当尝试运行 Maven Enforcer 时,由于某些类符合 1.9,而整个项目仅限于 1.8,因此失败。以下是日志的堆栈跟踪。该特定依赖项是由不同的 jar 拉取的,由于它具有编译时依赖项,因此无法排除该依赖项。

看来您误解了enforceBytecodeversion的意图...它将检查所有依赖项,如果它们使用字节码作为更新版本,这意味着高于JDK 8,只是提升 maxJdkVersion 并不能解决问题。该问题与您正在使用的依赖项有关......
The dependency: javax.json.bin:javax.json.bind-api
contains a `module-info.class` file which is related to JDK 9 ...

如果您确定该依赖项中的所有代码都不使用 JDK 9 特定的内容,则您必须module-info.class从检查执行器规则中排除...
