从终端或命令提示符（如 git 或 maven 或 java 或 javac）运行（不是在开发期间而是在生产中）java 应用程序

Question

I have created my Java CLI application (maven, executable jar). Everytime I want to run it I have to put java -jar myapp.jar. How can I make it run without putting "java -jar"? The same way git runs eg git add . or like maven eg mvn package . I want it to run like myapp create 'file-name' where myapp is the name of my application? I want to open terminal and just type the name of my application and put arguments.

Are we talking windows or linux? What you typically do is create a batch or bash script to will run the java executable with the correct parameters. For example, on linux you can add a script in /usr/local/bin/myprogram with something like this in the contents:

!/bin/bash
/usr/bin/java [options] -jar /usr/local/libs/myprogram.jar $*

On windows you can create a batch file. What you typically do is in the installation directory of your jar file, add a myprogram.bat with something like this in the contents:

@ECHO OFF
%JAVA_HOME%\bin\java [options] -jar myprogram.jar %*

Then put your jar in the right place and you can execute it anywhere with myprogram . Now if you add your directory to the PATH environment variable, you can execute this program anywhere from the command line.

For example, see https://www.java.com/nl/download/help/path.xml for adding things to you path.
