Question

注意：由于我在my original question中给出了错误的答案，因此我不再受到任何关注。我知道程序员的想法：他们会在我的问题中看到“ 1个答案”，甚至不会公开。不要怪我，我该怎么办？我仍然没有找到解决这个问题的方法：（

当我尝试使用maven，java模块和junit 5运行一个简单项目时，出现以下错误消息：

 Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project echo: Compilation failure: Compilation failure:

这是我的目录结构：

echo
----src/main/java
--------com.udp.echo
------------App.java
------------EchoClient.java
------------EchoServer.java
--------module-info.java
----src/test/java/com.udp.echo
--------EchoTest.java
----pom.xml

这是我的module-info.java文件：

open module echo {
    requires junit;
}

我实际上试图做require org.junit.jupiter.api和require org.junit.jupiter.engine，但这不会改变结果。

这是我的pom.xml

这是运行mvn -v的结果：

$ mvn -v

Maven是否不应该从Maven存储库下载其依赖项？如果是这样，为什么它抱怨找不到模块？这对我来说毫无意义。

我想念什么？

Maven编译错误：找不到模块：junit（重新发布）
