所以我试图导入Unirest for java来发出简单的 http 请求。现在我遇到了关于 Apache 依赖项的重复依赖项的警告。我首先想到通过将其添加到 build.grandle 来解决这个问题：
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
这确实让它运行了，但是一旦我使用了 Unirest 的任何功能，它仍然会崩溃。于是回到google来到了这个帖子。唯一的答案指向我决定遵循的本教程。所以我下载了mvn。首先在 JAVA_HOME 上遇到了一些问题，但设置正确。然后我像他一样做了：mvn clean assembly:assembly编辑 pom.xml 后在 github 目录的主文件夹中执行
但是，对我来说，它并没有像他那样生成 .jar 文件。
我究竟做错了什么？有人可以为我创建它吗:)？
我确实得到了一个target应有的文件夹，cmd它正在下载一堆文件，但没有 .jar 文件。
在 Target 文件夹中，我有 4 个子文件夹：classes、maven-status、surefire-reports、test-classes。
一些堆栈跟踪：在 cmd
