[英]Java - Build and run eclipse project from command line
I have a java project written using eclipse ide and I want to run it through ssh on a different machine, but I have to do this using the command line and I don't know exactly how. 我有一个使用eclipse ide编写的java项目,我想在不同的机器上通过ssh运行它,但是我必须使用命令行来完成这个,我不知道具体如何。
I am a beginner at both shell commands and java. 我是shell命令和java的初学者。
Could you please give me a useful link with answers regarding this question, or perhaps a set instructions of how to do this? 你能否给我一个有用的链接,提供有关这个问题的答案,或者可能是如何做到这一点的一套说明?
Maven or Ant are the best option but for an Eclipse-only solution Maven或Ant是最佳选择,但仅限于Eclipse解决方案
you can choose File -> Export and select Java -> Runnable JAR File 您可以选择File - > Export并选择Java - > Runnable JAR File
then transfer the JAR file to your other machine and run this from the command line: 然后将JAR文件传输到另一台机器并从命令行运行:
java -jar YOUR.JAR
You can run Java applications from the command line. 您可以从命令行运行Java应用程序。 The simplified syntax looks like this:
简化的语法如下所示:
java -cp <classpath> <main class> <args>
where: 哪里:
<classpath>
- list of directories and/or JAR-files where needed classes reside separated by ";" <classpath>
- 所需类通过“;”分隔的目录和/或JAR文件列表 for Windows or ":" for linux (default classpath is "." - the current directory); 对于Windows或“:”对于linux(默认类路径为“。” - 当前目录);
<main class>
- fully qualified name of the class containig main() method (for example, org.myself.HelloWorld) <main class>
- 类containsig main()方法的完全限定名称(例如,org.myself.HelloWorld)
<args>
- various arguments for application if any. <args>
- 应用程序的各种参数(如果有)。
So, if you find the directory where Eclipse stored compiled classes (usually it's bin) you may use the command, like 因此,如果您找到Eclipse存储编译类的目录(通常是bin),您可以使用命令,例如
java -cp . my.package.MyClass
Or, if you use some libraries and classes in other directories, it could be: 或者,如果您在其他目录中使用某些库和类,则可能是:
java -cp some-cool-lib.jar:another-lib.jar:/some/directory/with/classes my.package.MyClass
