Gradle，Lombok和JPAMetalModel处理器：项目不存在't compile (package lombok doesn't）

我在我的gradle项目中使用lombok并且想要创建一个jar文件，但每次我执行jar任务（无论是否在我的控制台或eclipse ide中触发）我得到的错误是我的lombok导入无法在我使用的那些类中找到lombok注释 . 示例输出：

经过一段时间的搜索，我发现有一个gradle和lombok的插件，但是对于使用较新的gradle版本进行编译并不是真的需要 . 我的gradle版本是3.4.1和lombok 1.6.18 .

在another thread我发现可能有一个类似的错误，但与maven . 我想在我的build.gradle中尝试这个，但我不知道如何编写/定义这个...

使用我的Eclipse ide启动和运行我的Spring启动应用程序工作正常;只有gradle compileJava任务在编译时似乎与lombok有问题 .

这是我的build.gradle：

        mavenCentral()
        jcenter()
    }
    dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:+") }
