lombok 不起作用，即使它被添加为依赖项

Question

我用 Spring initializr 开始了我的项目，并添加了依赖项 lombok。 我的项目没有任何问题。 但是在我删除并重新安装 Intellij 之后，它开始不再识别注释@Builder或@Data 。 但正如我在重新安装 Intellij 之前所说的那样，一切正常。

我的错误信息：

Answer 1

您可能必须将 Lombok 插件安装到 Intellij 中，并在 Intellij 设置中设置“启用注释处理”选项。 此外，您的注释似乎很奇怪，您的意思是@Data 而不是@data？

Answer 2

go 到 maven 并点击清洁。 如果您已将项目导入 eclipse，请删除从 eclipse 添加的所有文件。 那必须是3个文件

Answer 3

您可能需要在 IntelliJ 中启用注释处理。 File->Settings->Compiler->Annotation Processors选中Enable annotation processing复选框，然后Apply和OK

Answer 4

确保在 IDE STS.ini 或 eclipse.ini 文件中添加了 -javaagent:lombok.jar
