java - 如何在intellij上正确编译jnativehook？

Question

我很确定我一切都正确，但它只是无法编译 website 上发布的示例

这是我的 POM.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>

<groupId>com.1stleg</groupId>
<artifactId>jnativehook</artifactId>
<version>2.1.0</version>
<name>JNativeHook</name>

这是 cmd 的错误输出:

PS C:\Users\XXX\IdeaProjects\Defa_Kalenteri\src\main\java> javac -classpath ./JNativeHook.jar 
GlobalKeyListenerExample.java
GlobalKeyListenerExample.java:2: error: package org.jnativehook does not exist
import org.jnativehook.GlobalScreen;
                  ^
GlobalKeyListenerExample.java:3: error: package org.jnativehook does not exist
import org.jnativehook.NativeHookException;
                  ^
GlobalKeyListenerExample.java:4: error: package org.jnativehook.keyboard does not exist
import org.jnativehook.keyboard.NativeKeyEvent;
                           ^
GlobalKeyListenerExample.java:5: error: package org.jnativehook.keyboard does not exist
import org.jnativehook.keyboard.NativeKeyListener

这是我的 github如果你想尝试一下。找到文件 GlobalKeyListenerExample.java 并尝试编译它。

您没有将 jnativehook 列为依赖项。您列出的 pom 不是您应该在项目中使用的 pom，而是定义您尝试使用的工件的 pom。你的 pom 应该看起来更像这样:
