最佳答案
正如您可以在 this 等链接中关注的那样, this和 this .更有可能是 JDK 构建问题并恢复到较旧的 java.version
例如11.0.2 应该解决这个问题。
您可以同时订阅openjdk-build/issues/1214进一步更新。
When could this occur and what could cause this?
如果
jmod
为模块创建的文件在生成哈希时不一致。您可以引用JMOD tool详细说明对此负责的论点之一的文档--hash-modules regex-pattern
Determines the leaf modules and records the hashes of the dependencies directly and indirectly requiring them, based on the module graph of the modules matching the given regex-pattern. The hashes are recorded in the JMOD archive file being created, or a JMOD archive or modular JAR on the module path specified by the jmod hash command.
此外,在下沉部分中描述了
... This let’s you to allow a package to be exported to one or more specifically-named modules and to no others through qualified exports. The runtime verifies if the recorded hash of a module matches the one resolved at run time; if not, the runtime returns an error.
关于java - 错误 : Hash of java. xml (...) 与 java.base 中记录的预期哈希 (...) 不同,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/60904135/
