How to invoke one more java process from java program

I want to execute mvn exec:java开发者_JS百科 command from a java program.

Please help me in this problem.

Most probably java can not find "mvn" executable. Maintaing PATH variable and finding executables is a function of a command line shell (cmd, bash, etc..). Runtime.exec() does not use your shell.

You need to supply full path to executable for Runtime.exec() to find it.
