库源与类的字节码不匹配 [英] Library source does not match the bytecode for class

问题描述

不知道这里有什么问题..我从本地maven存储库中删除了所有文件，让它从头开始下载所有内容但是我无法摆脱这个错误：

No idea what's wrong here.. I removed all files I had from the local maven repository and let it download everything from scratch but I can't get rid of this error:

为什么我会看到这个以及如何摆脱它？

Why am I seeing this and how can I get rid of it?

推荐答案

IDEA没有任何问题，也没有依赖关系或本地maven缓存，它正确识别不匹配。

There's nothing wrong with IDEA, nor your dependencies or local maven caches, it's correctly identifying the mismatch.

以下是检查方法：

• 打开有问题的课程


• 点击显示差异


• 选择忽略空格和空行

你可以清楚地看到e（忽略JavaDoc和FQCN），类文件包含针对 @NonNull 注释参数的额外检查。导入说 lombok.NonNull ，以及文档表明这种转变将会发生。

You can clearly see (ignoring JavaDoc and FQCNs) that the class file has extra checks included for the @NonNull annotated arguments. The import says lombok.NonNull, and the documentation shows this transformation will happen.

我想最好的做法是要么忽略这个警告，要么让项目的维护人员从lombok构建sources.jar处理过的源代码，如果可能的话。我认为他们需要使用delomboking和这个Maven插件，但我自己从未构建过lombok代码。

I guess the best course of action is either to ignore this warning or ask the project's maintainers to build the sources.jar from the lombok-processed source code if that's possible. I think they'll need to employ delomboking and this Maven plugin, but never built lombok code myself.
