找不到Java 9自动模块

pin*_*kio 9 java intellij-idea maven java-9 module-path

我正在尝试定义Java 9模块.我已经定义了类似的东西:

module my.module.name {

}
Run Code Online (Sandbox Code Playgroud)

然后我的许多文件开始给我错误,他们找不到一些包.然后我使用了IntelliJ的自动帮助功能,它在我的module-info.java中添加了几个"require"语句.所以它变得像:

module my.module.name {
    requires spring.web;
    requires sshd.core;
    requires com.fasterxml.jackson.core;
    ....
}

现在IntelliJ显示我的所有代码没有错误.但是当我在"Maven Projects"窗口中单击"compile"时(我正在使用Maven 3.5.3和Oracle JDK 10进行编译),它告诉我以下内容:

src/main/java/module-info.java:[2,20] module not found: spring.web
src/main/java/module-info.java:[11,18] module not found: sshd.core
src/main/java/module-info.java:[13,35] module not found: com.fasterxml.jackson.core
...
same for the other modules I "require".

据我所知,未定义为模块的第三方库会生成"自动"模块.所以我发现了我需要的其中一个罐子:

C:\Users\<my username>\.m2\repository\org\springframework\spring-web\5.0.5.RELEASE\spring-web-5.0.5.RELEASE.jar
Run Code Online (Sandbox Code Playgroud)

并希望使用以下命令查看"自动"模块的名称:

jar.exe" --file=spring-web-5.0.5.RELEASE.jar --describe-module

No module descriptor found. Derived automatic module.

spring.web@5.0.5.RELEASE automatic
...

所以根据我的调查,我"需要"的模块的名称是正确的!我错过了什么?我为什么得到

module not found: spring.web

和其他模块一样吗?我错过了一些路径或什么?

编辑:根据要求,这是我的pom.xml:

然后尝试用"mvn compile -X"编译它以获得完整的调试日志,所以我得到了执行编译的命令行:

但又一次......我明白了

所有其他模块都一样......

EDIT3:

我创建了一个新项目,新项目编译得很好(但我仍然需要编译原始项目!).我做了同样的"mvn compile -X"命令​​,这是我得到的:

为什么我在新项目中获得"模块路径"以及Maven命令行中的许多其他选项而我在原始项目中没有得到它们?

好的,问题出在pom.xml中!我在编译期间收到“找不到模块”错误的原因隐藏在一个警告后面,我认为这并不重要,所以我没有在日志中粘贴这里。警告是“未找到 zip END 标头”。收到此警告的原因是我的依赖项中有一个“格式错误的 jar”,因此编译器在解析 module-info.java 文件时失败并产生上述错误。但哪个是“畸形”的罐子?结果出来了就是这个(我用的是一一排除的方法……):

我在搜索 apache sshd 时从https://mvnrepository.com获得了这种依赖,我不确定“type pom”是什么意思,但我猜是因为 Apache Mina 是一组几个项目,在这样你就包含了所有项目......无论如何,我只需要所有项目中的 apache-sshd-core,所以我将依赖项更改为以下(Apache Mina Dev 社区建议我这样做,所以非常感谢他们!!!):
