版本组合（Java9 Jigsaw项目中的Maven/Log4J）

Question

我正在尝试使用 Maven 和 IntelliJ 中的 Java 10 将一个非常简单的 JavaFX 应用程序运行。

项目： https://github.com/ClanWolf/C3-Client_Phoenix

结构：

模块-info.java:

module net.clanwolf.c3.client {
    requires javafx.graphics;
    requires javafx.fxml;
    requires javafx.controls;
    requires javafx.base;
    requires org.apache.logging.log4j;
    exports net.clanwolf.c3.client;
}

pom.xml:

这不是运行。 Maven 构建完成没有问题，但如果我在 IntelliJ 中启动它，它会给我这个：

引导层初始化出错 java.lang.module.ResolutionException：模块 maven.core 和 maven.artifact 将包 org.apache.maven.artifact.resolver.filter 导出到模块 aether.impl

如果我确实删除了对 log4j-core 的依赖，它会运行，但它会在运行时抱怨没有 log4j 的实现，我应该添加 log4j-核。如果我这样做，则再次显示 Resolution Bullshit。如果可能的话，如何解决这个问题？

Answer 1

Java 9 模块化带来了一些新规则，例如：Split packages，即类具有相同的包但在不同的罐子中，是不允许的。这只是在处理模块路径时的问题，而不是传统的类路径。似乎 intellij 出于错误的原因决定切换到模块路径，可能是因为 log4j 有一个模块描述符。

Answer 2

毕竟问题在于 maven-compiler-plugin 作为依赖项在 pom.xml 中。这不是必需的，因为它仅在打包期间使用。在我删除它之后，错误消失了。
