Split command line to arguments

Question

I need to launch an external Java process. Arguments are formed elsewhere and are passed to me as a single string. I need to find a certain "-D" key and update its value before actually running a process.

Example:

java -Dosgi.framework.extensions="foo bar" "fdf -Dosgi.framework.extensions=bim bom" 

Should become:

java -Dosgi.framework.extensions="bar" "fdf -Dosgi.framework.extensions=bim bom" 

How do I properly tokenize arguments? Obviously splitting by space is not an option. I'd like to use a plugin from Eclipse infrastructure, if possible.

Answer 1

看看这个 ， 这是一个有助于命令行选项的API。

Answer 2

I ended up using org.eclipse.debug.core.DebugPlugin.parseArguments . Unfortunately is escapes the result and I'm not sure why and how does that affects the final result. Nevertheless it is passing my tests.
