我在个人nexus maven存储库中有一些工件，它们在Java 8项目中都很有用。与Java 9 maven项目一起使用时，这些工件都无法工作：
Library Maven: io.adenix.spring.util:response-util:2.0.0.M1-SNAPSHOT has broken classes path:
/Users/adenix/.m2/repository/io/adenix/spring/util/response-util/2.0.0.M1-SNAPSHOT/response-util-2.0.0.M1-SNAPSHOT.jar
我已经烧掉了一天中最好的部分，试图在线查找资源，解释如何迁移我的工件以使用Java 9但没有成功。
我正在寻找：

删除module-info.java允许它在模块名称response.util下工作。这让我相信module-info.java中缺少某些内容。
我暂时解决了删除module-info.java的问题，但我希望能够像春天一样选择名称。我将看看他们的v5预发布是否公开，如果在任何地方公开，看看他们是如何做到的。任何帮助表示赞赏。
答案 0 :(得分：1)
您的模块在module-info.java中被称为 adenix.response ，因此依赖性使用方的需要语法变为
requires adenix.response
以下是module-info.java的组件
module module.name // *module name* not package name of current module. This is the name other modules will add under requires
{
requires other.module.name; // *module name* of another module current module is dependent on
exports some.package; // *package* which current module is going to export
}
以下案例可能有助于解释module-info.java中的组件
制片人 module-info.java
module adenix.response { // Module name
requires spring.web; // Dependency module name
exports io.adenix.spring.util; // Package name which is exported
}
消费者 module-info.java
module some.module {
requires adenix.response; // Module name of Producer
}
如何更改名称：
制片人 module-info.java
module my.awesome.module { // Module name
requires spring.web; // Dependency
exports io.adenix.spring.util; // Package name which is exported
}
消费者 module-info.java
module some.module {
requires my.awesome.module; // Module name of Producer
}
