Question

On a linux box I am making the following SVN import command:

svn import
           --non-interactive 
           --trust-server-cert 
           --username username 
           --password password 
           -m "a message" 
           /path/to/local.zip 
           https://sub.domain.net/path/to/export.zip

When calling it from the command line myself it works without a problem.

However, if I make this call using a a Java command prompt then I receieve an error message that there are too many arguments in the import command.

Does anyone know what could be causing this?

Additional notes

• If I copy and paste the Java generated svn import command from my log file to the console then the import works as expected.

• I am able to use SVN export command from within Java without any problems

• I have tried using single ' quotes

Edit

The code to make these calls are as follows:

private void exportToSvn()
    String command = String.format(
            "svn import --non-interactive --trust-server-cert " +
            "--username %s --password %s -m %s %s %s",
            username, password, "\"a message\"", "/path/to/local.zip",
            "https://sub.domain.net/path/to/export.zip"
    );
    command( command );
}

private void command( String... commands ) throws IOException, InterruptedException {
    Runtime rt = Runtime.getRuntime();
    for( String command : commands ){
        Process pr = rt.exec( command );
        BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
        logger.debug( command );
        String line;
        while ( (line = input.readLine()) != null)
            logger.debug("> " + line);
    }

After an anonymous tip (the commenter deleted their comment before I caught their name) – I found that the problem lay with the quotes as they cannot be escaped within Process (see this question).

String message = "\"Some message\"";    //quotes aren't escaped

I found a work around for this was to include the quotes in char format instead:

String message = String.format( "%sSome message%s", (char)34 );  //quotes as char
