Java 无法从 Artifactory 下载文件的代码

Java code to download files from Artifactory not working

我的项目结构如下。

$tree
.
├── [4.0K]  src/
│   └── [4.0K]  main/
│       └── [4.0K]  java/
│           └── [4.0K]  org/
│               └── [4.0K]  jfrog/
│                   └── [4.0K]  example/
│                       └── [6.2K]  ClientExample.java
├── [1.3K]  pom.xml
└── [ 781]  README.md

这是来自

的示例程序

JFrog artifactory java client maven example

如果我这样做 mvn compile 我会得到以下输出。

如果我尝试运行生成jar文件。

java -jar target/maven-example-1.0-SNAPSHOT.jar

我收到以下错误。

no main manifest attribute, in target/maven-example-1.0-SNAPSHOT.jar

因为这是来自 JFrog github repository 我希望它能工作。我做错了什么?

将项目导入 IntelliJ IDE 构建并尝试 运行 给出以下结果。构建看起来成功 (jar file gets generated inside target folder)

然而,当我按 运行 时,我被定向到以下页面。

pom.xml 不包含构建 运行nable jar 文件的说明。 (而且 README 没有提到你可以 运行 那样做)

运行最简单的方法是将项目导入到支持maven项目的IDE(Eclipse、IntelliJ等)中,运行主要class 从那里。
