I understand how to run my application with command line arguments using the run configuration menu.
The problem I have is that no matter what I update these command line arguments to, eclipse does not reflect these updates when I execute the code.
so far I have set the arguments to:
test1.txt test2.txt dfs
and this will print:
args[0] = test1.txt
args[1] = test2.txt
args[2] = dfs
but if I update the arguments and re-run it, the arguments won't update
How can I "reset" the arguments and re-run the application using the updated arguments.
The above and below both function correctly and it was in fact eclipse that was causing me issues. The problem was resolved with a simple restart of eclipse.
Thanks all.
It is sure to work cause I tried it in mine right before I wrote this answer
There is a situation (bug) where modifying the Run -> Run Configurations arguments does not work, since the actual run configuration being executed is actually hidden from you.
So updating the visible one will not be reflected in your actual run.
Example:
import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class EclipseRunConfigurationTest {
@Test
public void test() {
assertEquals("foo", System.getProperty("runProperty"));
}
}
I shall file a bug report.
The above was run on Eclipse Kepler running on Fedora 20.
For Eclipse Neon Users
Step 1: Click Run -> Run Configurations
Step 2: Click on arguments Tab.
Step 3: insert required arguments in VM Arguments.
Step 4: Click Apply
Step 5: Click Run.
A small update in the solution given by Little Child above, to make it work with arguments having spaces in them. eg first argument - abc def second argument - ghi third argument - jkl mno pqrs
In Program Arguments, give them like this using double quotes
"abc def"
"ghi"
"jkl mno pqrs"
If you don't give spaces it will take abc as first argument and def as second argument and ghi as thrid argument and so on..
