如何知道java程序需要运行哪些jar文件？

2 周，1 日 Questions & Answers 4786

最近我是~~trying to run 2048 bot~~（upd：作者删除了该项目，但创建了the new one）。但它就是不起作用。开发人员说它从Intelij IDEA运行很好。是的，看起来确实如此。所以我所做的是：

>"c:\Program Files\Java\jdk1.7.0_51\bin\javac.exe" Program.java -cp selenium-java-2.41.0.jar
Note: Program.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

>java Program -cp selenium-java-2.41.0.jar
Error: Could not find or load main class Program

Intelij IDEA按以下方式运行：

"C:\Program Files\Java\jdk1.7.0_51\bin\java" -Didea.launcher.port=7532 "-Didea.launcher.bin.path=C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 13.1.1\bin" -Dfile.encoding=UTF-8 -classpath "C:\Program Files\Java\jdk1.7.0_51\jre\lib\charsets.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\deploy.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\javaws.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\jce.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\jfr.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\jfxrt.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\jsse.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\management-agent.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\plugin.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\resources.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\rt.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\access-bridge-64.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\dnsns.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\jaccess.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\localedata.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\sunec.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\sunjce_provider.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\sunmscapi.jar;C:\Program Files\Java\jdk1.7.0_51\jre\lib\ext\zipfs.jar;C:\Users\Yuri\Desktop\2048_bot\2048_Bot_2.0-master\target\classes;C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-firefox-driver\2.39.0\selenium-firefox-driver-2.39.0.jar;C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-remote-driver\2.39.0\selenium-remote-driver-2.39.0.jar;C:\Users\Yuri\.m2\repository\cglib\cglib-nodep\2.1_3\cglib-nodep-2.1_3.jar;C:\Users\Yuri\.m2\repository\org\json\json\20080701\json-20080701.jar;C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-api\2.39.0\selenium-api-2.39.0.jar;C:\Users\Yuri\.m2\repository\com\google\guava\guava\15.0\guava-15.0.jar;C:\Users\Yuri\.m2\repository\org\apache\httpcomponents\httpclient\4.3.1\httpclient-4.3.1.jar;C:\Users\Yuri\.m2\repository\org\apache\httpcomponents\httpcore\4.3\httpcore-4.3.jar;C:\Users\Yuri\.m2\repository\commons-logging\commons-logging\1.1.3\commons-logging-1.1.3.jar;C:\Users\Yuri\.m2\repository\commons-codec\commons-codec\1.6\commons-codec-1.6.jar;C:\Users\Yuri\.m2\repository\org\apache\commons\commons-exec\1.1\commons-exec-1.1.jar;C:\Users\Yuri\.m2\repository\net\java\dev\jna\jna\3.4.0\jna-3.4.0.jar;C:\Users\Yuri\.m2\repository\net\java\dev\jna\platform\3.4.0\platform-3.4.0.jar;C:\Users\Yuri\.m2\repository\commons-io\commons-io\2.2\commons-io-2.2.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 13.1.1\lib\idea_rt.jar" com.intellij.rt.execution.application.AppMain Program

C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 13.1.1\lib\idea_rt.jar" com.intellij.rt.execution.application.AppMain Program

因此，它从jdk的jar文件开始，然后进入项目输出目录，然后是一些jar文件，这些文件可能是由Intelij IDEA自己下载的，最后是Intelij IDEA的jar文件，这可能是调试或类似工作所需要的

那么，我如何知道需要哪些jar文件以及这些~/.m2文件来自哪里

UPD以下可能是启动此程序所需的最小jar文件集：

C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-firefox-driver\2.39.0\selenium-firefox-driver-2.39.0.jar
C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-remote-driver\2.39.0\selenium-remote-driver-2.39.0.jar
C:\Users\Yuri\.m2\repository\org\json\json\20080701\json-20080701.jar
C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-api\2.39.0\selenium-api-2.39.0.jar
C:\Users\Yuri\.m2\repository\com\google\guava\guava\15.0\guava-15.0.jar
C:\Users\Yuri\.m2\repository\org\apache\httpcomponents\httpclient\4.3.1\httpclient-4.3.1.jar
C:\Users\Yuri\.m2\repository\org\apache\httpcomponents\httpcore\4.3\httpcore-4.3.jar
C:\Users\Yuri\.m2\repository\commons-logging\commons-logging\1.1.3\commons-logging-1.1.3.jar
C:\Users\Yuri\.m2\repository\org\apache\commons\commons-exec\1.1\commons-exec-1.1.jar

因此，即使在m2目录中，也不是所有的jar文件

UPDSelenium Client & WebDriver Language Bindings附带了额外的jar文件，但并非所有文件都是必需的。因此，其中一个选项是指定所有这些jar文件。但我能做到这一点：

UPD或者：

find -name '*.jar' -execdir cp -t ~/path/to/prj {} +

如果你编译
```
javac Program.java
```
然后将生成Program.class。这一定在你的类路径中
```
java -cp "Program.class;selenium-java-2.41.0.jar"
```
# 2 楼答案
Java程序不需要运行任何特定的jar文件，但需要包含的类。有各种工具和网站可以帮助您找到：
- How to find Jar to which an Java class belongs
还有一些工具可以帮助您管理这些依赖关系，比如Maven（.m2与之相关）。提交人说

You will need to install the Selenium dependency somehow, such as by using Maven.

我想这个项目应该有一个pom。xml或罐子
