java Processbuilder-执行OS X上不在路径中的文件

Question

Okay i'm trying to make ChucK available in exported Processing sketches, ie if i export an app from Processing, the ChucK VM binary will be executed from inside the app. So as a user of said app you don't need to worry about ChucK being in your path at all.

Right now i'm generating and executing a bash script file, but this way i don't get any console output from ChucK back into Processing:

#!/bin/bash
cd "[to where the Chuck executable is located]"
./chuck --kill
killall chuck # just to make sure
./chuck chuckScript1.ck cuckScriptn.ck

then

Process p = Runtime.getRuntime().exec("chmod 777 "+scriptPath);
p = Runtime.getRuntime().exec(scriptPath);

This works but i want to run ChucK directly from Processing instead, but can't get it to execute:

String chuckPath = "[folder in which the chuck executable is located]"
ProcessBuilder builder = new ProcessBuilder
                              (chuckPath+"/chuck", "test.ck");

        final Process process = builder.start();
        InputStream is = process.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line;
        while((line = br.readLine()) != null) println(line);
        println("done chuckin'! exitValue: " + process.exitValue());

Sorry if this is newbie style :D

Answer 1

ProcessBuilder builder = new ProcessBuilder
                              (chuckPath+"/chuck", chuckPath+"/test.ck");

the args all need an absolute path.
