我在gradle项目中使用com.fasterxml.jackson.core:jackson-annotations:2.6.0。自从将com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.6.0添加到我的项目构建文件中以来，我在运行gradle项目时一直遇到这个异常。这是我的错误的堆栈跟踪。

我在课堂上使用了未使用的@JsonFormat。但我确实有JsonSerializer和JsonDeserializer注释，它们使用两个类在UTC中将我的ZonedDateTime序列化到Json和从Json反序列化。我是第一次进行序列化和反序列化，所以请给出任何建议。

检查您的项目依赖关系。您可能正在使用不兼容的库版本。2.7版本有empty()方法，而2.6版本没有。
http://fasterxml.github.io/jackson-annotations/javadoc/2.6/com/fasterxml/jackson/annotation/JsonFormat.Value.html
http://fasterxml.github.io/jackson-annotations/javadoc/2.7.0-rc1/com/fasterxml/jackson/annotation/JsonFormat.Value.html
尝试升级到2.7版本。
我在尝试运行task-gradle-clean时解决了问题。我认为一些旧的项目依赖关系一直存在到现在。这只是一个清理项目的问题。该项目现在运行良好。：)
这是@BeñatBermejo和@AkashRaveendran已经给出的解决方案的替代方案。我很高兴阿卡什仅仅通过清理环境就能让他的系统正常工作，但我发现这对我来说还不够。
这个错误来自jackson数据绑定，我在我的pom 2.8.1版本中有这个数据绑定。然而，由于我也涉及Spring，所以jackson数据绑定依赖项，即jackson核心，仍然是2.6.6版本。
我所要做的就是删除jackson数据绑定依赖项中的版本说明符。当我这样做的时候，Maven使用了Spring命名的版本2.6.6，它不包括对JsonFormat$Value.empty().的调用
如果您需要一些jackson 2.7+功能，您可以尝试指定更高版本的jackson核心以及您尝试使用的jacksonartifact的任何其他依赖项。
然而，在涉及Spring的情况下，我想看看您是否可以使用它所命名的较低的jackson版本，或者看看Spring是否已经发布了一个包含较新jackson库的新版本。重写Spring的依赖关系结构首先破坏了使用Spring的最大原因之一：您可以立即获得一组经过充分测试的相互关联的依赖关系。
从.m2目录中删除所有jackson文件，确保您的所有jackson-pom，即数据绑定、注释等具有相同的版本。如果需要，请降级您的版本，即jackson 2.7.3运行良好，而不是2.10.3
