Compile Multiple Classes and pass command line arguments
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
How would I compile two classes using command line(without the use of additional software) and pass arguments to it?
I've created myself a sources.txt file which contains definitions where each class is. I did this by using the following command
dir /s /B *.java > sources.txt
Then I try to do javac @sources.txt although that does not help as I'm getting the following error:
error: invalid flag: C:UsersAdrian
Usage: javac <options> <source files>
use --help for a list of possible options
Additionally, my path does contain one space, after my username. Adrian $. So in sources.txt it looks like this: C:UsersAdrian $
I did try putting quotes around them or percentage sign but then I get error which specifies that the file was not found.
Full Main code:
package me.adrian;
import java.io.FileNotFoundException;
public class Main {
public static void main(String args) {
CSVoperator CSVfile = new CSVoperator();
try {
CSVfile.readCSV(args); //get args into there.
}
catch (FileNotFoundException e){
e.printStackTrace();
}
}
}

You can compile directly by specifying multiple names in on command
javac file1.java file2.java
or by using *, all .java files that are in current directory will be compiled
javac *.java

Since your paths contain space they has to be quoted. You can do it by iterating over sources.txt in a loop and quoting the entire line:
FOR /F %%i IN (sources.txt) DO "javac %%i"
or you can try dir /x to generate sources.txt with a short path as per dir docs
/x
Displays the short names generated for non-8dot3 file names. The display is the same as the display for /n, but the short name is inserted before the long name.

@Adrian the root cause is your paths containing a space. Since I'm not a windows batch expert nor I have access to windows command prompt I can't really help, sorry. Your goal is to runjavac "C:UsersAdrian $ProjectFile.java"command or similar using escaped path toFile.java.
