我一直在尝试设置不可变库，但是尽管遵循了指南，eclipse似乎没有在target/generated sources/annotations文件夹中生成任何类
下面是java编译器->注解处理设置的屏幕截图
在工厂路径中，显示不可变值-2.8.2.jar是根据不可变指南选择的--https://immutables.github.io/immutable.html.
我运行了project->clean，然后是project->buildall
我在错误日志中得到一个错误：exception抛出java注解处理器org.immutables.processor。proxyprocessor@63924c86
以及相应的堆栈跟踪

您的不可变jar太新或太旧（或者您用来运行eclipse的java版本太新或太旧）。
您可以在eclipse中检查java版本：找到“about eclipse”选项（在macs上的eclipse菜单下，在其他操作系统上我认为它在“help”下），然后选择configuration选项卡。检查是否有故障
java.home=....其中的条目将指向用于启动eclipse本身的jvm。也就是抛出那些错误，或者，不可变系统附带了一个内部编译器（ecj通常是项目使用的java解析器，因为它是快速的、开源的），在这种情况下，就是抛出错误的那个。从堆栈轨迹很难判断是谁的错。所以，我会检查您的不可变dep的版本，如果它非常旧，请更新它。然后我会检查运行eclipse的vm，如果它非常旧，请更新它。
实际上，我会抛弃不可变的，只使用lombok，但是，我会：p
