 来源： https://stackoverflow.com/questions/46222068/project

Lombok generated code can not be ignored on coverage

阅读更多关于 Lombok generated code can not be ignored on coverage

问题 Here I asked the question: Lombok, use only getter setter not equals or tostring I did not want to comment there, because it was very old. What I want is, I want the code which is generated by lombok to be ignored during coverage of inteljidea and also sonar. As suggestion in my previous question that I linked , I added this config.stopBubbling = true lombok.addLombokGeneratedAnnotation = true I added this to root ,then rebuilded recoveraged. But for that class @Data @EqualsAndHashCode

IntelliJ IDEA 的 main方法，for循环，syso的快捷键

阅读更多关于 IntelliJ IDEA 的 main方法，for循环，syso的快捷键

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 今天偶然发现了IntelliJ中创建main函数的快捷键，依次还有for循环，System.out.println(); 在编写代码的时候直接输入psv就会看到一个psvm的提示，此时点击tab键一个main方法就写好了。 main方法： psvm 也就是public static void main的首字母。 for循环依次还有在方法体内键入for会有一个fori的提示，选中然后tab键，就会自动创建一个for循环。 System.out.println() 如何像写一个System.out.println();就是sout 知道了这个规律，应该还有很多类似的用法。更多的提示可以CTRL + j 可以查看，mac系统下是command＋j 。推荐插件：（1）HighlightBracketPair：自动化高亮显示光标所在代码块对应的括号，可以定制颜色和形状（2）Rainbow Brackets：彩色显示所有括号，对单行嵌套括号有用（3）.ignore：生成各种ignore文件，一键创建git ignore文件的模板，免得自己去写（4）Key promoter X ：快捷键提示插件，每进行一个鼠标操作，会提示你对应的快捷键是啥（5）lombok：支持lombok的各种注解

问题 Builds with Gradle 5.2.1 and Lombok 1.18.6 dependency are failing with JDK 10. It seems Lombok annotation are not being processed appropriately. I keep getting "cannot find symbol" error across various Java files in my source. Any thoughts on why this might be happening?
