我如何知道Java程序需要运行哪些jar文件？

Question

Recently I was 最近我是 ~~trying to run 2048 bot 试图运行 2048机器人~~ ( upd : author deleted the project, but created the new one ). （ upd ：作者删除了该项目，但创建了新项目）。 But it just didn't work. 但这只是没有用。 And the developer said that it runs from Intelij IDEA just fine. 开发人员说，它可以从Intelij IDEA运行。 And yes, it appeared it does. 是的，看起来确实如此。 So what I did: 所以我做了什么：

>"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 runs it this way: Intelij IDEA通过以下方式运行它：

"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

Here are the jar files for convenience: 为方便起见，以下是jar文件：

So it starts with jdk 's jar files, then goes the project output directory, then some jar files, which are probably downloaded by Intelij IDEA on its own and it ends with the Intelij IDEA 's jar file, which is probably needed for debugging or something along those lines. 因此，它从jdk的jar文件开始，然后到项目输出目录，再到一些jar文件，这些文件可能由Intelij IDEA自行下载，并以Intelij IDEA的jar文件结束，这可能是调试所需的或类似的规定。

So, how do I know which jar files are needed and where do those ~/.m2 files come from? 那么，我如何知道需要哪些jar文件以及这些~/.m2文件从何而来？

UPD Here are probably the minimal jar files set to start this program: UPD以下可能是启动该程序所需的最少jar文件：

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

So it's not all the jar files even in m2 diretory. 因此，即使在m2目录中，也不是所有的jar文件。

UPD Selenium Client & WebDriver Language Bindings comes with additional jar files but not all of them are needed. UPD Selenium客户端和WebDriver语言绑定附带了其他jar文件，但并非全部都需要。 So one of the options was to specify all these jar files. 因此，选项之一是指定所有这些jar文件。 But I was able to make it work this way: 但是我能够使它以这种方式工作：

UPD Alternatively: UPD或者：

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

Answer 1

If you compile 如果编译

javac Program.java

then Program.class will be generated. 然后将生成Program.class 。 This must be in your classpath. 这必须在您的类路径中。

java -cp "Program.class;selenium-java-2.41.0.jar"

Answer 2

A Java program does not need any specific jar files to run, but it need the contained classes. Java程序不需要运行任何特定的jar文件，但是需要包含的类。 There are various tools and sites to help you find out: 有各种工具和站点可以帮助您了解：

How to find Jar to which an Java class belongs 如何找到Java类所属的Jar

There are also tools to help you manage those dependencies, like Maven (.m2 is related to it). 还有一些工具可以帮助您管理那些依赖项，例如Maven （与.m2相关）。 The author states that 作者指出

You will need to install the Selenium dependency somehow, such as by using Maven. 您将需要以某种方式安装Selenium依赖项，例如通过使用Maven。

IMHO the project should come with a pom.xml or the jars. 恕我直言，该项目应该带有pom.xml或jars。
