将进度条链接到 Install4j 中的批处理文件执行

Question

Can I link a progess bar to install4j's execution of a batch file?

I can execute my batch file or shell file via ProcessBuilder but I'm not sure how to signal progress bar in install4j

Run Script Step

File installationDir = new File((String)context.getVariable("sys.installationDir"));
File executable = new File(installationDir, "bin/start.sh");
File logFile = new File(installationDir, "autorun.out.log");

ProcessBuilder pb = new ProcessBuilder(executable.getAbsolutePath(), 
"-p", (String)context.getVariable("projectsdir"),
"-n", (String)context.getVariable("projectname"));

 pb.redirectErrorStream(true);
 pb.redirectOutput(logFile);
 pb.directory(installationDir);
 Process p = pb.start();
 p.waitFor();
return (p.exitValue() == 0);

If a progress bar is visible on a screen you can set the progress by calling

context.getProgressInterface().setPercentCompleted(...);

You need a percent value for that purpose. If you don't have such a value, you can set the progress bar to indeterminate by calling

context.getProgressInterface().setIndeterminateProgress(true);

Setting the progress is also possible with the "Set the progress bar" action.
