[jbang] [2025-05-26 18:35:28] Runtime.exit() called with status: 1

Expected behavior
This is a known issue in the world of Windows. IntelliJ has a workaround that can be enabled which saves all the command arguments and long classpath to a text file which is than passed to a program as "program.exe @arguments.txt"

JBang version
0.126.1

Additional context
I don't think this is Kotlin specific and the same error can potentially occurr with Java, or Groovy scripts.
java.exe and javac.exe support the shortened comand-line @arguments.txt convention. kotlinc.bat supports it as well.

java:

• @argument files - One or more argument files containing options

javac:

• @<filename> - Read options and filenames from file
  kotlinc:

• @<argfile> - Read compiler arguments and file paths from the given file.

Intellij shortened command-line

• https://www.baeldung.com/intellij-idea-command-line-is-too-long

Proposed Solution

Modify JBang to always use an @arguments file when starting Windows processes.

For example , invoke the Kotlin compiler as:

....\kotlincs\2.0.21\kotlinc\bin\kotlinc.bat @arguments.txt

[wfouche]

CommandBuffer.java contains code that shows that JBang already supports the @argument file workaround.

	public CommandBuffer usingArgsFile() throws IOException {
		// @-files avoid problems on Windows with very long command lines
		final Path argsFile = Files.createTempFile("jbang", ".args");
		try (PrintWriter pw = new PrintWriter(argsFile.toFile())) {
			// write all arguments except the first to the file
			for (int i = 1; i < arguments.size(); ++i) {
				pw.println(escapeArgsFileArgument(arguments.get(i)));
			}
		}
		return CommandBuffer.of(arguments.get(0), "@" + argsFile);
	}

	public CommandBuffer applyWindowsMaxLengthLimit(int maxLength, Util.Shell shell) throws IOException {
		String args = asCommandLine(shell);
		// Check if we can and need to use @-files on Windows
		if (args.length() > maxLength && Util.getShell() != Util.Shell.bash) {
			return usingArgsFile();
		} else {
			return this;
		}
	}

I'll dig deeper.

@quintesse , how is the temp argsFile removed? Should there not be a line like

argsFile.toFile().deleteOnExit();

just after the call to Files.createTempFile?

@quintesse , I don't think this line of code will work for Bash on Windows.

if (args.length() > maxLength && Util.getShell() != Util.Shell.bash) {

how is the temp argsFile removed? Should there not be a line like

It's not, Java exits before the code is being run (in case of the compiler perhaps not, but in case of running the code it is, we don't distinguish between the two cases) deleting it would make the next step fail. It's a case of "well, too bad".

I don't think this line of code will work for Bash on Windows.

Why not? AFAIK the bash on Windows handles long command lines just fine?

[quintesse]

The fact that Kotlin and Groovy don't work doesn't surprise me, I don't think that has ever been tested. We'd have to see how they implement the handling of long lines on Windows.

according to https://kotlinlang.org/docs/compiler-reference.html#argfile and https://groovy-lang.org/groovyc.html they both support @argfile style arguments thus should be doable to apply same as done for javac.

anyone up for doing a PR ?

anyone up for doing a PR ?

I've started running JBang in the IntelliJ debugger to see what is going wrong. Will have more time next month to look at this, and create a fix.
