JDK21与lombok插件的兼容性问题

最近在搭建一个demo项目。

基于老项目来配置，结果发生了一些错误。

java 复制代码

lombok 方法引用无效  找不到符号

解决办法:

使用最新的 lombok 版本.

例如:

xml 复制代码

    <dependencies>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.42</version>
            <optional>true</optional>
        </dependency>
    </dependencies>



    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <annotationProcessorPaths>
                        <path>
                            <groupId>org.projectlombok</groupId>
                            <artifactId>lombok</artifactId>
                            <version>1.18.42</version>
                        </path>
                    </annotationProcessorPaths>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <excludes>
                        <!--  在SpringBoot 的打包阶段不需要lombok-->
                        <exclude>
                            <groupId>org.projectlombok</groupId>
                            <artifactId>lombok</artifactId>
                        </exclude>
                    </excludes>
                </configuration>
            </plugin>
        </plugins>
    </build>

按照 stackoverflow 的说法:

The culprit is Lombok. The minimal Lombok version compatible with JDK 21 is 1.18.30.
